Changing Form Target in Action?
Hi all
I have the following problem:
I have a button on my form that uses javascript to change to form target
before submitting because I'm exporting an RTF generated in my action to the
new browser, as follows
html:submit property=exportFlag
onclick=set('export');setFormTarget('_export')
disabled=falseCreate Graph (Popup)/html:submit
function setFormTarget(newTarget){
document.forms[0].target=newTarget;
}
The thing is I want to be able to use the validate() method in my Form
object and return to the ORIGINAL browser if an error is encountered...
so is there anything I can do within the action to affect that?
Thanks

Re: Changing Form Target in Action?
Hmm.
I suppose it would be easier to just do the validation in JavaScript... but
I **really** dont want to. It just seems inconsistent.
So there's no way to change what browser the validate() returns to once
I've submitted the form and I'm in the validate() method? Some attribute on
the request perhaps? I mean the request has to know where it's forwarding
to, right?

When I've had to do something like this in the past, I didn't
actually change the target, but rather caused the response page to
use the new target as part of its page loading. That is, the
response page would have an onload handler which would load the
necessary content in a new target.
If your new target is a new window, pop-up blockers may foil this,
and of course, you'll have to make sure to preserve any relevant
state, since the onload handler will initiate a separate request.
Can you make that work?

Oh this one sounds good. I'm not sure how I'd actually DO that though.. can
you provide more info? All my pages are tiles definitions right now. How
would I cause the response page to use the new target (conditionally)?

Creating a standard page to handle Error 500
Hey all I recently added the following to my JSP pages to force them not to be cached: % response.setHeader(Pragma,no-cache);% % response.setHeader(Cache-Control,no-store);% % response.setDateHeader(Expires,-1);% the result is that if the user hits back then reload they get an error 500. How can I create a page that will handle any error 500 that comes up? Essentially, I just want to display a message that tells the user to re-login.. thoughts? -- -Dave [EMAIL PROTECTED]

Re: Redisplaying Information
I believe you can do this by setting the scope of the form bean associated with the form containing your field to session, which also means you need to reset() it when you're done. like this: action path=/SICAction name=sicForm scope=session input=page.portfolio type=com.company.struts.SICAction forward name=success path=/myPage.jsp redirect=true / /action On 5/26/05, Andrew Thorell [EMAIL PROTECTED] wrote: I know html:password has a redisplay option.

Wendy, Removing tiles from the equation has done the trick.

What is the root cause of the error 500? Take the error-page out and look at the stack trace. Ignoring any ServletExceptions, what's the _real_ problem here? Configure THAT exception in struts-config.xml with an exception tag, and you will be able to use a tiles definition. Then create a simple html or jsp page that fits with your site design, put a generic error message on it, and use that for the location of your error code 500 in web.xml. IMO, you should never get as far as an error code 500 during normal operations. You know what kind of exceptions your code can throw, deal with those in struts-config.xml. It's the unchecked exceptions that are going to make it all the way out to the container, and the web.xml config is a last ditch effort to make sure the user does not see a stack trace. -- Wendy Smoak - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- -Dave [EMAIL PROTECTED]

http://www.niallp.pwp.blueyonder.co.uk/HelpTagsErrorsAndMessages.html VERY
helpful ant informative. I've refactored my application (yes it's midnight
in NY) to REMOVE all ActionError references (leavinf the ActionErrors in the
validate() as you recommend.
I have a question though
This opens up the possibility of having errors and messages both stored
using saveerrors( request, ActionMessages) but what I'm wondering what
method you'd recommend for separating them?
I'm using this to display my errors in my jsp:
html-el:messages id=msg message=false
c:out value=${msg}/
/html-el:messages
but it wouls seem to make more sense to have perhaps two areas in my JSP,
one reserved for errors and one for messages, like this:
html-el:messages id=msg message=false
c:out value=${msg}/
/html-el:messages
html-el:messages id=errors message=false
c:out value=${errors}/
/html-el:messages
it would seem that saveErrors() saves everything unser the msg key by
default.
Is there any way do override that behavior to store it under a key that
makes more sense (i.e. I'm saving errors under the key=msg which seems
sketchy)
I understand that I can do this:
ActionMessages am = new ActionMessages();
am.add( ActionMessages.GLOBAL_MESSAGE,
new ActionMessage( msg.warning ) );
request.setAttribute(warnings, am);
but it FEELS like a workaround
thoughts?

