RE: Session Sharing Feasibility
Hi Mitesh, It will depend on several factors - if all you wish is for the cookie to also be sent to struts then this will automatically be done by the browser if the DOMAIN and PATH properties of the cookie are compatible - i.e. will allow the cookie to be passed to the struts application, e.g. if I browse to java.sun.com then I will likely get a cookie with DOMAIN=.sun.com and PATH=/ - so this cookie will be passed to all pages at *.sun.com/. You can possibly get around this (if your struts app is on a different server) by manually generating a new cookie in you CGI/Perl app that has the correct DOMAIN for your struts app - never tried this but it might work and will need to be checked on all browsers that will access the apps! The difficulty may come from the fact that the CGI/Perl cookie may just contain a unique reference to allow the session to be restored in the CGI/Perl application, e.g. like JSESSIONID but almost certainly called something different - and would certainly make no sense to pass this to a struts app. You could clearly get around this by, again manually generating a cookie from the CGI/Perl app that has, say the user id encoded in it. A good source of reference for this may be the Remember Me code at the struts sf site (in the resume project, from memory: http://www.sf.net/projects/struts NB: You will need to be extremely careful as clearly it would be easy to spoof a cookie to the struts app with a user id and if no validation is done on password or anything else then this would be all that would be necessary to bypass the security! My preferred option would be to expose a service from the CGI/Perl app that allowed verification of whether a user has a valid session and has securely logged-on to that app. A simple page that returned a success/fail would be sufficient - this can be queried easily from a struts action and could give you single sign-on type capability. You could possibly extend this to expose some other information from the session but again, this may be a means to leak sensitive information from the application so a lot of care must be taken here! You could go as far as securing the channel between the two servers with SSL and also having a means of the struts server safely identifying itself, passing a client cert from the struts app would clearly be a nice option but may be overly complex for your needs. If both apps are on the same server then only accepting requests from localhost/127.0.0.1 in this verification page may be sufficient for your needs? Alternatively, you may want to investigate other offerings for single sign-on capability but the difficulty may be finding a method that is compatible with both the CGI/Perl app and struts - and does not require extensive modification of the session handling in your existing CGI/Perl app - others here may have some options you may be able to try. Hope that helps, Hue. -Original Message- From: Kapadia Mitesh-C23457 [mailto:[EMAIL PROTECTED] Sent: 11 September 2003 19:57 To: [EMAIL PROTECTED] Subject: Session Sharing Feasibility Hello - I have a question about potential sharing of session information between CGI/Perl and STRUTS applications. We have an application written in CGI/Perl on Netscape Enterprise Server in which we would like to have the capability to spawn the user off to a STRUTS application on a different server running WebLogic. The user would then be able to do the necessary processing in the STRUTS application and return to the CGI/Perl application. At present, the CGI/Perl application utilizes cookies to store session information. Is it possible to share session information (user ids, etc) between the two apps? If so, will the use of cookies on both ends make this feasible? What alternatives are there? Any advice and suggestions on the feasibility or infeasibility of this task would be most appreciated.

Date: Mon, 11 Jun 2001 08:20:16 -0700 -- -- Many times pre-processing and post-processing are related, and it can be convenient to handle both in the same Action class. A good way to implement this is to have a seperate Action Mapping for each task (pre-process and post-process). Both mappings would point to the same Action but use different (virtual) paths. Like say /account/setup/pre and /account/setup/post . These may both use the same Action class, which could be package/account/setup.java . The Struts mappings accept an extra parameter property that you can easily test in the Action to see which mapping has been chosen. Your action can then process each task differently, and even go to separate locations if successfuly. By managing this all in the struts-config.xml, you gain a lot of flexbility.

RE: How to get the url containing anchor from request
Hi Marius, I wondered this too - so I had a look. I think the problem here is more of a HTTP one - if you use netcat - one of my most favouritest tools, available from: http://www.atstake.com/research/tools/network_utilities/ ... and run netcat with the following command: X:\nc -l -p 8000 .. this will then have nc listen on port 8000. Putting the following URL in Mozilla or IE: http://localhost:8000/page.do#booboo ... then this will be the result displayed in nc: GET /page.do HTTP/1.1 Host: localhost:8000 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5a) Gecko/20030718 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q= 0.8,image/png,image/jpeg,image/gif;q=0.2,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive ... and as you can see the anchor part is not actually passed to the server. This makes sense if you consider that the anchor is designed to position the browser at a particular point in a page - then there is no point in passing this to the server. More formally, this is probably documented in the HTTP protocol - but it doesn't harm to check. So, unfortunately - I don't think you can get the anchor from the URL as it's never passed as part of the HTTP request. You will need to use QueryString parameters as part of the URL, e.g. http://www.host.tld/myapp/myaction.do?parm1=booboo instead.

RE: [OT] Scheduling
Well, possibly not an elegant answer but... 1) Under *nix we've done this with cron and a bash script that invokes wget to launch a servlet process. 2) Under Windows we've used a VBS script via at/winat/Scheduled Tasks and Microsoft.XMLHTTPRequest to initiate a HTTP connection to launch a servlet process. Both have been very reliable (in fact both are in very widespread use on several servers) - and this is nice as it does not require any 3rd party components. If this is along the lines of what you're trying to do let me know and I can post some code. As regards Weblogic, there's possibly a more elegant solution, but sorry don't use it - so don't know.

RE: Tiles not generating page properly
Hey Carl-Eric,
If you're still stuck and you've got a zip file with this cut-down code in
it - email it to me at the above email address and I'll try debugging it -
as I'm interested to know what the problem is too. I personally still use
NetBeans and have the struts source setup so this should not take long -
debugging in eclipse is still a mystery to me!
BTW we also use Debian and the tomcat4 .deb and use tiles in production and
have not seen this issue - which makes me even more curious!
Hue.

Subject: Re: Tiles not generating page properly
Can you post some more info on the version of struts and the container.
Sure:
My app is running on a Debian woody system, using Java 1.3.1
(Blackdown-1.3.1-02b-FCS) and the Debian-packaged Tomcat 4.0.4-4.
The Struts and Tiles files are the ones right out of the
jakarta-struts-1.1.zip on the Jakarta site, all just dumped into the
WEB-INF/lib directory.
Whenever I get problems I don't understand my next port-of-call
is to debug
the app with the struts source present to see the flow through
my code and
the logic and flow through the struts code. It will depend on
your IDE how
to configure this but if you can post details of that too - I'm
sure someone
will jump-in to help.
I'd do that too, but I'm not sure how. The app, its database and
everything
else is on the Debian machine, but my desktop is on a different machine,
running under Win2K. Is it possible to step through stuff on the SSH
console?
Alternatively, if you're really stuck and you can produce a small
stripped-down version of the problem with source code - then I'm sure
someone will help. If this is a bug with tiles then it's better
for everyone
that it is fixed.
I *am* really stuck at the moment ;-)
What I included in my original post is all of the relevant code.
None of my
custom Actions or classes are called at the time this happens,
this is the
first entry point to the application. I tried the following, though: I
reduced the layout.jsp to the bare minimum:
---layout.jsp---
%@ taglib uri=/tags/struts-tiles prefix=tiles %
%@ taglib uri=/tags/struts-html-el prefix=html-el %
%@ taglib uri=/tags/struts-bean-el prefix=bean-el %

editArea:br/
!!tiles:insert attribute=editArea/!!br/
help:br/
!!bean-el:message key=${help}/!!br/
/body
/html
---
The first bean-el:message works, it even gives me the correct
message for
the key I inserted in the tiles-defs.xml. The menu, which is not
overridden
by the extending definition and is just empty.jsp in the master
definition
works as well: It just outputs !! !!. The editArea, which *is*
overridden, doesn't work: It outputs the first !! and then
nothing. I had
a look at the code created by Tomcat for the layout.jsp
(layout$jsp.java),
there's nothing really suspicious there:
---snippet of layout$jsp.java---

happens but is silently eaten somewhere. No Exceptions show up in
catalina.out or anywhere else.

RE: PLEASE HELP with Exception in error.jsp with Tiles
Hi Richard,
First things first - ditch 1.4.1 and get 1.4.2 - I've had endless unusual
problems with 1.4.1 - except the very latest release - but 1.4.2 seems
faster to me as well. Hmmm - lots to look through ... msanger - Microsoft
make you that mad, eh?
It looks to me like a further exception is being thrown in the error.jsp
(possibly relating to bean:message key=errorPage.heading - is this line
correct?).
My advice would be to simplify the error.jsp significantly (i.e. start with
static content) and build it back gradually. I remember a post a while ago
about a gotcha in that when using tiles the error page appears after the
already committed content of the tiles - so you may need to consider this
too?
Good luck!
Hue.

Subject: PLEASE HELP with Exception in error.jsp with Tiles
Sorry to plead, but I have been fighting this for the better part of two
days now. I've done a line by line review of just about all of my code.
Cannot find anything that appears out of whack - compared to similar
programs that are working.
Would really appreciate any tips or suggestions on how to track this down.
Let me know if there is additional documentation needed.
First, I am running the regular Struts 1.1 production release on
Windows XP
using Sun Java 1.4.1.
In my main JSP I'm running into some type of exception that is
causing me to
switch to my error.jsp. However it never makes it there and I get
about 2/3
of my original JSP page. This only occurs when I encounter an error in a
multi-line update.
I've turned on logging for the tiles and appropriate struts classes. The
most I can see is that I'm getting an NPE in:
org.apache.struts.taglib.html.MessagesTag.doAfterBody(MessagesTag.
java:312)
Below is my error.jsp file and the exception stack trace (sorry, its long
chain of exceptions). Each exception refers to the same line in my main
JSP - 849 - which is this line, I've just finished the /tiles:put tag
for an inline put, and am encountering the /tiles:insert to
end my tiles
structure (I've included several lines after it):
/*line 849*/ if (_jspx_th_tiles_insert_0.doEndTag() ==

out.write(\r\n);
out.write(!-- html-el:javascript formName=\subjectAspectsForm\
dynamicJavascript=\true\ staticJavascript=\true\ htmlComment=\true\
cdata=\false\/ --\r\n\r\n);
} catch (Throwable t) {
out = _jspx_out;
if (out != null out.getBufferSize() != 0)
out.clearBuffer();
if (pageContext != null) pageContext.handlePageException(t);
} finally {
if (_jspxFactory != null)

