[struts-faces] tag with module

[Ng Chong Hin NCS]

Hi!
 
  Currently, I am in the midst of converting a working Struts application
(JSP/Tiles/Modules) to one that uses JSF, using the struts-faces integration
library.
 
  Having problems retrieving the messages from the
"message-module1.properties" resource (defined in the
struts-config-module1.xml) ...
 
  When attempting to use the message key like , an
exception is reported:

It was based on log files that we found this error. This has happened for
couple of screens. It will work through out well, pass all the variables
properly and all of a sudden it will not pass one such varaible whereas all
other variables will be passed in the same screen. This is killing me. We
use Internet explorer(5.5 or above) and Netscape(4.7 or above). I have never
seen any user reporting the errors while using Netscape so I'am assuming
that it is a browser error. The difficult part is we are not able to
replicate the same scenario as this occurs once in a blue moon. Moreover
this has happened when there are few or more concurrent users. Wanted to
know if any of you have got the similar error. If there is a possible
solution please let me know.

Thanks

Hi, 
I try to use sitemesh instead of tiles; in my “decorator” template page I need 
to include a struts action.
I try to do this:

RE: Deprecated Method

In your action, instead of:

servlet.getResources(); // Deprecated

Use

this.getResources(request); // Not Deprecated

RE: implementation of permission subsystem

[Joe Hertz]

You tried the Declarative Security model built into Tomcat? You can use
that to talk to the database by defining a "JDBCRealm".

Or even better (since that doesn't give you a login form you can use the
way you might expect to), take a look at SecurityFilter, which is what I
use.

Re: implementation of permission subsystem

[Ding Lei]

One more thing, the system stores all user & group information in database
So storing role information in a tomcat/struts configuration isn't really
possible.

implementation of permission subsystem

[Ding Lei]

Hello folks,
I am working on a DVB(Digital video broadcasting) content management
webapp, which is based on the struts framework. It mainly includes application,
service,network, user,broadcasting management & etc. The system is originally
designed almost without considering security issues, i.e almost all operations
are done without permission check.
   Later on, I spent quite a few days attempting to implement a General permission
control arch. with Dynamic Proxy, which checks a method's permission at runtime by 
it's name.
But soonly found out that this sytem's methods' naming are really a mess. For ex,
some methods are called "del" which actually does the "remove" operation, & vice versa.
Even worse, same type of methods takes very different type of arguments  
a DVBUserManager.removeUser takes a DVBUser object as argument, and a 
DVBNetworkManager takes
a DVBNetwork object as argument. 
  So .. I found then I was endlessly adding bunches of "if" to handle different 
specific
methods in the Dynamic Proxy class.
  My question is, is there any good permission control framework provided 
directly/indirectly
for Struts/Tomcat based applications  ? 
  If not, would you please suggest some others?

  Thank you.

Re: Controller for web services

I probably wouldn't bother replying to this, since a lot of it is supplanted 
by what I did for the later public WS project.  I would just ignore what I 
posted here, it's kind of old news at tis point :)

Have you looked through the documentation on my quick project site?  The 
Technical Details there is probably what your most interested in.

  Written this way it seems more interesting: one could use the same struts

  You're right. One still needs to make a custom processForm on

  Check the chapter 15 sample from the book Java Development with Ant. In a
day or two you get the main picture (it covers web services development with
ant and .net integration).

  Just handling strings is a little limited but what if... Instead of having
the form defined and populated as a regular bean, why not make the
marshaling of the xml document inside of the soap envelope?
  You do have the syntax that should be sent on the envelope. You just need
the right bean to marshall to. (It may not be marshal but unmarshal... I get
them both confused, all the time).