Re: Opening a Form in a New Window - Help!
hey there
What meant was that I wanted to open a new browser that had these options
set:
window.height=400;
window.width=300;
window.status=yes;
window.toolbar=no;
window.menubar=no;
window.location=no;
so that it isnt just another same size browser with tiny help text in it.

Hello,
In order to set those options you will have to use Javascript. The
target attribute is a fairly dumb animal in that it just opens said
target with the location you specify. Anything more requires scripting.
I wasn't clear on what you meant by:

Specifically, the part about submitting a struts form to said window...
can you explain that a different way because I'm not sure what your

Re: Best practice for redirecting on session timeout?

That's easy, just drop this in all of your JSPs (preferrably via an

You should be handling invalid/expired session state in your application

managing sessions from your actions, CMS, or some other service outside

the conatiner, such as a product like SiteMinder by Netegrity.
This will _force_ the browser to do a refresh of the page after 1200
seconds
(20 minutes), which will allow your app to handle the request (from a
now
expired session) the same as it would if the user had initiated the
request

Re: Opening a NEW browser for a 2nd content type from an action

This is pretty straightforward. In browser a, you have a button that

The code would look like this:
html:form action=/exportToPdf.do target=_NEW

/html
When the user clicks on the button, the action exportToPdf.do opens an
ServletOutputStream and writes whatever you want. The headers are also
set to the content-type you want and the format you want (inline or

Good point Aladin...
However, I would take this a step further...
in pre-1.3 Struts, you might not want to implement your own RP for various
reasons, so I would suggest doing this in a filter instead... Same benefit
as modifying the RP, but doesn't touch Struts code and is also more
portable... should you ever want to not use Struts for some reason, you
don't have to worry about re-implementing your auth check.
In 1.3, you could probably make a good argument for modifying the RP
chain, certainly that's what your meant to be able to do!, but I think the
same good reasons for using a filter would still apply there.

Hi,
This approach would work as well. I just think that if you're going to

this in struts, it's better to do it in the RequestProcessor. Why?
Assume that you are using the forward action defined in struts. If my
session has timedout and I click on a link that uses the forward action,
I
will still see the page. This is because your BaseAction is never
called.
On the other hand, if you had checked the request in the
RequestProcessor, I would have been blocked. This is because *ALL*
actions pass through the RequestProcessor... even the struts-defined
ones.
That's the approach I would use (RequestProcessor approach) if my
container didn't support filters.

One things though, I'll have to set the target conditionally,
only when
the user clicks PDF or EXCEL since I dont **always** want it
opening a
new window...
function setTarget(target) {
document.forms[0].target=target;
}

Hi Dave,
This is pretty straightforward. In browser a, you have a
button that
says:
Export to PDF
The code would look like this:
html:form action=/exportToPdf.do target=_NEW
submit name=export value=Export to PDF
/html
When the user clicks on the button, the action exportToPdf.do
opens an
ServletOutputStream and writes whatever you want. The headers
are also
set to the content-type you want and the format you want (inline or
attachment).

Hey all
is it possible to forme my struts app to open up a second browser
window
for
the purpose of streaming a different content type (like a pdf
file)
into
it
while maintaining the page in the original browser?
Essentially, I have a nicely rendered HTML report in browser
a and
when
the user clicks export to PDF or export to excel I want a NEW
browser
to
pop up into which I will send the response with the headerType
set to
the
appropriate type.
the generation of the XL and PDF is handled for me, but the
app flow
is
where Im foggy.
anyone done this?

html-el:img question
Hey all
I've got the followiong directory structure for my web-app
C:\Builds\riskGrid\WebRoot\jsp (all JSP's are here)
C:\Builds\riskGrid\WebRoot\jsp\images (all images)
This is the image code (in a JSP in the jsp directory) that results in the
image not being found. What am I missing?? I cant have an absolute URL for
obvious reasons.
(note everything else is working, the link, the submit, etc.)