RE: HibernatePlugIn for struts (a few questions)
Hi Bill, Not related to your Hibernate queries - but I'd also recommend you evaluate (if you've not already done so, of course!) iBATIS. The homepage is at: http://www.ibatis.com/ ... and Rick has written an excellent worked example on getting iBATIS working with Struts that really takes away any initial pain of integrating it and providing a simple, lightweight but extensible interface into iBATIS. http://www.reumann.net/ The only reason I mention this - is not to try and provoke you into more desk pounding - but after my brief evaluation of the two technologies - I preferred iBATIS (by long shot). I have also been watching various discussions recently and I notice several people moving from Hibernate - iBATIS but I've not seen any discussions on moving the other way. I thought I'd pass this on in case you had not had opportunity or had not considered iBATIS. Hue. -Original Message- From: Bill Chmura [mailto:[EMAIL PROTECTED] Sent: 27 August 2003 07:20 To: 'Struts Users Mailing List' Subject: HibernatePlugIn for struts (a few questions) Okay, I managed after much beating and desk pounding got hibernate to work in struts. It just took some patience. Anyway, I now have two questions: #1 - Regarding the plugin that stuffs a hibernate sessionFactory into the servletContext. In my code I can use hibernate two ways: SessionFactory sessionFactory = (SessionFactory) getServlet().getServletContext().getAttribute(SessionFactory.class.getNa me()); or SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); The first is using the plugIn. Is the difference basically that the plug in will close it when the app closes, and there is no repeated cost if creating the session factory (as I believe it would only be done once)? The second would be created every time the action was invoked thus incuring mucho overhead yes? #2 - Best practices. I want to separate out the business logic into their own objects which I would then create and call different function on which would return data. To do this they need to have access to hibernate. What is the best way to pass down to these objects the connection to hibernate? Should I just pass a servletContext, or actually a SessionFactory reference. I am betting on the later as it would give a greater seperation from the app. For example I may have an object called CorporateInfo. Methods would be stuff like getEvilDepartments(), getUselessDepartments(), getAllDepartments(). They would return lists of beans retrieved from hibernate. My action could then use them. I would probably put any modification code down at that level (like fireAllEmployeesInDepartment(department) ). Feedback? Okay, I am going to stand up now for the first time in like 5 hours - probably followed by passing out...

RE: tiles: condition in tile definition
As you've probably found-out this syntax does not work in tiles-defs.xml(!) ... but a similar result can be achieved in a definition in a JSP page. One option may be to define your loginform attribute as say, mainForm.jsp that could then use el (or logic) tags to determine which jsp to include. A better option may be to use the extends capability of tiles to define 2 layouts that extend layout and define the first, e.g. page.login with the login form and e.g. page.usermenu with the menu form. You can then forward to the desired layout based-on a condition, as you have indicated.

Hello,
I'm trying to convert some pages from Struts tags to JSTL for the next

[Struts 1.1, Tomcat 4.1.24, Java 1.4.2, JSTL 1.0.3]

The Form object (instanceForm) contains a DynaBean (dynamic) as one

The name of the particular field within the DynaBean is stored in a
local variable (fieldName) that is been populated in a loop.
The following Struts tag works fine:
bean:write name=instanceForm property='%= dynamic.+fieldName %'/
I'm new to JSTL, and I've tried various forms similar to those below
without success. Is what I'm trying to do possible?
c:out value='%= ${instanceForm.dynamic.+fieldName %}' /
c:out value=${instanceForm.dynamic.%=fieldName%} /
c:out value=${instanceForm.dynamic.${fieldName}} /
Anyone have any ideas? Or should I stick with the Struts tags for this?

RE: Problem converting from Struts tags to JSTL
Hi Kev,
Sorry - I missed the fieldName being dynamic bit(!). I think you may want to
consider moving to JSTL for the loop bit so it will save having to do
conversions but I think the following will achieve what you're trying to do:
bean:define id=fieldNameBean value=%=fieldName% /
c:out value=${instanceForm.dynamic.map[fieldNameBean]} default=uh? /
BTW you could remove the default=uh? bit - I use this for testing so that
I can at least see the loop working.
I don't tend to mix EL with non-EL so this may not be the optimum solution -
someone else may have a better idea - as I guess the performance will be
slower and heavier due to having to copy a value to a bean in page scope.
Hue.

I think the problem is with the nested evaluation - combining the

RE: Problem converting from Struts tags to JSTL
Ah good - glad it's sorted.
BTW, as a matter of interest - I tend to use DynaActionForm as a nested bean
in a DynaActionForm. This allows the properties of the Dyna to be defined in
struts-config (may not suit you of course, just thought I'd mention it in
case it's of use):
// Get reference to DynaActionForm passed to action

Hi Hue - thanks for your efforts.
I actually just managed to get it working as your mail arrived.
Here is what I had to do:
1) Change the JSP to be
c:out value=${instanceForm.dynamic.map[fieldName]} /
(actually just like you suggested)
2) This is the interesting bit - I had to subclass BasicDynaBean
to expose a getMap() method. This is what DynaActionForm
does, and was discussed on the commons-dev list in Nov2002
by Craig, David, and co.
I then had to pass that new class as the 2nd param of the
constructor of BasicDynaClass that creates the instance for me.
Thanks again,
Kev

Hi Kev,
Sorry - I missed the fieldName being dynamic bit(!). I think
you may want to consider moving to JSTL for the loop bit so
it will save having to do conversions but I think the
following will achieve what you're trying to do:
bean:define id=fieldNameBean value=%=fieldName% /
c:out value=${instanceForm.dynamic.map[fieldNameBean]}
default=uh? /
BTW you could remove the default=uh? bit - I use this for
testing so that I can at least see the loop working.
I don't tend to mix EL with non-EL so this may not be the
optimum solution - someone else may have a better idea - as I
guess the performance will be slower and heavier due to
having to copy a value to a bean in page scope.
Hue.

Thanks for the pointer to the user guide, but unfortunately
it doesn't
help.
I tried:
c:out value=${instanceForm.dynamic.map.%=fieldName%} /
And
c:out value='%=${instanceForm.dynamic.map.+fieldName+}%' /
And
c:out value=${instanceForm.dynamic.map.${fieldName}} /
But those didn't work either.
I think the problem is with the nested evaluation - combining the
scriptlet and the EL.
Any other ideas?

Subject: Problem converting from Struts tags to JSTL
Hello,
I'm trying to convert some pages from Struts tags to JSTL
for the next
iteration of our product and I've hit a problem. [Struts
1.1, Tomcat
4.1.24, Java 1.4.2, JSTL 1.0.3]
I need to be able to dynamically access nested fields
of my form
object.
The Form object (instanceForm) contains a DynaBean
(dynamic) as one of
its fields. The fields of the DynaBean are what I'm trying
to access.
The name of the particular field within the DynaBean is
stored in
a local variable (fieldName) that is been populated in a loop.
The following Struts tag works fine:
bean:write name=instanceForm property='%=
dynamic.+fieldName
%'/
I'm new to JSTL, and I've tried various forms similar to
those below
without success. Is what I'm trying to do possible?
c:out value='%= ${instanceForm.dynamic.+fieldName %}'
/ c:out
value=${instanceForm.dynamic

Subject: How to get a String object from request scope.
Hi gurus.
I got one Action servlet class and one jsp.
If the action servlet is successfully processed, it's forwarded to the
jsp.
In the Action servlet, there's a following statement.
String my_name = JACK;
request.setAttributte(MY_NAME,my_name);
return (mapping.findForward(success));
Now I wanna get the MY_NAME property with a struts tag in the jsp
which is redirected from the Action servlet.
I don't know how to make it since the instance(my_name) in the action
servlet is a just String Object...not a javabean.
Thanks in advance.

RE: [OT] A date utility? anyone, pls help
I read a lot about BigDate - but it's shareware @ $10, I think. Never had
to use it myself but here's the link:
http://mindprod.com/jgloss/bigdate.html#BIGDATE
There is also a very good tutorial on dates (see Computer Dating link),
here:
http://java.sun.com/people/linden/intro.html
Specifically for what you're asking ... the number of years between 2
dates? (are you sure you mean years?) try this:
java.lang.Math.abs(
myDate1.getTime()-myDate2.getTime() )/1000/3600/24/365.25
i.e. get abs difference in millisecs and convert to years - but your version
of a year may vary (i.e. you may consider 365 to be a year)!
BTW to setup date values for testing try the following code:
java.text.DateFormat df = new java.text.SimpleDateFormat( .MMM.dd );
try {
java.util.Date myDate1 = df.parse(1971.OCT.02);
java.util.Date myDate2 = df.parse(1987.JAN.09);
System.out.println( java.lang.Math.abs(
myDate1.getTime()-myDate2.getTime() )/1000/3600/24/365.25 );
} catch (Exception ex) {
System.out.println( ex.toString() );
}

RE: Horizon: a view management plugin
I must confess to being a bit confused! What is the difference between your approach and getting an instance of a Dyna, viz: DynaActionFormClass dafc = DynaActionFormClass.getDynaActionFormClass(Dyna-Definition-Name-In-Struts-C onfig); DynaActionForm myBean = (DynaActionForm) dafc.newInstance(); At least with the above approach the beans are stored in struts-config in the usual struts syntax - it's just they're not used in the action name parameter - but are created on-the-fly in an action (or wherever) with the above code. I'm concerned I may be missing some obvious advantage to your approach - hence the reason for the question!

When I see dynabean are you saying BeanUtils.DynaBean and what is a 'view bean', do you mean a Action Form ? yes If so what is the difference between your plugin and a DynaActionForm ? i think, actually, there is none... the difference is for what i use the view beans for: transfering data from actions to build combobox on form and present data that isn't on a form. i know i can use the form itself to put a collection to build a combobox and use another form bean property to store the user input but it is less confusing if i define forms with only the properties the user can enter data and another bean for transmitting data (dto... in my case i call it view bean). before the plugin i had to define a new java class (attributes + getters/setters) for each new dto i wanted, now, i only need to add some lines to a xml file... Given that your plugin is generally useful then there are several options : 1) Since web space can gotten for free now days you could always post it on a site with some documentation on how to use it. i will see what i can do... 2) We are using the http://www.sf.net/projects/struts site as an incubator for projects you can post there to see if there is interest. thank you for the tip... 3) Find someone else with a struts web site, that would host it.