Off the top of my head I would look into whether or not PeopleSoft

Re: HTTP header for dynamic pdf and IE6

I'm doing this as well, and three things come to mind...
(1) For IE, you must set the response size or it'll choke.  Looks like

(2) Try adding response.setContentType("application/pdf"); to your 
code.  That's the only extra thing I'm doing in my code. 
I am setting the content type as stated above. The best way to see that 
is to check my header that I included
in the email message. As a side note, I am not setting the charset, it 
seems that gets set automagically when I
call response.setContentType("application/pdf");

(3) Acrobat integration with IE is known to be buggy, and that's being 
polite!  In Acrobat itself, there is an option to specify whether the 
PDF is opened integrated in the browser or in a separate window.  The 
former is many times problematic.  Try changing that option and see if 
your problem goes away.  In Acorbat 6.0, it's under the Edit menu, 
Preferences, the Internet "tab", and it's the Display PDF In Browser 
option.  Uncheck it, close Acrobat (make sure it's really closed, I 
find the Acrobat process keeps running most of the time, very 
annoying) and give it a try. 
Since I am creating a public website, I really don't want to force the 
user to reconfigure their machine. As I stated in my original
message, Yahoo mail seems to handle this OK. They are doing some bizarre 
things though. Most interesting is adding filename="foo.bar"
to the content type. I tried playing with that stuff, but as I noted 
earlier, I am missing something.


Hope that helps!

Subject: HTTP header for dynamic pdf and IE6
Date: Fri, 04 Jun 2004 08:37:45 -0400
Sorry if this is inappropriate for this list,
but I really don't know where else to turn. I
figured someone on this list may have solved it.
I have a java web application that allows
an end-user in their browser to download
a "file", which happens to be bytes stored
in a database.
In experimenting with how to do this, I have
this snippet of code in my Action:
   AttachmentListItem attachment =
EmailSQL.getAttachmentListItem(connection, 3, 1);
   response.setContentType(attachment.getContentType());
   byte[] data =
EmailSQL.getAttachmentBytes(connection, 3, 1);
   response.setContentLength(data.length);
   response.setHeader("Content-Disposition",
"attachment; filename=\"" + attachment.getFileName() + 
"\"");
   ServletOutputStream out = response.getOutputStream();
   out.write(data);
   out.flush();
   out.close();

To test this out, I hit the link in my IE browser which brings up
a dialog box allowing me to "Open" or "Save" the file. If I save
the file, it does the right thing. If I press the open button, Acrobat
Reader opens up and then errors out with an alert box:
"There was an error opening the document. The file does not exist."
I have a yahoo email account that I tried a test on. I sent an email
message with the same pdf file attached to that account. I wanted to
see if yahoo figured out how to make this work. They did! (but I can't
figure out how to replicate)
Their header looks like this:
Date: Thu, 03 Jun 2004 15:37:58 GMT
P3P: policyref="http://p3p.yahoo.com/w3c/p3p.xml";, CP="CAO DSP COR CUR
ADM DEV TAI PSA PSD IVAi IVDi CONi TELo OTPi OUR DELi SAMi OTRi UNRi
PUBi IND PHY ONL UNI PUR FIN COM NAV INT DEM CNT STA POL HEA PRE GOV"
Content-Disposition: attachment; filename=reference.pdf
Connection: close
Transfer-Encoding: chunked
Content-Type: application/pdf; filename="foo.bar"
.s4g--&v=1
There is also some other stuff I am seeing just after the header: 
.s4g-&v=1
which looks something like a query string, but I'm not sure.

My header looks like this:
HTTP/1.1 200 OK
Date: Thu, 03 Jun 2004 15:35:15 GMT
Server: Apache/2.0.40 (Red Hat Linux) mod_perl/1.99_07-dev Perl/v5.8.0

Content-Length: 214982
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive

Does anyone know how to work around this problem? I suppose
there are actually 2 parts to this:
1) What is the magic in the HTTP header that allows this to work?
2) How can one create such a header in java?
Thanks.

RE: [OT] thick client functionality in the browser

[Frank Zammetti]

Cheers for the span tip. It will reduce some of my needs for double
requests.  However sometimes the iframe saves requesting more than 
necessary
in the response - eg when searching data, only replace the inside of the
iframe.
You know, I'm sitting here wondering why I never just refreshed the 
iFrames?!?  Kind of DUH moment for me!

On something else relevant... My applications are also frame-based, which I 
know many people hate, but that's something else that will allow you create 
richer interfaces in my opinion.  First, you can have portions of the screen 
that never change, that's what I've done a lot of.  All three applications 
that I referred to have similar appearance, that is, they start by opening a 
new window with no chrome (i.e., just an empty frame, no browser buttons or 
menus or anything), and in this I load a frameset that usually consists of a 
menubar up top, a bar on the left and a status bar on the bottom, plus a 
main frame in the middle of it all.  Only the middle frame ever changes, all 
the others are never loaded after the first time.  I change their content 
via script functions in an API.