Re: html-el:img question
Interesting twist, when I add in html:base/ it gets translated into this:
base href=http://localhost:8080/myApp/jsp/layouts/siteLayout.jsp;
So, does that mean the base location is the layouts dir? Obviously I'm
using Tiles in this app.
Thoughts?

Re: html-el:img question
The full img tag includes some el tags which werent coming out properly with
a normal img tag :( I tried that first :)
the URL when this page is up is :
http://localhost:8080/myApp/portfolio.action but the base href is:
base href=http://localhost:8080/myApp/jsp/layouts/siteLayout.jsp;
html-el:img src=../jsp/images/portGraph .gif

how can I embed the above el stuff in a notmal img tag, and also within a JS
call?

What is the URL in the browser window when it's trying to load the image?
Images are requested separately by the browser after the page is loaded.
The URL for the image needs to be relative to the page the browser
thinks
it loaded, not the location of the JSP files.
BTW, it looks like a plain old HTML img src=... tag would work fine
here, why suffer the overhead of a taglib when there is no dynamic
content?

Re: Losing request attributes after validate()
Right. What I want is to pre-populate text fields if the user id editing
or set it to if the user is creating a new thing.
I think what I'll settle on is making the portfolioName request attribute
a session attribute instead, then in the Save() methos, execute a
myForm.reset()
Is that fairly typical? Is there a better way to achive my goal of
prepopulating fields that exist? I guess I assumed that they'd be populated
but be linked to the form bean assigned to the form.
Sigh.
I feel like there's just a small bit of understanding I'l lacking here

check where this object is stored, in what scope. You are right, if
this object has request or page scope, then it will be wiped out after

This is how Spring's RedirectView (or ViewRedirect? whatever) works.
They have notion of model which is usually a Map. You stuff your
data in it, and it is appended automatically as a payload to
redirected request. Struts does not do this.
If you had Struts appending all form data to the redirected request,
your would be able to use the page only within a strict sequence of
requests. If you jumped out from the page and browse somewhere else,
you lose request data. If then you navigate to your page through
browser navigation bar, you would see that you form is empty (at best.
At worst, you get validation error).
Spring transfers viewstate in the request, just like
ASP.NEThttp://ASP.NET.
I do not
think this is a good idea.
I think that it is much more flexible to pass ID of an object that you
want to display, in the redirected request. Then your output action
would load this object from the database (better from the RAM cache)
and display it. Thus, the action would not care how it was called:
directly, indirectly or through redirect. It just receives object ID
in the request, loads object, fills out the form, and shows JSP.
Pretty straightforward.
Or, instead of fiddling with redirection request, just set
scope=session in your action element in struts-config.xml. Then
form bean will retain all values for you.

If you want to keep redirect=true (I personally prefer redirects for

your form.
This should not work in other places. Maybe your other forms have
session scope or somehow browser thinks that it can cache those pages?

It will not be populated. You redirect to the page, that is, you
reload the page from the server using empty GET request with no query
parameters. Struts cannot populate your form bean since there is no
input data. So it just shows you JSP using current form field values.
If your form has request scope, it is recreated for each request, so
there are no values in it.
Do not use hidden fields. You started well using redirection to the
View ;-) Just change scope of your form to session, and it will
retain values for you. But now you would have to clean unneeded values
in the reset() method. It is a bit of a hassle, but it works better
for an end user, and you do not need to pass viewstate in hidden HTML
fields.