RE: alternative to hidden?
A sort-of server-side control state ... hmmm - scarey. A better option might be to incoporate all the state in a hidden field in the form that can be added by a tag lib - a la .NET _VIEWSTATE and then re-created when the form is submitted. I can think of lots of concerns with what you describe - for instance, a user with 2 instances of the browser open could easily cause carnage with this facility. An alternative is to identify the exact server state by a response token that would be unique per browser instance - but then this would need to be in a hidden field, anyway - catch 22. I like the idea in concept - I think, though there may be fundamental limitations to HTTP that would unfortunately scupper any neat solutions for this - but others may have some clever ideas.

RE: where is JSESSIONID?
If you wish to see struts' cookies in the browser - then the easiest way is to use Mozilla (http://www.mozilla.org/). After browsing your struts app then use the following mechanism to find the cookie that is being used: Moz: Edit... Preferences... Privacy Security / Cookies Select Manage Stored Cookies Look for the site, e.g. localhost, www.domain.tld There should be a cookie named JSESSIONID - click on it to see the session id More info on per session cookies -- IE does not seem to save the cookie to disk as the cookie is a per session cookie. A per session cookie is a cookie that is only valid for the current session - distinguished from a non-per session cookie by the fact a per session cookie does not have an EXPIRES attribute. See the following output from nc (http://www.atstake.com/research/tools/network_utilities/) that makes this clearer: 1) Output from a site with a per session cookie: -- X:\nc 127.0.0.1 8081 GET /index.jsp HTTP/1.0 HTTP/1.1 200 OK Content-Type: text/html;ISO-8859-1 Connection: close Date: Wed, 06 Aug 2003 12:04:34 GMT Server: Apache Tomcat/4.0.6 (HTTP/1.1 Connector) Set-Cookie: JSESSIONID=5BF64BD681D362A1962D81AF7A3B4362;Path=/ 2) Output from a site with a NON-per session cookie: -- X:\nc java.sun.com 8081 GET / HTTP/1.0 HTTP/1.1 200 OK Server: Netscape-Enterprise/6.0 Date: Sat, 16 Aug 2003 15:09:16 GMT Content-type: text/html Cache-control: no-cache=set-cookie Set-Cookie: SUN_ID=12.34.56.78:1615:1061046556:19410; EXPIRES=Wednesday, 31-Dec-2025 23:59:59 GMT; DOMAIN=.sun.com; PATH=/ Note the addition of the EXPIRES information in the second example that will indicate to the browser that this is _not_ a per session cookie.

RE: persisting session id
Well, one option I can think of would be to send a non-per session cookie (with an EXPIRES attribute) - you probably will need to disable tomcat from sending cookies as sending 2 JSESSIONID cookies will probably confuse the browser! (this is configured in Tomcat with cookies=false attribute in the Context for your webapp). The following code should go at the very top of page(s) that are accessed frequently by users - this will generate a persistent cookie. The example uses a cookie that will expire after 24 hours - the time will be updated each time they hit the page - so should expire 24 hours after their last access of your app. Presumably you'll also need to set the expiration time for the session to at least 24 hours, too - so when the cookie is sent back to the server the session still exists! (Hopefully you don't have too many users so session state will not use too much memory!). % // Setup a calendar to calculate the expires date and time (in GMT) java.util.Calendar expires = java.util.Calendar.getInstance(); expires.setTimeZone( java.util.TimeZone.getTimeZone(GMT) ); // Add-on number of hours, e.g. 24 hours expires.add( java.util.Calendar.HOUR, 24 ); // Create a format object to output the date and time in the desired format (and in GMT) java.text.SimpleDateFormat format = new java.text.SimpleDateFormat(EEE, dd MMM HH:mm:ss zzz,java.util.Locale.US); format.setTimeZone( java.util.TimeZone.getTimeZone(GMT) ); // Send a cookie with the required information response.setHeader(Set-Cookie,JSESSIONID=+ session.getId() +; EXPIRES=+ format.format(expires.getTime()) +; PATH=/); % NB: Code has been written with fully-qualified classes so it will run as is - alternatively shorten the classes and us page imports. I've quickly checked code - it does compile and does send a cookie but you may need to check syntax of the cookie sent. Let me know if it works!

RE: Global Forwards and Tiles
Hi David,
I think the fundamental problem here is that global-forwards are not
available to be called from outside the server. If one considers the URL one
might use to call global-forwards, e.g.:
http://myHost/myApp/myForward
... then this will not be passed-to struts - and will instead look for a
servlet mapping matching the myForward pattern - and probably won't find
one.
If you look at the result of a global-forwards/forward generated by say:
html:link forward=myForwardForward Me!/html:link
... e.g. where the following configures the forward in struts-config to
forward to the myAction action:
...
global-forwards
...
forward name=myForward path=/do/myAction /
...
/global-forwards
...
... then it will likely be of the form when rendered to HTML:
a href=/do/myActionForward Me!/a
... then this _will_ go through the struts servlet and be correctly mapped
to an action.
If you wanted a way of configuring a method of calling any tiles def from a
jsp then one option would be to have a generic action than can fwd to the
tiles def, e.g. define a bean and action in struts-config:
...
form-beans
...
form-bean name=tilesDef
type=org.apache.struts.action.DynaActionForm
form-property name=tilesDef type=java.lang.String /
/form-bean
...
/form-beans
...
...
action-mappings
...
action path=/tilesDefFwd
type=tld.domain.actions.TilesDefFwdAction
name=tilesDef
scope=request
forward
name=tiles-def-not-passed
path=/error-tiles-def-not-passed.jsp /
/action
...
/action-mappings
...
The action code would look like this (ok, error handling could be a bit
tighter(!)) but this gives the idea:
package tld.domain.actions;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletContext;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.DynaActionForm;
public final class TilesDefFwdAction extends Action {
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
String tilesDef = ;
// Get our parameter(s) from the form
DynaActionForm dynaForm = (DynaActionForm) form;
try {
tilesDef = dynaForm.get(tilesDef).toString();
} catch (Exception ex) {
// Something went wrong - send to error page
return ( mapping.findForward(tiles-def-not-passed) );
}
// Forward to tiles def
return ( new ActionForward(tilesDef,false) );
}
}
This would then allow a URL of the following format, e.g:
http://www.domain.tld/myApp/do/tilesDefFwd?tilesDef=myDef
... that would then forward to the tiles def myDef, e.g.
html:link page=/do/tilesDefFwd?tilesDef=myDefForward Me To Tiles
Def!/html:link
Alternatively, there may already be a mechanism to do this natively in
struts - but have attached the above code as this is what I wrote when I was
getting to grips with forwards/actions/tiles-defs etc - and hopefully it
will be of some help!
Hue.

Subject: Global Forwards and Tiles
I've attached a discussion with a fellow developer
regarding Global Forwards and Tiles. The tiles-defs
are in xml if that makes any difference.
*
Here's the delima. I can configure a Global Forward
that maps to my tiles definition. If I refer to this
global forward from an Action then it finds my tile
def. But, If I call this global forward from a jsp,
then it craps out. But normally you can call a global
forward from a JSP and it will work fine, as long as
you are not using tiles defs. So, it seems like if I
want to get from one JSP to another tiles def, then I
have to go through a Action, which could be a
ForwardAction. My Actions can use my global forwards,
but my pages cannot. It's kind of weird, but I at
least I understand what I can and can't do now.

So are thought is that Global ActionForwards defined
in the global-forwards section of the
struts-config.xml really don't go through the
RE: [OT] Interesting JSF info
Sorry, long reply. My first thoughts on JSF were that it looked really powerful and was a blast of fresh air. I think it's an excellent idea to have the ability to define controls and then have them rendered in a manner suitable for the target device with pluggable renderers. My only concern was that this was being done using XSLT (I think it is) - and from a personal experience viewpoint I've always found XSLT a resource hog on the server and slow when used by lots of users - but I am happy to be persuaded once I get to actually trying JSF. I'm grateful to whoever it was who provided the struts-JSF integration work as this allows me to see JSF working with my favourite web development framework! It's on my list to check-out and will happen in the next couple of weeks - so I'll be happy to report some more informed comments at that point! I'm very enthusiastic about Java Everywhere. Sun was really strong when all it did was talk java - java was _and_ _still_ _is_ a fantastic vision - you've just got to look at the number of mobile phone companies who've licenced java for mobile phones just recently. Java has experienced slower take-up than initially expected - but one can't help feeling that the view that was touted frequently a couple of years ago that java would die-out because it didn't explode overnight and wasn't immediately used for everything - has been proven completely false. Java is growing - and as netcraft reported - it is growing very rapidly: http://news.netcraft.com/archives/2003/07/23/jsp_continues_fast_growth_on_a_ surprisingly_diverse_set_of_operating_systems.html With the use of java on mobile phones - that will almost certainly grow-up to become devices to rival our current set of PDA-type devices - bringing java with them as the central VM on these devices. Sun obviously needs to offer something to counter Microsoft's .NET initiative. I know what I'm talking about here - I've run a few .NET courses and developed a few .NET apps. My problem with .NET and with many other people I speak to - is that it's tied totally to the Windows Operating System and involves a massive learning curve for traditional VB and ASP developers. That said, show a developer ASP.NET's ability to do GUI development of web applications with viewstate and transparent execution of server-side button code - just like VB does - and they can finally envisage writing web applications rather than GUI-based ones. Then show them a demo of a cut-down version of the same page working seamlessly with a downlevel (Microsoft-speak for non-Microsoft!) browser or handheld device or WAP phone and they can envisage writing apps for mobile devices as well - in exactly the same GUI way they've been used to writing VB apps. How can this equivalent functionality be catered for in struts? Well, for a start you need to code for the specific device - struts cannot magically produce WML instead of HTML for a WAP device. Sure, you can do it - but only by writing the JSP page in a way that it will output WML, changing the ContentType header appropriately as well. Ok, my personal view, at the moment is that a well-designed struts app will allow proper separation of view, anyway so it just needs for a template in WML to be created - chances are this will give a better end result. My understanding is that JSF will bring this functionality to web-based java applications - hopefully with a nice GUI development environment - so this will offer the same kind of oh, wow reaction that showing this kind of demo to the uninitiated always does! But, maybe - just maybe, JSF will deliver on the early promises and will become a truly indispensible view technology (and maybe a lot more) - time, as always will tell. Again, the licensing model for JSF will be another thing that one needs to be comfortable with - I understand it will not be Open Source ... but then neither is java. If Sun start asking for silly royalties: per server; per CPU; per Company; then, sorry I'm not sure it's a goer - as .NET is free for unlimited deployment: public-facing or whatever - it's only the Visual Studio.NET development IDE that is charged-for. Ok, admittedly only on a Microsoft OS so they've had money anyway. The only way I can see that Sun can get close to the java everywhere-type vision is that the use of JSF will be as unencumbered as java currently is and will realise widescale use - Ok, where's the revenue stream in that you might ask - well don't ask me because I don't immediately know ... but I can see how it is great for java (and for Sun) and for the rest of us if it turns-out half as good as it promises to be.