The API is the other important thing... I create a hidden frame (just set 
it's size to 0 in the frameset) and in this frame I load a large collection 
of script functions that are used throughout the application.  The benefit 
here is that all that stuff doesn't have to be retrieved with each request.  
So, these functions form an API for the application, maybe I have a 
setStatusMessgage() function, and a loadSidebar() function, things like 
that.

What I do is when I call on the server to generate a page for the main 
frame, I display a "Please Wait" layer that is included in all the main 
pages the server renders.  I also hide the content in the other frames.  So, 
I get a nice waiting screen while the server is loading (usually with some 
kind of animation, a clock spinning for instance).  When the page is 
returned, it by default has the same Please Wait layer showing and it's main 
content hidden, the appearance is that the Please Wait screen is showing 
until the page is completely loaded.  Very nice.  Then I hide the Please 
wait layer and show the main content, but not before the appropriate 
functions in the API are called to set up the other frames (i.e., status 
message, links on the sidebar, etc).

The other benefit to this hidden API frame is that you can store persistent 
data in there in JavaScript variables and use them on many different pages.  
This is how I do the client-side sorting stuff... I load an array in that 
frame, then render the mani frame's contents off that array.  When the user 
wants to sort by a different column, just call the sort() function and 
re-render the contents (done in one call actually).

These are just some of the tricks I've developed over the years.  If anyone 
wants to discuss this further, I'm all for it, but I'm not sure how 
appropriate it is to the Struts list.  If people are interested though, and 
no one objects, it might make a nice thread, something like "Rich GUI 
tricks" or something.

Deprecated Method

[Jason L. West, Sr.]

I am finishing up a series of WROX books that are focused on the
JSP/J2EE development with the last book of the series focusing on
developing Struts Applications.  Unfortunately the series was published
in early 2002 with focus on the Struts version 1.0.

One of the methods the book talks about has been deprecated with the
release of Struts version 1.1.  What I would like to know is new or
better method of doing the following:

public void reset(ActionMapping mapping, HttpServletRequest request) {
 ActionServlet servlet =  this.getServlet();
 MessageResources messageResources = servlet.getResources(); //
Deprecated

 storyTitle = 
messageResources.getMessage("javaedge.poststory.title.instructions");
 storyIntro =
messageResources.getMessage("javaedge.poststory.intro.instructions");
 storyBody  =
messageResources.getMessage("javaedge.poststory.body.instructions");
}

Any insight would be helpful.

Thanks

Use the styleID attribute of the  tag. That resolves into the
"id" attribute of the HTML  tag. Then you can access that form from
Javascript using the "getElementById(...) function, which works on IE and
Mozilla based browsers.

RE: [OT] thick client functionality in the browser

[Daniel Perry]

I can see where you're going with the mixing of business logic and views.

I will admit that in parts i have done this.  A quick javascript check gives
a much quicker response that submit/redisplay form.  Especially when you get
some of the massive pages in our system.  One solution i had was to do both.
The javascript deals with validation, for the user, but the business logic
also validates data using actionforms, and only proceeds if it passes.

Cheers for the span tip. It will reduce some of my needs for double
requests.  However sometimes the iframe saves requesting more than necessary
in the response - eg when searching data, only replace the inside of the
iframe.

Daniel.

Re: [OT] thick client functionality in the browser

[Frank Zammetti]

Geez, I hope your not talking about an app I did part of a couple of years 
ago! :)  Sounds very familiar... We had some Cobol jobs on a mainframe who's 
output we ran through something from IBM called Web Templates... It's meant 
to generate HTML, but instead we generated XML from it, then sent that XML 
to another server where it was processed via XSLT to generate the final 
HTML.  It was also rather script-heavy (eh, it was cool at the time, and I 
wasn't lead on the project, so I only accept partial blame! :) )

I agree with Frank that -- it is amazing what you can do with JavaScript 
and IE-specific stuff.  A few jobs ago I had to inherit an heavy JavaScript 
app where the page was generated with XSLT.  I converted to use Struts but 
I had to preserve the JavaScript.  It is difficult to keep the MVC 
architecture -- one thing you can do is use Struts/JSTL tags to generate 
the JavaScript -- such as arrays, etc. The app I inherited was doing this 
using XSLT so it wasn't too difficult to migrate to Struts.  I didn't have 
access to JSTL at the time -- my guess it would have been even easier using 
JSTL (heck, I could have used the XML tags).