Re: a Form with different actions actions
question:
Does this tip apply to the latest version of Struts? I'm using V1.2.4
and I notived this tip references the perform() method which as far
as I know is deprecated.
I implemented this as it recommends, setting parameter=dispatch in
the ActionMapping, but the methods I've created (with the same
signature as the execute() method arent being called,
for example: my report submit button html is now
html:submit property=runReportFlag onclick=set('report');Run
Report/html:submit
but the report method isnt being called

I have a large page with a form on it that I need to submit to
diffferent actions depending on that the user clicks.
For example, I have on this page
0. a list of items the user can select 1--n of (using checkboxes)
1. a list of graph types, with a graph chosen now button (user
chooses things from item #0 above)
2. a list of reports, with a report chosen now button (user chooses
things from item #0 above)
3. a combine selected buttons (again user chooses things from item #0
above)
4. a create new button
Essentially I may need to access some or ALL of the form fields seen
on the page regardless of which path the user takes, so I assume that
means one big form.
the problem is I want to submit to graphAction for graphs or
reportAction for reports or combineAction etc.
how is this kind of thing normally handled? I have simple forms that
have obvious attribures but this feels different somehow.
thoughts?

html:multibox nested within a c:forEach Help!
Hi all
I have the following, with the goal being to allow the user to select
multiple portfolios, which I can then access in the action class.
JSP:
c:forEach var=portfolio items=${userPortfolios}
html:multibox value= c:out value='${portfolio.portfolioName}'/
property=userPortfolio /
c:out value=${portfolio.portfolioName}/br
/c:forEach
this prints out a checkbox, then thename of the current portfolio from
the userPortfolios collection.
The problem is that in the rendered HTML the portfolioName is not
being printed, only the following (from log.info in the Action Class)
user selected portfolioID=c:out value='${portfolio.portfolioName}'/
the Question is:
Should I be using the c:forEach here or would I have more luck using
the Struts logic:iterate tag would they play more nicely
together?

Also
if I'm using the Struts-EL version of the tags do I simply REMOVE the
references to the old struts tags, or is it proper for them to
coexist? I assume they ca coexist since not all of them have been
ported.

Dispatch Action Strangeness
Hi there
I thought I'd break this into its own thread. I'm trying to implement
a DispatchAction as discussed by Ted Husted here --
http://husted.com/struts/tips/002.html
I have done the following
1. changed the html:submit to the following (along with the necassary
javascript)
html:submit property=runGraphFlag onclick=set('graph');Run
Graph/html:submit
2. Created a graph method on the Action class with the same
signature at the execute() on the action
however the graph method isn't getting called.
My Action class still extends Action should it inherit
DispatchAction instead? What am I missing?

To: [EMAIL PROTECTED] David, I think I replied to this, but I released a more generalized version of the two reloadable message resources on sourceforge. (struts apps) The main improvements here are ease of development of new types of message resources. (I have not moved this over to commons-resources as the superclasses yet by the way so it is workable with struts 1.2x) Mainly now, to implement a reloadable message resource you subclass my BaseReloadableMessageResource and supply 2 methods 1) parseConfig(...) which will know what to do with the config passed from the factory. 2) getMessagesAsProperties() which returns a properties file containing all the messages for a particular locale. This would make it rather simple for you to partition messages between a DB and a properties file and you can enforce whatever ordering you desire. (i.e. all general messages come from the DB which can be changed by admins or whatever, and error messages come from a properties file so that the replacement arguments aren't mucked up) or vice versa or whatever. All of the caching/reloading, is determined by a timeout that can either be hardcoded and supplied to the superclass, or can be a part of the configuration. To load from different sources would be relatively simple, you devise some type of configuration that you can parse. And then load the messages from the appropriate resource type (file,db,etc) based on your scheme. You can grab the source or binary from the sourceforge site at: http://sourceforge.net/projects/struts/ The files are in reloadable message resources.

For instance I created a DBMessageResources class and factory (I can send them to you if you want a quick example of how to do these things. They don't merge two files but it might give you an idea on where to go) At any rate in mine I expect to get three things from the MR config 1) the JNDI Datasource name, 2) the sql to use to retrieve the value given a key, 3) a timeout for my cache. So my message-resources looks like this: message-resources factory=org.homedns.afogleson.messageresources.DBMessageResourcesFactor y parameter=java:comp/env/jdbc/myusersDS,SELECT value from Messages where locale=? and messagekey=?,30 null=false / As you can see there is no need to have your classes exist in o.a.s.util or any particular package in fact.