The rationale for this approach is to make it easy to replicate a site using the same, or mostly the same, pages. But an interesting snafu employing Netscape (as opposed to IE) has arisen with this schema: you can evoke the appropriate forward from both browsers when submitting a form, yet if you attempt to link to the same page via an href, IE finds its way to the correct page but Netscape apparently searches for the forward in the same directory as the calling page (paying no attention to the action-mapping). I was wondering if anyone had encountered this problem and knew of a work-around.

RE: Deployment of Struts App in Linux/Tomcat
André, It does depend on quite a few factors, if you're able to provide some info on the following someone here may be able to help: 1) What version of tomcat? i.e. 4.0.x, 3.x, 4.1.x? 2) Does tomcat serve pages correctly now, i.e. what does browsing to the following URL give (replace 127.0.0.1 with server ip address if not on server): http://127.0.0.1:8081/ Does it give an error or does tomcat holding page come-up, i.e. is tomcat running OK? You might also want to try replacing 8081 with 8180 which some distros use for TC (Debian, for example). 3) It should only be necessary to deploy the .war to the expected directory and restart TC. Although it could also be necessary to manually unpack the war depending on how TC is configured. What directory are you attempting to deploy to? 4) A summary of what your friend has already tried and why you think paths might be the problem. BTW deploying a struts app on TC can require some minor changes if TC is running under a Java Security Manager, JSM, as documented here: http://jakarta.apache.org/struts/userGuide/installation.html (sub-section Running Struts Applications Under A Security Manager) Hue. -Original Message- From: Andre Michel [mailto:[EMAIL PROTECTED] Sent: 11 August 2003 18:43 To: [EMAIL PROTECTED] Subject: Deployment of Struts App in Linux/Tomcat Hello, a friend of mine is trying to deploy a Struts application on a linux server and is encountering severe problems (with pathes in particular).

RE: another question to tiles
Reinhard, What you are asking - I do not believe to be straightforward and I have not seen any sample code showing how to do this. I have often considered doing this and remember a few posts from Cedric on this topic, the following one in particular: http://marc.theaimsgroup.com/?l=struts-userm=104630401320509w=2 ... in which Cedric gives the link to: http://www.lifl.fr/~dumoulin/howto/writeAFactory.doc Here are some other links I found which I've kept to one side when I get around to looking at this (sorry - all may not be relevant): http://marc.theaimsgroup.com/?l=struts-userm=105654460717516w=2 http://marc.theaimsgroup.com/?l=struts-userm=105366427120584w=2 http://marc.theaimsgroup.com/?l=struts-userm=105089975605717w=2 http://marc.theaimsgroup.com/?l=struts-userm=104914441232186w=2 http://marc.theaimsgroup.com/?l=struts-userm=104748278524593w=2 http://marc.theaimsgroup.com/?l=struts-userm=104670782103419w=2 Hue. -Original Message- From: Reinhard [mailto:[EMAIL PROTECTED] Sent: 11 August 2003 14:09 To: Struts Users Mailing List Subject: Re: another question to tiles Hi Cal, many thanks for your answer! If you check out the Advanced Manual on the Tiles site there is a section on dynamic definitions. http://www.lifl.fr/~dumoulin/tiles/ I was surprised about this hint, cause I startet with this documents. So I rechecked to document and - IMHO - it's not talking about dynamic handling, like I asked for. The dynamic stuff is, having various alternatives configured, switch between them. I already reached that step. With the ActionForward I create Forwards, which are NOT in the struts-config. Now I would like to do something similar with the tiles, to cleanup the tiles-config. Nothing, I couldn't live without, but I think, the less you have to configure, the more stable is the application. Just an idea. I came to 8.4 writing your own definition factory. There's a (big) warning, that it's outdated. The document is from last year, so I have no idea about the changes from then on. The homepage of the creator is although frozen. Is the tiles-definition-factory similar to the definition-factory of struts? The later was easy to implement. But what is the counterpart to the ActionForward in tiles? The technique I use is the same as Cedric's example - but I simplified a bit. The downside is a trip to an action for each page to determine the layout. I thought, that I simplified it too - and yes, I also have to trip to an action. - Do you have any experiences about the cost of the additional trip to an action? - Why do you write an extra cookie. Is it not ok, to store the user-settings in the session-context? - Do you know, where the default locale comes from? Does it come from the user-agent (browser) or from the server-environment? kind regards Reinhard - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --- Incoming mail is certified Virus Free.

If I remove the datasource from the struts-config the error goes away (of course cannot connect to a datasource but the jsp comes up). In versions RC1 or earlier the problem does not exist. The main difference from RC2,1.1 Final and earlier versions starting from RC1 is (from release notes): In RC2, the Commons-DBCP and Commons-Pool dependencies have been removed. These are replaced with a dependency on the Struts-Legacy package, containing the GenericDataSource and GenericConnection classes from Struts 1.0.2. These are distributed for J2SE 1.3 but may be recompiled for J2SE 1.4. Other DataSource implementations may be plugged in (recommended). RC2 is dependent upon Commons FileUpload RC1. The final release of Struts 1.1 cannot happen until this dependency is updated to a final release of FileUpload. All other dependencies are in their final release. Other changes since RC1 have been routine fixes and refactorings. I have tried using DBCP and General methods of connecting using the mysql driver and both will not work. The RC2 and Struts Final 1.1 work fine in Tomcat 4.1 but do not work in Resin. I am using J2SE 1.4 on Tomcat and Resin Any suggestions? Thanks, Barry --- Incoming mail is certified Virus Free.

RE: Apache Tomcat web servers
Hi yan, Memset support only the virtual server. They are well versed in Linux - RH and Debian certainly and they're bright guys from what I've seen. They provide unmetered bandwidth on a shared connection and you can install whatever you want to install. I'm sure they'll help you with Apache - but not sure what their abilities are on TC - my guess is you'll get minimal help with TC setup or configuration - but hey use the TC list - it's great! After having grief with TC hosting (not tried kgbinternet, though!) - it seemed much easier to roll our own. We tested a Debian production server in-house with Apache, Tomcat and mod_ssl (for Apache) - with multiple domains for apache (and obviously TC). With full root access it has proved _much_ less grief than trying to get equivalent functionality from a dedicated TC hosting company - but maybe we are just awkward! Hope that helps, Hue. -Original Message- From: yan [mailto:[EMAIL PROTECTED] Sent: 10 August 2003 13:49 To: Struts Users Mailing List Subject: Apache Tomcat web servers Thanks for the advice Hue, you have given me a lot to go on there - much appreciated.

RE: Welcome.do;jsessionid=C36048429636E35FB1ECAA5978E23132 [Solved for me]
I had the same problem and sorted it thus:
1) Create a new page, say index_entry.jsp with the following content (it
is assumed your previous entry point was index.jsp):
HTML
HEADMETA HTTP-EQUIV=Refresh CONTENT=0;URL=index.jsp/HEAD
BODY/BODY
/HTML
(Ok, if you have a particularly complex app structure, with modules etc -
then you may need to change above path to index.jsp programmatically).
2) Change your welcome file in the app's web.xml to index_entry.jsp
...
welcome-file-list
welcome-fileindex_entry.jsp/welcome-file
/welcome-file-list
...
3) Explanation (long):
This technique only works for me on tomcat as, tomcat does not seem to send
a session cookie (nor indeed start a session) for the initial request to the
root of the webapp, e.g. http://host.domain.tld/ - it only starts a session
on request to a resource in the webapp, e.g. page/action. This is probably
part of the spec - don't know because I haven't checked yet. NB: This was
using TC 4.0.6 (bundled with netbeans on Windows 2000 with Sun's JDK 1.4.2).
a) NO COOKIE FROM WEBAPP ROOT WITH RETURNED 302
When browsing to http://host.domain.tld/ - a cookie is not sent with the 302
(Moved Temporarily) response that re-directs to the welcome file, e.g.
index_entry.jsp. See the following output from nc
(http://www.atstake.com/research/tools/network_utilities/):

b) BROWSER REQUESTS WELCOME FILE, e.g. index_entry.jsp
This time a cookie is sent server-browser with JSESSIONID in it. The server
is not aware yet that the browser can send cookies (as one has not been sent
from browser-server yet) - so if any links in this page use URL Rewriting
then they will have the JSESSIONID appended to ensure session state is
maintained.
X:\nc 127.0.0.1 8081

Content-Type: text/html;ISO-8859-1

HTML
HEADMETA HTTP-EQUIV=Refresh CONTENT=0;URL=index.jsp/HEAD
BODY/BODY
/HTML
c) BROWSER REQUESTS REAL WELCOME FILE, e.g. index.jsp
This time the cookie is sent browser-server so the server is now aware that
the browser can send cookies. Any links in this page will not now use URL
Rewriting (unless of course browser has cookies disabled).
Well that works for me - hopefully it will help someone else.
Hue.