RE: [OT] thick client functionality in the browser

[Frank Zammetti]

I agree with this.  Our app is IE only, and it's amazing what you can do.
IFRAME's make great scrollable tables.  The use of
document.getElementById("xxx").style.display="none" (or "") for
hiding/unhiding stuff is very extensive.
You know what I discovered about a month ago?  Instead of using iFrames, you 
can get the same functionality with a  with style="overflow:scroll;".  
In every way I can determine, it looks and works the same, but now instead 
of either having the server serve a second page to populate the iFrame or 
having script generate the HTML for it when the parent loads (which I did a 
lot of previously), you can how use regular JSP code (taglibs hopefully!) to 
generate the HTML inside the .  It speeds things up so much!

I disagree with the comment about layers tho.  Our jsps are still only
displaying stuff.  They arnt doing anything that the business layer should
atall.
Javascript/dhtml is amazing if you persist with what you want.  I came
accross a webmail system the other day that i couldnt believe wasnt using
anything else for gui!
I agree, you certainly CAN maintain good architecture.  That's where my 
story about my past three apps came in, how the most recent was is 
infinitely better in terms of separation of layers.

The point I was trying to make, probably not very well, is that it's EASIER 
to screw up this way.  You can easily become tempted to put pieces of 
business logic in the view because you realize "gee, if I do x, y and z via 
scripting I don't have to have the server do it!".  Things like validations 
for example... just checking if a field is filled in is of course fine to do 
with script, but if you start doing "if field X is greater than the maximum

problems.  It's tempting because you CAN do it in script and the result is a

RE: Strus Web Service Enablement

[Frank Zammetti]

Point here, if I understood correctly, is that frank is implementing
The serverside part. So if you or I or anyone else would use his
package,
It will be for enabling an existing struts application to be called
As webservice.
That's spot-on.  I'd say if you were developing new services, or really 
doing more advanced Web Service-type things, this package probably isn't the 
right fit there.  But if your in a situation like I was a short time ago, 
where you have a big, exsiting Struts application, and someone wanted to 
access portions of it, this I think can be a quick and easy way to do that.

Specifically in my case I had another web application written by another 
group that wanted to access a list of items from my application.  Since my 
application is fairly well-written, I had beans that generated the list 
independant of the Actions, and I could have gone through the exercise of 
exposing those as as service.  But, I started thinking, wait, I have this 
whole server infrastructure, including in my case externalized security, and 
wouldn't it be nice if I could plug into that without touching any existing 
code?  Fortunately, I had done basically what this project is about three 
years ago in a home-grown framework, so it was trivial to port it to Struts, 
and it worked like a charm.

It's cases like this where I think this package could find some use, not in 
delivering oodles of new Web Services like many companies are doing.  There 
are far better options for that.

AFAIK, ultimately in an XML message everything will be reduced to a
String.
If u need for some reason to map it to a specific type, have a look at
The org.commons.beanutils.ConvertingWrapDynaBean class and see if it can
help
Yes, that's absolutely correct.  However, SOAP, as far as I know it, allows 
for more complex types to be encoded.  I assume it does some sort of 
serialization on it and stuffs the resultant bytestream into a CDATA 
element, or something of that nature.  On the server side, that stuff gets 
reconstituted and you wind up having your objects to work with, like 
BigDecimals, HashMaps or whatever else SOAP allows for.  My code won't 
handle such things at this point, and fundamentally I'm not sure it ever 
could, or even that it should.  When you consider that you are submitting 
your SOAP request to something that was meant to service HTML form 
submissions, which only deal in Strings, it makes sense that this would be a 
limitation of my approach, and it further makes sense that it's really not a 
limitation per se.