Re: [OT: JSTL] Re: c:forEach for an object that extends ArrayList in Application **and** Session
Hey
That totally makes sense, and I definitely see hot to iterate through
a collection of Strings or other straightforward things, but what I'm
confused about is that my PortfolioBeanCollection (extends ArrayList)
contains objects of type PortfolioBean which in turn contain the
attribute I'm trying to display..so the PortfolioBean itself has no
explicit name to which I can refer...
so I really want to do something like
PortfolioBeanCollection.PortfolioBean.portfolioName
normally, I'd just loop through the PortfolioBeanCollection casting
the resulting Object into a PortfolioBean then calling the
getPortfolioName() method on the bean
The examples I'be found deal more with simple Collections of Strings,
ints, etc. where you might have a collection of teachers for example
and want to print out the firstName attribute of each... whereas my
example has another later.
I might be babbling. Does that make sense?

Of course--you have to tell the c:out... tag a) what bean to get the
property from and b) what property to display. When you say c:forEach
items=${userPortfolios}... you are telling c:forEach what collection
to use for the iteration. When you say c:forEach var=portfolio...
you are creating a variable you can use in other JSTL tags--in essence
naming each portfolio bean portfolio for the purposes of JSTL.
But you still have to tell c:out... what bean and what property,
otherwise how would it know what to print? When you just say c:out
value=${portfolioName}/ it's looking for an application, session,
request, or page scoped attribute named portfolioName. Without the
prepended portfolio it doesn't know that the property portfolioName
is associated with a bean created through the c:forEach iterator.
I'd recommend checking out some very basic JSTL docs to get a feel for
how JSTL works:
http://www.onjava.com/pub/a/onjava/2002/08/14/jstl1.html
http://www.onjava.com/pub/a/onjava/2002/09/11/jstl2.html

(Wouldn't it have been quicker to just but the property name in your
code and see if it worked?)

so I really want to do something like
PortfolioBeanCollection.PortfolioBean.portfolioName
normally, I'd just loop through the PortfolioBeanCollection casting
the resulting Object into a PortfolioBean then calling the
getPortfolioName() method on the bean
The examples I'be found deal more with simple Collections of Strings,
ints, etc. where you might have a collection of teachers for example
and want to print out the firstName attribute of each... whereas my
example has another later.
I might be babbling. Does that make sense?

Of course--you have to tell the c:out... tag a) what bean to get the
property from and b) what property to display. When you say c:forEach
items=${userPortfolios}... you are telling c:forEach what collection
to use for the iteration. When you say c:forEach var=portfolio...
you are creating a variable you can use in other JSTL tags--in essence
naming each portfolio bean portfolio for the purposes of JSTL.
But you still have to tell c:out... what bean and what property,
otherwise how would it know what to print? When you just say c:out
value=${portfolioName}/ it's looking for an application, session,
request, or page scoped attribute named portfolioName. Without the
prepended portfolio it doesn't know that the property portfolioName
is associated with a bean created through the c:forEach iterator.
I'd recommend checking out some very basic JSTL docs to get a feel for
how JSTL works:
http://www.onjava.com/pub/a/onjava/2002/08/14/jstl1.html
http://www.onjava.com/pub/a/onjava/2002/09/11/jstl2.html

You don't need to cast in JSTL; JSTL does the Right Thing.
You give it a collection ('items' attribute, in your case a
PortfolioBeanCollection, which is a collection, regardless of whatever
additional functionality you've given it), a name to call each object in
the iteration ('var' attribute, say you call it portfolio), and go.
The c:out tag says Oh, you want the 'portfolio.portfolioName' to print
out, tries to call getPortfolioName() on whatever object you've given
it (hopefully a PortfolioBean, otherwise it will throw an exception),
and displays the results.
I don't think I can explain it any differently.
Good luck!