RE: Apache Tomcat web servers
Hi yan, I would be inclined to keep-away from ISPs who do not have good and *extensively* proven experience with JSP and only go with those who are specifically recommended to you for JSP. I fell-out with a UK-based ISP (servers hosted in the US/Canada) in the last 6 months after failure-after-failure with Tomcat - although they apparently supported tomcat. They felt I was being unreasonable if I complained that TC was down frequently as they claimed their servers were still up and serving static content - so this was fine in their mind - the simple website in question was finally offline for at least 2 weeks. We were being blamed for apparent errors in the pages although the website had not been changed and had worked flawlessly for 3 months prior to this outtage ... and also worked without changes on a fresh download of Tomcat and on every configuration of ours: Windows and Debian Linux with IBM, BEA and Sun's JDKs 1.3-1.4 and under a JSM and without a JSM! We did attempt to get a refund as we'd paid for 12 months hosting in advance - but they refused and unless we wanted to get legal they would not pay up - in the end we transferred to another ISP (easy to do as our DNS is located elsewhere and enabled us to do this). A *costly* lesson. The lessons we learned are: 1) Always keep control of DNS records - and allows easily and quickly moving from a poorly-performing ISP. Ours are with register.com - not cheap but their DNS appears to be very solid and all DNS can be configured online and DNS costs are included in the domain registration costs. There are plenty of other options for other DNS providers, though. 2) Never go with an ISP for technologies they seem to support - only ever go with a technology from an ISP if they specialise in this and really know what they're doing. Recommendations seem to be the key, here - recommendations for kgbinternet seem to crop-up a lot - I haven't personally read a bad word about them yet. 3) For JSP specifically - always consider what _could_ go wrong with hosting and what implications sharing with other sites could have. For instance a private JVM is a really good idea - from a security, performance and reliability viewpoint. Also, consider what effect other services running on the same server could have - for instance we lost tomcat once as, unknown to us - the server was also being used for users just playing about with tomcat - another user had deleted their jserv directory and this caused tomcat to fail to start - taking our site with it. We also had problems wanting to change some settings for the JSM - in order to run Struts/Tiles - this was finally done - but grudgingly only by the above ISP. 4) Consider what version of Tomcat (or other container) you'd like to be running and ask whether this is the version they run and how proactive are they at installing security updates and fixes. When we first investigated the version running with our ISP it was Tomcat 3.2 beta 4(!) - even though 3.3a Final and 4.1.x was also suitable for production. From the Tomcat bug database there appeared to be some very serious security problems with the version they were running: source disclosure, web.xml disclosure etc.! Our Choice ** After trying 4 different shared hosting providers we now use http://www.memset.com/ - who supply a very competitively-priced complete virtual Linux server - with unlimited bandwidth and full root access and control panel to remotely reboot the server, if necessary. There are more options here: http://user-mode-linux.sourceforge.net/uses.html and http://usermodelinux.org/modules.php?name=Newsfile=categoriesop=newindexc atid=12 The option we have provides Debian (they also do RH) Linux, 2 IP Addresses, shared but unlimited 1.5Mbps connection. Ok, admittedly the downside is that if you're not familiar with Linux then you may have a stiff learning curve - but they have excellent and very helpful tech support staff and if you're running Debian apt-get install tomcat gets you a fully-running Tomcat 3.x installation - JVM, JSM (Java Security Manager enabled) all correctly setup! The real advantage is that this allows hosting of multiple domains; full root access; ability to host email if you need it; ability to choose JVM; ability to run apache to front tomcat if you want; ability to run own SSL-enabled service if needed; basically pretty much anything that you can figure-out how to do it! The obvious real downside is that with power comes responsibility and the responsibility is with you to ensure you don't leave the server wide-open to attack; leave an open mail relay; leave a host that can be commandeered in an attack etc. etc. But starting with modest objectives and building from there can get you the service you need without great cost and with full control - and if you're unsure there are plenty of resources from where help can be sought. Hope the above helps, Hue. -Original Message- From: yan [mailto:[EMAIL

RE: Avoiding jsessionid appending in a redirect
Hi Chris, I posted a response to this recently: http://marc.theaimsgroup.com/?l=struts-userm=106018678002719w=2 -Original Message- From: Chris Boulter [mailto:[EMAIL PROTECTED] Sent: 06 August 2003 19:27 To: [EMAIL PROTECTED] Subject: Avoiding jsessionid appending in a redirect Hi, Is there a way to insist that a jsessionid _doesn't_ get appended when returning a redirect from an Action? In my case, I'm redirecting to an external (non-Java) system and the jsessionid is causing the external system problems. I have return new ActionForward(http://some.external.url/options;, true) at the end of my execute() method in the Action. This is exactly the URL to which I want to redirect, but by the time the HTTP response is seen by the browser, it has a jsessionid on the end: HTTP/1.1 302 Moved Temporarily Set-Cookie: . Location: http://some.external.url/options;jsessionid=foo.bar.com-24%3A3f4 I'm using SunONE v6 web server. I've tried adding this to web-apps.xml: session-tracking use-cookies=true use-url-rewriting=false / but it makes no difference. Interestingly, I can't reproduce the problem with TomCat (3.3.1a), although I'm not able to engineer exactly the same environment using TomCat. One theory I have is that Struts (or SunONE?) is interpreting my redirect as the first request to a webapp and, since it doesn't know whether cookies will be accepted, it is using URL rewriting 'just in case'.

RE: Tiles status and feature suggestion WAS accessing Attribute of a parent-tile-definition
Hi Richard, Please see below... -Original Message- From: Richard Tomlinson [mailto:[EMAIL PROTECTED] Sent: 06 August 2003 10:58 To: [EMAIL PROTECTED] Subject: Tiles status and feature suggestion WAS accessing Attribute of a parent-tile-definition 2. Is tiles considered a deprecated technique? I don't think so - and I hope not! I too would like to know the status of Tiles and whether there's any ongoing development with it. I'm looking at redesigning a proprietary composite page handler to use Tiles but see a number of areas where tiles could be improved and where it is not suitable at present to meet all of my requirements: o Firstly, Tiles assumes that a page is composed of multiple content areas where you have one piece of content to an area. This is true for a simplistic site but, as in the case we have, the area on a page can be determined by a condition so that a single area could contain say one of many possible files. An example would be a page where the display differs slightly per category of user and some areas within the template are populated by different content. The ability to conditionally choose a template would also be beneficial. It is possible to create a custom tag to wrap the tiles:put ... in each page but this results in the page being uneditable by the growing number of tiles compliant editors and therefore they would be unable to give any improvement in productivity when creating pages. Has anyone else created pages this way using another composite page handler or product? Tiles works very effectively for us with the logic:equal ... and such tags to conditionally include a tiles:insert ... - we use it extensively and it is very effective. As another poster mentioned - if you need additional capabilities then consider utilising a specific controller. We have been able to achieve what we need just using the aforementioned technique. Alternatively when the page gets too large - we tend to split to include only one portion that then has additional logic as to whether to include additional portions by selectively including other tiles. Performance does seem to suffer a little (or it may just be it's a complex page) - hence our intention to utilise OSCache at various points to avoid re-rendering essentially static data. It may also be that we are not using any tiles-aware IDE - but hopefully any IDE should be aware of logic:... and JSTL so why is this a problem? o Secondly, would it make sense to have a 'static' identifier that could be used to perform the equivalent of a %@ include ... directive to embed content and thereby result in more optimised code? The static attribute would be environment switchable to allow the static functionality to be disabled during development but enabled when deployed in a production environment. I'm not sure I fully understand the question but I presume you're talking about caching static or semi-static portions. We are just starting to use OSCache cache for this - there was a post to the list recently that may discuss this in more detail. Sorry if I haven't understood correctly what you mean. Here's the thread: http://marc.theaimsgroup.com/?l=struts-userm=106002680511323w=2 Here's the link to OSCache: http://www.opensymphony.com/oscache Comments and suggestions, please.

Well, I managed to get it running but I'm definitely not a convert to Netbeans :-( - In Netbeans, go to the Runtime tab and expand the Explorer view until you see the 'Internal Tomcat' server. - Right click on it and change the IDE Integration Mode from Full to Minimum. That seems to get it working. You could also look at the External Tomcat Server feature as an alternative. There's information in the application Help. I think this http://www.netbeans.org/issues/show_bug.cgi?id=32425 is the cause of the problem. In any case, this issue is with Netbeans integration of Tomcat and not with Struts. Related information: James Mitchell has written a guide to setting up a Struts project in Netbeans (version 3.4) http://jakarta.apache.org/struts/faqs/netbeans.html. He's using Ant to build and deploy the web application so that probably gets round the problems by avoiding the IDE's build/deploy features. If you have access to WebSphere Studio it is IMHO a *much* more pleasant experience than Netbeans and importing a WAR is straightforward. I haven't tried Eclipse (on which Websphere Studio is based) with the Sysdeo plugin for Tomcat, but that would be a cheaper (free!) option than WS Studio.

Subject: Design Question - same action, many jsps/views
Hi all,
I've come across a situation which I'm not sure how to handle with
struts.
I have an action which, depending on from which page it's called,
should forward to different jsps pages.
Currently, for each resultant jsp, I create a new action with the exact
same
logic code inside which forwards to the right jsp.
I'm just not sure if this is the right way to do it, because it's
replication of code.
An alternative might be to switch on the input path of the request and
forward to
The right jsp, but I'm not sure if this is right either. This has to
have come up
before, so I'm looking for a best practice solution.
What do you guys reckon?
Thanks,
Brian

RE: Design Question - same action, many jsps/views
Hi Brian,
Yes - I can see your point. Whenever I need to do this (with multi-page
forms, for instance - where the Next button should forward to the next
page) - I use a property on the form, from memory it might be currentPage
(which is numeric for me) that is held as a hidden form property that is
used to do the from logic you are describing. Ok, this was done
specifically as we are using tiles, as I believe this may confuse the
getRequestURI() return value(?).
The alternative may be to use the dispatcher to define a specific entry
point in your action that can call some generic code (i.e. that presumably
you're now concerned about duplicating - and I agree with your concerns) -
and then forward to the correct forward?
Alternatively the struts-workflow extensions may provide additional clues
for you on how this may be done. From memory, we were discouraged from using
this as it had several pre-requisites, like appending something to every
action and actions needing to work in a particular way that was too much
work for us (and I think there some issues using it with tiles?). I think
the new version integrates much better with 1.1 so this may be worth a look,
too?

Subject: RE: Design Question - same action, many jsps/views
Hi Hue,
That's definitely one way to go, but the disadvantage that
I see of using this way is that you presumably have to hard code into
the action, some way of identifying where the request came from. Perhaps
something like:
String input = request.getRequestURI();
if(input.equalsIgnorCase(inputpath1)
return (mapping.findForward(page1));
else if(input.equalsIgnorCase(inputpath2);
return (mapping.findForward(page2));
else if(input.equalsIgnorCase(inputpath3);
return (mapping.findForward(page3));
The previous new action mapping idea means you don't have to do
this I think, which might make it a better solution. What do you
think?
I'm not sure though, and thanks very much for the help.

RE: Simple Tiles question
Erez, Tiles are included in the HTML page like any other 'fragment' - the resultant HTML needs to be properly formed. If the outermost tile or page already has html etc. then the included tiles should not have this - so yes - you need to remove this. For simplicity my tiles are normally self-contained tables, i.e. tabletrtd.../td/tr/table but sometimes are just self-contained rows but can be anything - providing the HTML page that is finally generated from all the tiles is valid.