Dunno what the client would to though..

dynamically on the client side can any body please tell me how to do it.
We cant use arrays of objects of line items beacus its size has to be

RE: [OT] thick client functionality in the browser

[Frank Zammetti]

I've personally made something of a career out of doing what your talking 
about.  The applications I've built at work are known to have very 
Windows-like look, feel and functionality, much more so than most other 
web-based applications.

To pull it off, two things are true... first, it is IE only.  This is 
because of the secone: they are very heavily JavaScript, Dynamic HTML and 
CSS-based GUIs.

It *IS* possibly to do this type of thing in a cross-browser fashion, but I 
think it's fair to say it is considerably harder, and certainly more 
time-consuming.  Standardizing on IE for us was easy because it's already 
the corporate standard, and is for 99% of our clients (the other 1% we 
simply tell they either use IE for at least our apps our they don't use the 
apps... not too nice in my mind, but it's been accepted thus far).

Whether you try to do it cross-browser or not, most of your time will be 
spent doing scripting.  You can do some truly amazing things that will make 
you forget your looking at a web-based app, for the most part.  You can also 
in many cases get much better performance because the more you do on the 
client (assuming it's not processor-intensive since your talking about an 
interpreted scripting language), the better PERCIEVED performance the app 
can have in many cases.  A good example is one application where I sort a 
returned list of search results on the browser as a result of a click of a 
column header in an iFrame, which makes it work just like a grid in Windows. 
 People love that, and so do the server admins since I'm not having the 
server sort search results.

There are absolutely trade-offs you have to be aware of along the way, but 
this is the way I'm pulling it off, and the way I think most people are, 
without resorting to plug-ins, Flash, Applets, ActiveX and all that sort of 
stuff.  Pure HTML and JavaScript (well, as pure as you can get when it's 
IE-only!), and you get what you want without most of the headaches.

The other big thing to consider is that you VERY quickly break "proper" 
application architecture, i.e., separation of layers.  It's almost 
unavoidable when your doing something like this unless you are exceptionally 
careful.  I've done three huge applications along these lines over the past 
four years, the first two were pretty poor in terms of separation, the third 
is actually very good, but I learned a lot of lessons from the first two, 
and even still there are things done that probably shouldn't be.  If this 
isn't your biggest concern (as it's not here since fulfilling client 
requests always trumps proper application development, bad as that may be in 
theory!), then it's fine.  If your an absolute architecture purist (i.e., if 
your a Ph.D, which we have way too many of these days!), then you'll 
probably fight such an approach tooth and nail, and continue to either (a) 
have trouble with how your applications work or (b) develop less powerful 
interfaces because your more concerned with the structure of an application 
than what it looks like and feels like and works like for an end user.

Now that I've opened a theological nightmare here... ;)

What are people out there using to get thick client functionality in the

CORRECTION: Alias names that can be used in javascript to refere nce ......................

Sorry, minor correction in example needed:

The java script should be

dosomething() {
  alert(document.somethingFormConfigOptionA.command.value);
  alert(document.somethingFormConfigOptionB.command.value);

Subject: Alias names that can be used in javascript to reference  when using multiple forms that could point to the same action?

I am in the process of removing all our Struts 1.0 deprecated code in
anticipation of moving to Struts 1.2(when its release).  I was looking at
the  tag and how they removed the "name", "type", "scope"
attributes of the  tag stating that the action mapping will
determine these values.
 
My question is, does anything exist or will exist to refer to a form in
javascript without having to dive into a positional array when having
multiple html:form's tags pointing to the same action?(which maybe a bad
approach to begin with but at this point I am trying to avoid significant
changes to these jsps if possible).
 
Each  had a "name"(I consider it like an alias pre Struts 1.2)
which was being referenced in javascript.  When I removed the "name"
attribute, I think the javascript broke because it could not resolve
"somethingFormConfig1.command.value" since the alias no longer exists.
 
Code tidbit below:

Example that worked pre-Struts 1.2 and now broken:
 
dosomething() {

Struts 1.2 change I put in to make it work but does not seem as

}
 


 
 


 
 

 
NOTE: Assume that the name is "SomethingFormConfig" in the struts-config.