Error Messages from the Database - Simple method?
Hi all I have a similar need to a topic entitled Load Message Resources from DB??? but only for ERROR messages, and quite honestly, I want the simplest approach possible. since my Error Messages and my other test fields currently share ApplicationResources.properties I'm a little trapped though, and that's fine because I want it **totally*** transparent from the JSP tag My current vision is this: I will have a simple table as follows appliction_errors error_label - varchar(25) error_text - varchar(255) I will build a service within a plug-in to retrieve all of the error messages from the database and replace the proprtties bundle that struts loads. My questions are: 1. Where does stuts actually load up the message resources from the file into memory 2. What is the name and type of the variable (to make it transparent to the JSP tag 3. is it possible to just load up a new object and **replace** the one that struts creatd with mine? if not, what am I missing? -- -Dave [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I'm glad you brought that up because I didn't think of it, and wouldn't have until after someone noticed it :) I don't think there is anything that can be done about that, at least not in the case where you redirect to a JSP. If you redirect to an Action Mapping (even if it's just an ActionForward), then sure, the setup could still work there. But redirect to a JSP I don't see a way to make it work. On your other point... I'm actually thinking about allowing the setup elements to be at the mapping level and/or the forward level. The idea being that there may be times you want to do some particular setup functions regadless of which forward is choosen, and other times where you want to do specific setups for specific forwards only. I'm thinking that each setup element you add to a forward can specify whether to process any mapping elements IN ADDITION to those of the forward, or don't use the mapping elements. For example: action path=myAction type=com.omnytex.actions.MyAction setupItem class=com.omnytex.setup.MyActionSetup method=setupMethod1 / forward name=defaultForward path=page1.jsp setupItem class=com.omnytex.setup.MyDefaultSetup method=defSetup1 / /forward /action In this case, when the defaultForward is selected, MyActionSetup.setupMethod1() would be called, followed by MyDefaultSetup.defSetup1(). But, in this case: action path=myAction type=com.omnytex.actions.MyAction setupItem class=com.omnytex.setup.MyActionSetup method=setupMethod1 / forward name=defaultForward path=page1.jsp setupItem class=com.omnytex.setup.MyDefaultSetup method=defSetup1 additive=false / /forward /action ...only MyDefaultSetup.defSetup1() would be executed when defaultForward is selected. Also, I think ideally I'd make the setupItems attached to the mapping executed BEFORE the Action's execute() is called, but clearly the forward-level items would have to execute AFTER execute() completes. I think that gives even a bit more flexibility to it. I'm making this up as I go, so feel free to comment :) -- Frank W. Zammetti Founder and Chief Software Architect [Message truncated.

If you get a login dialog box, as opposed to a login web page, you are probably using HTTP BASIC authentication. If so, the browser remembers the login and automatically sends it to the app with each request, which will log the user in again if they revisit a page after logging out. FORM-based authentication does not have this issue. So one resolution would be to switch to form-based authentication.