RE: [OT] Meeting in Paris this Saturday
Who gives a (word removed) if Cedric is going to be in a bookstore this Saturday? I was being sarcastic, not inflammatory, in the traditional hacker sense. I do - and probably some others who subscribe to this list - who will be in Paris and who may be interested in having a face-to-face discussion with the author of tiles - arguably a very important component of struts. Perhaps he will be dipping his freedom fries in freedom dressing sitting by the freedom doors before ordering freedom toast? I presume this is a reference to French President Chirac's stance on the imminent war to disarm Iraq - and the American 'humour' cited at the French people as a whole. In my view - this comment is very inflamatory and I think it has previously been agreed that prejudiced (and potentially racist) comments such as this have no place on this list - in my view whether they are marked as '[OT]' or not. Personally, I have a view on Chirac's stance also - but do not feel this list is the appropriate medium on which to voice it. Neither would I, as you seemed to have - presumed to know Cedric's personal stance on this. Alternatively, you may view that - Cedric is French and all French people will share the same view and traits - and can be insulted and mocked - this then would definitely be racist, in my personal view, of course. And I've been helping people on this list since 1.0 beta, though got preoccupied for a couple of months on my last project. Great - technologies like struts can only survive with list such as these and useful input from individuals such as yourself. I hope your project was completed successfully. Don't like my posts?

I think everyone is entitled to their own views and some of the [OT] posts *are* amusing - but when they may cause personal offence or voice prejudiced views then I think we all have a personal duty to voice our dissatisfaction with the sender. Whether in the sender's view they were meant to be 'humourous' or not or were posted merely to provoke a reaction - I still think they are inappropriate. Dissatisfaction voiced. Yes, I appreciate that Mark's comments should be taken with a 'ladleful of salt' but I do *not* think Mark has '... earned the privilege to flame who he wishes ...' - so, pretty please, Mark - apologise - I believe you have overstepped the mark on this occasion.

RE: [Q] Accessing struts-tiles attribute in a bean?
Great links, Thanks Ted. I suppose the ultimate objective (imho) would be to extend tiles so it could utilise other views rather than just jsp. This could then leverage the great work Cedric has done on tiles wrt XML definitions and 'extends' definitions. Sorry if this seems like a really dumb/lazy q but how does the .vm get passed to velocity for processing - is this just via a servlet-mapping in web.xml. If so, could tiles not be extended to also pass the appropriate extension to a servlet mapping for processing? (Has anyone run any ideas past Cedric?). I'm not advocating even stronger dependence between the components - as I know you have strong and I think perfectly justifiable views on this - but tiles allowing a different processing engine for a resource could be very powerful. Ok, it could be tiles already does this - and I'm just rambling. I'll have a look again at the tiles code and try some examples before posting again.

I should probably do a how-to, but here's a clip from a Tiles Support thread on the Velocity User list: = Mark de Reeper wrote: #parse(/WEB-INF/templates/vm/htmlheader.vm) table width=100% border=0 tr td#if($header)#parse($header)#end/td /tr tr td#if($body)#parse($body)#end/td /tr tr td#if($footer)#parse($footer)#end/td /tr /table #parse(/WEB-INF/templates/vm/htmlfooter.vm) Then define a template to set the layout and the various bits, this is what is loaded as the main template to parse: #set ($body = /WEB-INF/templates/vm/templatebody.vm) #set ($footer = /WEB-INF/templates/vm/templatefooter.vm) #set ($header = /WEB-INF/templates/vm/templateheader.vm) #parse(/WEB-INF/templates/layouts/layoutHBF.vm) Ted Husted wrote: This is just how the original Struts Template library worked. (Great minds and all that.) You defined a second file to administer the template. This works well enough but it tends to generate a lot of meta-templates that are just used to call other templates. As Slavik pointed out, Tiles extended the template library so that you could express the meta-templates in XML. Instead of forwarding to the glockenspiel.vm template, you can foward to make a reference to say /vm/Glockenspiel and Struts will automatically look for a vmGlockenspiel element, do whatever sets you need, and the forward to the layout. A very neat aspect of Tiles, that we need to adopt for the other Struts configurations, is that one element can extend another. So if you just needed to replace the title on a page, you can extend one element and just override that one set. This makes a *huge* difference in maintenance when you pass the thirty page mark. Until one of us gets around to writing a Tiles tool, I've prototyped what you can do in the Struts config. I've a ViewAction that does the setting. You create the variables to set as Struts ActionForwards and pass their names to ViewAction as ActionMapping parameter. So I have something like this to describe a page: action path=/vm/main/permit/View type=us_ok_deq_wqdata.http.ViewAction validate=false name=permit_select_id parameter=vmTitle,vmChoice,vmMenu,vmBody,vmAction,vmButtonBar forward name=vmTitle path=Permit Detail / forward name=vmChoice path=View / forward name=vmMenu path=/cpu/menu/main.vm / forward name=vmBody path=/cpu/permit/view.vm / forward name=vmAction redirect=false path=/Main / forward name=vmButtonBar path=/cpu/permit/viewMain.vm / /action To render the same page but with a different button bar, I'd just change that forward to include some other template instead. Besides URI's for parse statements, you can also pass any variable you need to create. For example, vmChoice tells the menu which item we are on, so it can dim that one (and leave the rest linked). While we can't extend struts-config elements (yet), the ActionForwards do have a local and global scope. So you can do things like create a global default forward and let that pass through when it doesn't need to be changed. This is done for the Layout. There's a default vmLayout forward which can be overridden by an element if you need to use a different layout. This works fine inside of Struts and will work even better when we get the Struts config to support extended elements like the Tiles config. But, it seems to me that it's something that could also be done outside of Struts and made available to anyone
RE: [OT] Learning Curve Management or Confusions of a Newbie
Hi Jeff, I read with interest your comments on the above. I think Rick Reumann has done a great example recently of a 'walkthrough' which I presume you'll have seen: Struttin' with Struts: http://www.reumann.net/do/struts/main I agree entirely with your comments - I'm still learning some bits of struts myself. What I've found really useful in the past has been Microsoft's Knowledge Base articles which you may/may not have used on msdn.microsoft.com. Of late they seem to have become less relevant as it has been much easier to just view the source with struts and related products - what a great idea: Open Source Software. I've found Vic's basebeans classes really useful also in understanding other complete approaches to building a struts application and I really like Vic's basebeans approach - it has some excellent merits in terms of performance and certainly speed of development. We have *loads* of 'Knowledge Base' articles we have prepared mainly on (Debian) Linux, Tomcat, Struts ( tiles, etc.) and quite a few other (largely unrelated) topics. Most of these are actually on paper at the moment, though. I'm putting together a similar example to Vic (Cekvenich)'s basicPortal but more for the content rather than the approach (the code for this is mainly Vic's). This can be hosted somewhere - on of our servers initially - but with public access in case anybody else is interested. Here is an extract from a previous mail I sent out on 8th November 2002: Sorry to perpetuate something that could be construed to be OT... but I'd like to chip-in with my 2p worth if that's OK. As relatively very new users to Struts we have found getting up-to-speed with Struts more difficult than we originally envisaged - probably due to being used to being spoon-fed over the years and not used-to really grown-up technologies like Struts, i.e. we have considered MVC before but it was easier just to get the job done - MS VB/ASP/.NET makes it very easy to get a solution up-and-running but we have always found we pay for this in maintenance times later! Having now committed to going Struts 1.1 - what we find we're missing are simple, complete and specifically targeted HowTo's or a Knowledge Base of worked examples on specific topics. Yes, javadoc is very useful - source (yippee!) is even more useful, user guide is detailed but has - clearly every possible option and it is not always clear which options we need in the (usually) simple solution that we're attempting to find. OK, google search is useful, apache.struts newsgroup even more useful and other great articles such as IBM Developer Works and other sites, e.g. Cedric's articles on tiles. However - well written it is not always clear to which version they refer and these complete articles are more like mini books and obviously take a significant amount to maintain and can sometimes quickly get out-of-date and cause a great deal of confusion to novices such as we consider ourselves to be. This list has been extremely useful - the replies, to be honest are staggering in their excellent quality. I always feel a bit (honoured and at the same time) distressed that authors (just speaking from limited personal experience) Cedric and Craig (obviously and others) have read and taken time to post a response - these people must be extremely busy just developing the core product to be answering questions that must seem fundamental. OK, I'm sure they don't mind but there must be a better way... We've started compiling internally, for our own use - our own KB articles - to be honest this is just a simple tile template (cheers, Cedric) with areas such as Sensible Title, Summary, Product (struts, tomcat, jikes, debian), Version(s) covered (usually common tile) as far as we can tell, More Information (body text) with file links, Other Resources and References (links to other articles). Ok, not rocket science - but this has been extremely useful to us. I gave up 2 years ago trying to remember everything (anything :-) and this is always my first port-of-call as it's easily searchable ... but this could be extended to comprise summarised information from these lists - OK this would be manual - but honestly how many would we need for simple repeated stuff for Struts = 50-100? e.g. mail from Mark Zeltser (Can forward action point to tiles definition?) - ok this can be got from the user guide, Cedric's article, Wellie Chao's article (IBM), probably from this list in a previous post - has solicited 9 responses. Unsuprisingly this really foxed us for a few hours - we realised in the end we could only do this via an action but a simple howto to cover this and include some info on Global Forwards would answer this question and the potential next one How do I create an action to do this? with an example of it in use would be an excellent searchable resource for everyone and a real jumpstart for anyone just getting-into

RE: BaseBean questions [was] [ANN] Struttin' With Struts beta (newbies esp. welcome)
Maybe you should be doing Vic's labs, Rick ;-
I loved the walkthroughs BTW - it is particularly useful to have worked
examples of various concepts - this can save literally hours by having a
working example - particularly with new bits one may not have used
previously, i.e. all of it is incredibly useful for beginners. It *can* take
a while trying to understand the various options with struts - at least
getting something working is a great starting point. Kudos to you for the
Struttin' With Struts idea *and* implementation. Looking forward to the
next bits :-
I must admit to being a (recently introduced but) great fan of Vic's
basebeans approach - it has greatly simplified getting CRUD working with
struts for me and introduced me to some very neat OO techniques. The code is
minimal - and as with all great ideas - its elegance is in its simplicity.
I'll refrain from trying to answer your question as I may be speaking
out-of-turn - might be better for Vic to answer this direct.

I love the OO approach to your code, I'm just still very confused about
how a simple implementation of a BaseBean would work in calling a DAO to
save itself? In other words, what gets passed to the DAO from the
BaseBean implementation to do the CRUD?
For example in a case where you had:
EmployeeFormBean extends BaseBean
I would take it EmployeeForBean would need to hold user fields such as
firstName, lastName, address, etc with appropriate getter and setters.
How do these fields then get passed to your DAO for the CRUD operations?

RE: TILES - Network Traffic...
Hi Puneet, Sorry for the delay in responding - I've been away for a few days. What you describe is similar to what we did in a web application about 12 months ago - but that was using SPAN... to display/hide the page contents - so in fact all tabs were loaded first and then just displayed when needed. This was using a bit of javascript on the client - the most difficult part was rebuilding the tabs on the client browser - to visibly highlight the page being displayed. This was done by building a HTML string in script and assigning the contents of the string to the innerHTML of a DIV... I guess it may be possible to check if the IFrame has been loaded (i.e. src has been populated) and if not set the src property and set visibility to visible (after setting the non-selected tabs' visibility to hidden). This would allow re-displaying already downloaded tab's contents and downloading on-the-fly new tabs. Already downloaded IFrames would be rendered but hidden. This may work very nicely indeed.

Hi Olivier,
I notice, actually in tiles examples, specifically:

Tiles is a major pita to set up but its amazing how much time
it saves down
the road.
I think its awesome just from the fact that u dont need to worry about
putting all the decorations on a page (nav bar/header/footer
etc) and only
need to worry about the meat and potatoes part.
Aside from using it as a layout manager however, there's a
few other things
that it can be helpful for.
I would suggest going to the main tiles site to see all the
stuff it can
add.
A tiles tag can not be inside a logic:iterate.
It is a very painful limitation.

RE: [TILES] Foxy Tiles Problem
Hi Peter, I'm not sure I fully understand but we're using ... template layout within templates layout? successfully and I think this is necessary for all but the simplest tiles layouts. Indeed, tiles examples have used this mechanism a lot and appears the only way of using layouts within layouts. I'm concerned that run an html:form outside all the shareable and non-shareable tiles will severely limit the true flexibility of tiles as clearly HTML FORM .. cannot be nested and so you would not be able to insert a tile that say asked for one or more input fields with a submit. I guess you could change your global FORM... action= usind javascript to post to a different action but that seems yukky in the extreme. We use this run an html:form outside all the shareable and non-shareable tiles for wizards and this works really nicely as clearly data is entered on one page before posting to the next page. I hope I'm on track so far? All I would ask is that is there a way to avoid the run an html:form outside all the shareable and non-shareable tiles and have a different mechanism for changing pages (sorry haven't seen amazon for a while so do not know their layout) - this would clearly be a problem if you wanted to post values from one page on changing page. Maybe using a A.. may be possible to change pages. Not sure that helps but I've written it now so I'll post it.

I have a web site like Amazon.com that using Tabs to navigate around a set of HTML Form elements. Each Page has a HTML Form that contain lots of HTML Input elements. I have written the JSP in the first phase to be monolithic and now I want to break down the layout to use Tiles. I want to take advantage of the fact, that certain areas of the layout design are shared. Unfortunately I have run in to difficulty because they want a specific design that forces me to run an html:form outside all the shareable and non-shareable tiles. Ideally, I would like to dynamically set the name of the `action' tag of html:form below. I would like to say action=/Main.do and then action=/Shipping.do for a single template layout. How can I do this, using TILES? Otherwise I will have to create template layouts for each tab page. (Yuck) Also is it good practice to have template layout within templates layout? // This is a template layout.jsp !-- Search form -- tiles:insert attribute=customer-search-form / %-- e.g. ``customerSearchPrompt.jsp'' grabs a CRM record from database.

Hi Andy,
The (MS) reference was because this was using the regular expression
syntax
used by Microsoft's VBScript RegEx object and I'm not sure if this is the
correct format for java regular expressions. I think jakarta-oro is a reg
ex
library that is included with struts - but sorry I have no experience with
this - although someone on this group almost certainly will - so might be
worth a separate post - but the example will serve as a good start point.
It
basically means:
\[- string to match begins with [
([ is escaped because it's a delimiter)
\S- match any non-whitespace
[ - (delimiter)
^\[ - stop if you encounter another [
(to trap error with unclosed [] blocks)
] - (delimiter)
* - match any character
\]- ends with ]
(] is escaped because it's a delimiter)
Images would be a different problem - if you look at an RTF file then it
is
quite straightforward to extract the image from the rtf - but each image
would need to be converted in this way or find some way of doing this
on-the-fly - but I'm not aware of any tool to do this! If you have a
limited
number of images, e.g. logos etc. then it would be possible to insert the
converted one of these at the appropriate point. Images begin with
something
like:
{\*\shppict{\pict{\ ... }} with loads of hex digits in-between.
If you have loads of images stored as say gifs or jpgs then you will need
to
find some way of doing this on-the-fly to rtf format.
Hope the above helps a bit more.

Hi Andy,
I've looked through the thread and can't see specifically what you're
trying
to do but we had exactly the same problem and was solved using RTF,
thus:
(this was for submission of documents to a UK government body that
needed
to
be in MS Word .DOC format - they were able to open these documents with
no
problem in Word: edit, print, save etc.).
We used RTF for the document - generated manually in MS Word and
exported
to
a .RTF - and used placeholders to hold active data that was to be
inserted
into the template of format [oTbl.Field] (allowable in RTF - and
replaced
these using (MS) reg ex of format \[\S[^\[]*\]).
This then gave us an RTF format document which was then saved with the
extension .DOC - which MS Word opens with no problem at all. This was in
fact sent to the browser by adding a header content-disposition of
type
attachment; filename=WORD.DOC and also specifying the
ContentType
of
application/rtf. Saving this document saves the document in Word
.DOC
although it is really an RTF.
Not sure it's what you're after but after battling trying to open MS
Word
on
the server - which needs administrator privileges for the user running
the
web app (scary) or using vbscript/javascript in the browser (requires
the
site to be added to IE Trusted Sites) - not ideal.
The solution outlined, using RTF is not dependent on the browser used
and
the above solution is being used to generate around 200-300 (probably
more)

RE: Sell me on tiles
I appreciate you've had lots of replies already - but tiles was the killer feature for us in selecting struts. Please don't misunderstand that struts isn't great anyway - we love it - but the addition of tiles has made developing complex websites a breeze. There is a very outdated first-cut of one of our production sites at: http://www.mortgagesurgery.com/ ... the full production version will be released very soon. This was developed entirely using tiles and would have taken much, much longer without tiles. It's using tiles everywhere - mainly using definitions from tiles-defs.xml. The main menu is a header/body/footer tile with a niceBoxGreen tile inserted that has a further body content - and each menu bar option is a tile - so the hover/onclick code was only written once and then used by inserting 6 tiles with different parameters. The tabbed-frame on the first option was also created using tiles - this would have been a nightmare without tiles - trust me this was first developed in ASP and ASP.NET until I discarded both and looked for something better - and it now uses the very wonderful struts. Also see: http://www.openaction.co.uk/jserv/ ... ok it's just a pretty naff holding page but tiles allowed this to be created in 1 hour. It has a tiles header/body/footer outer definition. A further niceBoxBlue is inserted in the bodyContent that gives the Coming Soon! box and this has a titleString property for the header and a further bodyContent that contains the page with the text. This wouldn't even be possible to do without really inelegant code and jsp includes. I'm not saying these are great examples of what tiles can do - Cedric has some superb portal and other configurable options that really show the power of tiles. My personal view is (and I'm sure someone will disagree!) - with tiles available and so well-integrated into struts - you'd be really missing-out by not using it - even for the simplest of sites. There are loads of examples on tiles - I found Wellie Chao's article (referenced in tiles resources) at the IBM site really helped me learn tiles initially and also has a great justification for using tiles: http://www-106.ibm.com/developerworks/java/library/j-strutstiles.html?loc=j Hue. -Original Message- From: Southard, Don [mailto:[EMAIL PROTECTED]] Sent: 18 February 2003 16:34 To: Struts User Group (E-mail) Subject: Sell me on tiles We are starting a fairly new project using struts.

RE: [OT] RE: Sell me on tiles
;- Actually Opera do supply it as a deb for Linux so we might well give it a try - as all development happens on Debian workstations. I guess it's not supplied as part of Debs as it's not OSS? I remember the problem now... when using TR HEIGHT=100% Opera (probably rightly) allocates 100% of the table - the consequence being the footer drops off the bottom of the browser and you get a scrollbar at any resolution. This doesn't happen in IE or Moz. (Of course I'm not saying IE and Moz are correct to do this). I'm pretty sure the solution is to use another table outside of this one and have yet another nested table - but this is a special case just for Opera. (Ok and w3c compliance, presumably). There are loads of googles on this and just before we get to production we'll deal with it then. After all we have to keep the Opera fans happy - it was my first real browser before I was Mozilla.org'ed. Thanks for your comments. If you don't mind - I appreciate it's very OT - but if you have the answer to the above I'd be very grateful of your input.

Hi Andy, I've looked through the thread and can't see specifically what you're trying to do but we had exactly the same problem and was solved using RTF, thus: (this was for submission of documents to a UK government body that needed to be in MS Word .DOC format - they were able to open these documents with no problem in Word: edit, print, save etc.). We used RTF for the document - generated manually in MS Word and exported to a .RTF - and used placeholders to hold active data that was to be inserted into the template of format [oTbl.Field] (allowable in RTF - and replaced these using (MS) reg ex of format \[\S[^\[]*\]). This then gave us an RTF format document which was then saved with the extension .DOC - which MS Word opens with no problem at all. This was in fact sent to the browser by adding a header content-disposition of type attachment; filename=WORD.DOC and also specifying the ContentType of application/rtf. Saving this document saves the document in Word .DOC although it is really an RTF.