Hi,
Can anyone tell me if there is an easy way to put information
(required to populate drop down boxes using data from a db) in to the
request, without having to write a setup Action for each page as is
done here: http://www.reumann.net/struts/lesson2/step9.do .
I started reading a bunch of these threads in reply to the above and I
do think that I'm seeing a trend of over-complification here (yea, made
up word:). I do like the concept that JSF takes, but from some of the
posts I've read, some are complaining about JSF being too page-centric.
Personally I like the page-centric approach and find that it fits the
mold of how typical web apps work. I'd say 99% of the time people use
Struts in a page-centric manner.
Sure you can create a ton of cool ways to handle the setup of Lists into
scope, but I still find it very simple to have in my Dispatch Action a
simple prep() method that handles this.
(The above mentioned SetUp Action in the article was because I didn't
want to introduce a dispatch action at that point, but look at the
http://reumann.net/struts/articles/request_lists.jsp article for more
specifics on how I'd do it using Struts 1.1 and a simple Dispatch Action).
So to summarize typically I'd have
//:SomeDispatchAction
update(..) {
//do stuff
prep(request);
//return forward
}
prep(Request request) {
request.setAttribute(yourList, service.getYourList() );
}
The only time the above is annoying is if you happen to use your update
dispatch method from several different places and your resulting forward
can go to many different pages (not all of which would need the list
placed in request scope.) (Even if you end up going to different pages
from reusing the above Dispatch update method, the worst case scenario
is that you'd typically have a few extra things stuffed into the
request. Yes, if logic is way different you could need to use different
lists with the same name, etc.. but again how common is this? I still
tend to think it's best to solve and code for the 90% rule.)
And although many have proposed nice ideas one of the problems is as
Leon mentioned:
I find it hard enough to manage all the config files I have to manage
right now (struts-config, resources, tiles-definitions, factories, and
so on), I would be the last one to introduce one more.
And the above point is the exact problem with some of the solutions. And
yes Tak I have looked at OzStruts briefly and to me it overcomplicates
things because it's just one more thing a developer needs to learn, when
the standard practices solve 90% of the problems.
To the initial poster (Ben), I'd opt for the simple prep() method unless
it doesn't meet your needs. Another benefit is if someone has to look at
the code, it's easy to find what is going on. Nothing to me is more
frustrating than working on someone's application and trying to figure
out what configuration file is injecting what where and how, or what pre
and post operations are taking place that are setup somewhere else.
Sometimes these solutions are needed, I just don't think for the vast
majority of cases they are.

JSTL c:if question
a little off topic but..
I have a variable (a string named mode) in request scope and I want
to display something conditionally in the JSP. Right now, I have the
following, which doesnt work. The error is
2: Illegal scope attribute without var in c:if tag.
What am I doing wrong?
c:if test=${mode}=='a' scope=request
first thing
/c:if
c:if test=${mode}=='b' scope=request
second thing
/c:if

Tiles - a reality check (contains many details) - Am I using this thing right?
Hi all I'm slowly figuring out the basics of Tiles, and I feel like its a good solution for my application. I want to make sure before I get to far that I'm thinking about things the right way. I have 1. a login page with a header, body and footer 2. Application itself which will contain a Header, Navigation, Body and Footer (same Header, and Footer as the login page). I have created the following directory structure ans JSP layout under my brand new shiny Struts 1.1 web application under the WebRoot Directory \WebRoot \WebRoot\WEB-INF \WebRoot\WEB-INF\tiles-defs.xml (listed below) \WebRoot\jsp \WebRoot\jsp\images \WebRoot\jsp\layouts \WebRoot\jsp\layouts\loginLayout.jsp \WebRoot\jsp\layouts\siteLayout.jsp \WebRoot\jsp\tiles \WebRoot\jsp\tiles\header.jsp (not full html page) \WebRoot\jsp\tiles\footer.jsp \WebRoot\jsp\tiles\navigation.jsp \WebRoot\jsp\loginBody.jsp \WebRoot\jsp\appPageBody.jsp Explanation: \layouts contains my JSP Layouts for the different parts of the app \tiles contains my reusable areas in the app (not complete html pages) \jsp contains the different body jsp files My question is : Is this a typical way to arrange a generic Tiles application? the problem come in when I try to use definition inheritance in the tiles-defs.xml file.

Re: Tiles - a reality check (contains many details) - Am I using this thing right?
Hi again - a follow up question. When using tiles this way, does this mean that any forward I define in my struts-config.xml should be a valid Tiles Definition? Would that then imply that every page in my application is specified by a tiles Definition, and that's how I GET to any given page? Further, assuming all application pages use the Header/Nav/Body/Footer layout (called siteLayout) would there then just be one body page instead of what might be thought of as page in the application, that then gets included into a layout? example: I want to create a Profile Editing page, so I create profileEditBody.jsp and a NEW definition in the tiles-defs file specifying only the TITLE and BODY ..a la definition name=page.profile.edit extends=base.definition put name=title value=Edit Profile Page / put name=body value=/jsp/profileEditBody.jsp / /definition Bue heres the question... how do I call this thing from an Action Class?!?!?!