RE: [OT] RE: microsoft .doc struts
Hi Andy,
The (MS) reference was because this was using the regular expression syntax
used by Microsoft's VBScript RegEx object and I'm not sure if this is the
correct format for java regular expressions. I think jakarta-oro is a reg ex
library that is included with struts - but sorry I have no experience with
this - although someone on this group almost certainly will - so might be
worth a separate post - but the example will serve as a good start point. It
basically means:
\[- string to match begins with [
([ is escaped because it's a delimiter)
\S- match any non-whitespace
[ - (delimiter)
^\[ - stop if you encounter another [
(to trap error with unclosed [] blocks)
] - (delimiter)
* - match any character
\]- ends with ]
(] is escaped because it's a delimiter)
Images would be a different problem - if you look at an RTF file then it is
quite straightforward to extract the image from the rtf - but each image
would need to be converted in this way or find some way of doing this
on-the-fly - but I'm not aware of any tool to do this! If you have a limited
number of images, e.g. logos etc. then it would be possible to insert the
converted one of these at the appropriate point. Images begin with something
like:
{\*\shppict{\pict{\ ... }} with loads of hex digits in-between.
If you have loads of images stored as say gifs or jpgs then you will need to
find some way of doing this on-the-fly to rtf format.
Hope the above helps a bit more.
H.

more research as i am yet to understand regular expressions, and how to

RE: Tiles Portal
Hi Jay, I've not actually done exactly what you're asking, however it would seem to me quite straightforward to determine the url that was used to access the site using: String cURL = request.getParameter(url); You could then use string extraction techniques to get the portion of the URL and I would guess it would be easier to store this in session scope. I would guess that the colours for the web site could be determined by loading a specific CSS Style Sheet that would be determined by examining the value stored in session scope. The tile templates could be determined by say concatenating a code onto the template or looking in a directory for all tile templates for that company. I'm pretty sure this would not work with tile definitions defined in tiles-defs.xml so you may need to restrict yourself to definitions stored in JSP files.

Yes, we were using Tiles (just) before Struts - and then went to use Struts+Tiles. The only aspect AFAIK that will not be available is using Tiles as Struts forwards. There was also a thread about using Tiles with Struts 1.0.2 - try ng apache.struts on news server news.basebeans.net and look for title: Tiles and Struts 1.0.2?, the most relevant answer seems to be: The Tiles site (http://www.lifl.fr/~dumoulin/tiles/) is the place to go.

[OT] RE: Entire Struts Mail Archive
Sorry to perpetuate something that could be construed to be OT... but I'd like to chip-in with my 2p worth if that's OK. As relatively very new users to Struts we have found getting up-to-speed with Struts more difficult than we originally envisaged - probably due to being used to being spoon-fed over the years and not used-to really grown-up technologies like Struts, i.e. we have considered MVC before but it was easier just to get the job done - MS VB/ASP/.NET makes it very easy to get a solution up-and-running but we have always found we pay for this in maintenance times later! Having now committed to going Struts 1.1 - what we find we're missing are simple, complete and specifically targeted HowTo's or a Knowledge Base of worked examples on specific topics. Yes, javadoc is very useful - source (yippee!) is even more useful, user guide is detailed but has - clearly every possible option and it is not always clear which options we need in the (usually) simple solution that we're attempting to find. OK, google search is useful, apache.struts newsgroup even more useful and other great articles such as IBM Developer Works and other sites, e.g. Cedric's articles on tiles. However - well written it is not always clear to which version they refer and these complete articles are more like mini books and obviously take a significant amount to maintain and can sometimes quickly get out-of-date and cause a great deal of confusion to novices such as we consider ourselves to be. This list has been extremely useful - the replies, to be honest are staggering in their excellent quality. I always feel a bit (honoured and at the same time) distressed that authors (just speaking from limited personal experience) Cedric and Craig (obviously and others) have read and taken time to post a response - these people must be extremely busy just developing the core product to be answering questions that must seem fundamental. OK, I'm sure they don't mind but there must be a better way... We've started compiling internally, for our own use - our own KB articles - to be honest this is just a simple tile template (cheers, Cedric) with areas such as Sensible Title, Summary, Product (struts, tomcat, jikes, debian), Version(s) covered (usually common tile) as far as we can tell, More Information (body text) with file links, Other Resources and References (links to other articles). Ok, not rocket science - but this has been extremely useful to us. I gave up 2 years ago trying to remember everything (anything :-) and this is always my first port-of-call as it's easily searchable ... but this could be extended to comprise summarised information from these lists - OK this would be manual - but honestly how many would we need for simple repeated stuff for Struts = 50-100? e.g. mail from Mark Zeltser (Can forward action point to tiles definition?) - ok this can be got from the user guide, Cedric's article, Wellie Chao's article (IBM), probably from this list in a previous post - has solicited 9 responses. Unsuprisingly this really foxed us for a few hours - we realised in the end we could only do this via an action but a simple howto to cover this and include some info on Global Forwards would answer this question and the potential next one How do I create an action to do this? with an example of it in use would be an excellent searchable resource for everyone and a real jumpstart for anyone just getting-into tiles. The questions would really be ... where could it be hosted, any articles would need to be vetted but where better than this list, who decides on which howtos to write. OK, resources like theserverside (and many others) already does this kind of thing but most I've read are more like mini books again - nice to read - I've printed 5,000 sheets of paper (to read in the bath) to get up-to-speed over the last 6 months - hence our reason for compiling our own KB. Ok, I've probably bored you now - any comments or anyone else have any comments?

[Tiles] Tiles vs. Custom Tag - anyone have a view?
We've been using tiles extensively in an app and it has been extremely effective - as one might expect for including tiles of information on a page and consolidating standard layout into templates - however I'm concerned that we might be going too far in its use... and using it where we might otherwise have used a custom tag: For a single img that is used extensively in an app that has mouseover/out/down behaviour, e.g. (in HTML - lots of code left out deliberately here): img src=/images/navigation/right.gif onmouseover=javascript:setImg(this,'/images/right_hot.gif') onmousedown=javascript:setImg(this,'/images/right_hot_down.gif') onmouseout=javascript:setImg(this,'/images/right.gif') This can be much simplified to including a tile of just this control: tiles:insert template=/tiles-components/controls/imgactive.jsp tiles:put imgName=/images/right / /tiles:insert The alternative would be a custom tag, e.g: sshtml:imgactive imgName=/images/navigation/right / Which is obviously much easier to include but so much less flexible - requiring editing tag handler java code to edit html - and all of the issues this entails - tiles allows us to edit the html in a nice easy jsp. This is much more effective for complete chunks of html and has saved huge amounts of time for large composite controls that we have everywhere. I feel it is neater but am concerned we are introducing too much processing for just producing the html for the control - does anyone else have a view on this ... any comments appreciated (even Stupid Idea if this is).

RE: WebLogic/Struts/JSP performance woes...
I do not think even Client/Server could do this nicely. Have you ever seen anyone else put out an application in any design that has 2000 rows? In a word, Yes. We had a client - system went live over 2 years ago using IIS on an Intranet as it happens. Client had 600 branches UK wide, with = 10 clients per branch (and in some cases many more than this) and wanted to see - on one page top (usually) 20 clients per branch with various metrics per client. No, they didn't want paging. No, they didn't want a smaller list (on this page). Yes - they wanted to see all records and then drill-down on the ones that interested them in a new browser window. We had to find a way to giving the customer what they had asked for or tell them it was not _technically_ feasible. The browser was known: IE5.5; it was always only ever accessed from a 100MBit LAN; the users were using powerful workstations. We used hints on the query to return top rows quickly - the metrics were calculated on data loading into the database - with incremental fetching and used fixed-width table to allow progresive fetching. Problem solved .. page was starting to render after about 3-4s and took about 40s to render fully - they could start viewing the data as soon as it started loading. Result: happy customer. What JDBC driver lets you stream data over, before the resultset/rowset has finished retreving? Or is the data fast, just the rendering is slow? I don't know if JDBC can do incremental fetching - even so retrieving 1,600 rows should not take that long if the query is sensibly written and has useful indexes available.

RE: WebLogic/Struts/JSP performance woes...
Hi Davide,
I'm pretty sure what you're seeing is browser-related, if you are flushing
the output periodically from the server: Nat and James have already stated,
tables will _likely_ not render until the width of all columns are known ...
sometimes the table _will_ progressively render and then shift about as
wider columns are required in later rows. (You can sometimes check this by
waiting a short while so the table has partly downloading and pressing
stop which usually causes what has been downloaded to display). The actual
behaviour tends to be browser-specific and from our tests with IE (5.01SP2)
also seemed inconsistent. This is how we got a very satisfatory result:
I'm not sure if this is IE-only behaviour so forgive me if this does not
apply to other browsers - but this may serve as a starting point for
investigation. CSS2 which I presume is Cascade Style Sheets V2 supports the
concept of fixed-width tables, from:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnie50/html
/cheatsheet.asp (Fixed Width Tables section):
HTML tables are normally relatively slow to appear, since browsers
calculate the size of each cell in the table before beginning to draw it.
When you set the CSS2 table-layout property to FIXED, the browser uses the
column-width and row-height information in the first row of the table to lay
out the table immediately. Fixed tables render progressively, resulting in a
significant speed improvement.
We had to use this in an Intranet app that was producing huge tables, i.e.
sometimes 30,000 rows. And, yes, they did ...really, really want to see
all the data... (accountants). Utilising fixed-width tables produced a
_significant_ increase in *perceived* speed of page download. The following
excerpt was taken from:
http://msdn.microsoft.com/workshop/author/tables/tables_overview.asp#layout
The following example shows the use of the Cascading Style Sheets (CSS)
attribute, table-layout, to fix the table layout, resulting in faster
rendering of the table. Note that the widths need not be set on the TABLE
and COL objects. When the width is not specified, the browser looks to the
contents of the first row's cells to fix the column widths and,
consequently, the table width.
TABLE STYLE=table-layout:fixed WIDTH=600
COL WIDTH=100COL WIDTH=300COL WIDTH=200
TR HEIGHT=20
TD.../TDTD.../TDTD.../TD
/TR
:
/TABLE
The performance gains are significant, especially for large tables. Because
the browser does not need to parse through the table once simply to lay it
out, the table rows can start to render immediately.
HTH,
Hue.

Subject: RE: WebLogic/Struts/JSP performance woes...
Yes...
Again, what's strange is that during my extensive tests/experiments/hair
pulling sessions I've actually seen this type of code work (using tables) -
There's still a small lag between when the page clears and when the output
starts to appear, but output definately starts to appear before the server
is done:
for (int i = 0; i myCollection.size(); i++) {
out.print(/tr);
out.print(td);
out.print(myData);
out.print(/td);
out.print(/tr);
out.flush();
}
Although by that point, the page that I was using to perform the tests had
been tinkered with extensively, so not all the table tags may have been
there which might have allowed the browser to render the output sooner. What
other tags would you suggest? divs?
Cheers...