Re: Caching Appliction Level Data?
Hi again
a related question. if I load up the data I need from within a plug in
and store it in the application scope, is this an acceptable
sepatation of view and Model as long as I am doing so from a
service?
Remember, this app architecture I'm using has a service factory
(which was set up from within a plug in), and the way all the data
access is done is from these services.
Does that make sense? Essentially, I'll add a section to the init()
after this service factory is set up that uses the service factory to
instantiate a service whose purpose it is to pass back Application
Level data (I use the example of state codes, common to all users)
which I will then store in the application scope.
Am I making sense?
My goal is to keep this as simple as possible by introducing as little
complexity as possible
Dave J
P.S. I mean no disrespect to people who have suggested other ways of
doing this, I'm simply proposing what seems like a simple solution,
and wondering is it seems drastically wrong, or if it's reasonable.
thanks to everyone for the input!

I see what you mean. I was assuming I'd just store the data in a
hashtable or something in the Application Context
That's what I think Wendy suggested, and it's probably a better idea than
what I do frankly :)
I have stupid question...where is your AppConfig actually getting
stored? I'd think you'd need to do the above at some point and do a
No question is stupid :)
getServletContext().setAttribute( AppConfig, myAppInfo);
oh boy what am I missing.. or was that implied.. OR did I miss your
hwhole point? I really hope it's not the last one ;)
Your forgetting some basic Java is all (and everyone does it from time to
time, regardless of what anyone might claim :)
A member of a class that is static is always present in the CLASS,
independent of any instance of that class. For instance:
public class myClass {
public static int PI = 3.14159;
}
Now, if you have another class that wants to use PI, you just do:
public class test {
public void showPI() {
System.out.println(myClass.PI);
}
}
No instance of myClass is created, yet you can access the PI member of it
through the instance of the CLASS... That's sometimes confusing to
people... The way I learned to think of it is that the JVM (the class
loader specifically) in a sense does automatically creates an instance of
the myClass class, but an instance that ONLY contains the static members.
That's not actually what happens AFAIK, but IN EFFECT it is.
As long as the two classes are loader by the same class loader, your good
to go.
For this app it's safe to assume we'll always be using struts (btw)
Then a plugin is safe. But, as others have said, it's just about as easy
to do it other ways, so you may as well have one less Struts tie-in. And
as Vic I think said, DAOs are the best-practice (one I haven't had cause
to use yet myself, but I in *no way* disagree with his point).

Using a plugin only tells you WHERE your going to read the information

want to ask. Plugins are pretty standard practice when dealing with
Struts, but if you have a concern that you might not be using Struts at
some point, you might want to do something else.
In any case, where you put the data is the question. I'd still put my
vote down for a static storage class. I do that, read the data in a
plugin, stick it in the storage class, and I'm done. The storage class
is
pretty much nothing more than this:
import java.util.HashMap;
public class AppConfig {
private static HasMap config = new HashMap();
public static void setConfig(HashMap config) {
this.config = config;
}
public static HashMap getConfig() {
return config;
}
}
I start my plugin by doing:
HashMap config = AppConfig.getConfig();
...then read in whatever data I need, shove it in config, and final do:
AppConfig.setConfig(config);
Again, so long as this data isn't going to change, and it's not a huge
amount of data, that's all there is to it. I don't know if this would
be
considered best practice', but it's certainly common practive AFAIK

If you're on a Servlet 2.3 or later container (which is when ServletContextListener was introduced), you should use it instead of plugins: * There are also other listeners that you should explore which are available in this version -- did you know, for example, that you can be notified whenever anyone else in your app adds, removes, or replaces an application or session scope attribute? (In Servlet 2.4 you can do this for request scope too.) * The way a Struts plugin is implemented is to have the init() and destroy() methods called from the corresponding methods on ActionServlet.