[OT] thick client functionality in the browser

[Wennberg, Mathias]

We're currently running a swing java webstart app but issues with clients jvm
versions and permissions to install/update programs on their workstations are
making us look into alternatives.
What are people out there using to get thick client functionality in the
browser? Ultimately it would work without any plug-ins and on all browsers,
but it's not necessary as long as it works on IE and doesn't use activeX.

I'm also looking for comments and feedback on thinlets and canoo.

RE: Strus Web Service Enablement

[Marco Mistroni]

Hi,

>   How could one use your RequestProcessor if I am using Axis and

Point here, if I understood correctly, is that frank is implementing
The serverside part. So if you or I or anyone else would use his
package,
It will be for enabling an existing struts application to be called
As webservice.

I have used axis long time ago (and not for an advanced example
either..), but  wouldn't it be enough if you construct a SOAP  message
and send it
To the struts app URL?
Will u have any drawback in doing that, if you abstract the way you call
The webservice?


Again, I m no expert with axis, but I thought there was an API that you
Can simply construct an XML message and post it to the webservice URL
(JAXM?)

AFAIK, ultimately in an XML message everything will be reduced to a
String.
If u need for some reason to map it to a specific type, have a look at
The org.commons.beanutils.ConvertingWrapDynaBean class and see if it can
help


Dunno what the client would to though..

Re: Servlet filter

[Nic Holbrook]

I actually extended the Action class with a SecureAction class and 
created a Secure Action Mapping.  All actions that need to be secured 
extend this class.

In the struts config I have  for each action.  This way I validate at the role level for 
each action.  This works great since we build menus based on roles 
assigned to users.

RE: Semi-OT: Organizing WEB-INF/lib dir...

[Satish Kataria]

Instead of you putting all the jar files in the WEB-INF/lib folder
I would suggest that create a directory structure for libraries aoutside
WEB-INF
Advantages  of this is this approach is cleaner and easily mantainable
as 
You can add any new libraries with minimum of effort

e.g the directory structure may look like

Application
libraries
struts
hibernate
Web-inf
lib
classes

And then use ant to include the jars in the classpath. All the web
containers garantee that if you 
put the path of all the libraries using the manifest.mf (which is
created when you create ur
Application's WAR file) then the web container will include them in ur
application's classpath

A sample ant target for including the path of libraries in manifest.mf
is given below






Where ${project.manifest.classpath}  contains the path of all the
libraries. This has to be relative to web application root and not
absolute path

myweb.war  --  the application's war file 
${jar.dir} -- the directory from which to jar the files 

Please revert to me in case you require any other details


Thanks,
Satish Kataria

Quick question for the people more versed in web apps than me, can you 
organized your libs in your WEB-INF/lib dir into separate sub dirs? I 
ask because my project is using Struts and Hibernate right now, and 
there is a such a mish-mash of JARs forming in my WEB-INF/lib dir, that 
its hard for me to upgrade the right jars when a new release comes out. 
I'd like to have something like:

WEB-INF/lib/struts
WEB-INF/lib/hibernate

or something to that extent. Can I do this?

RE: Strus Web Service Enablement

[Frank Zammetti]

  For what I understood you are customizing the RequestProcessor to handle
SOAP message requests, right? I dont see Axis and any way of retrieving
the WSDL to make a direct call...
That is correct.  Any by "handling SOAP message requests", it really means 
"look for the SOAPAction header, if it's there, parse the message and create 
a query string from it, then forward the request back to itself in essence, 
with the query string attached".  It's a very rudimentary facility to be 
sure.

  If so, maybe instead of customizing the request processor, wouldn't it
be best to have a "SOAPform" to process the envelope and then populate
the bean? You could define the form-bean as your SOAPForm handler and a
regular action-mapping.
Hmm... If I understand your suggestion correctly, that would require a new 
class for any Action you want to expose, correct?  That's something I wanted 
to avoid.  It's good in the sense that no code has to change (config files 
don't count in my mind, so that's OK to do), and while adding a whole new 
class isn't as bad in my mind, it's still something I'd prefer to avoid if 
possible.

  With the help of Tiles one could define a template definition to return
the response in the appropriate format.
  Template:
  - soap header
  - soap body
  - soap footer
I haven't looked a Tiles at all yet (I'm actually fairly new to Struts 
still), so I can't really make any intelligent comment on this (except, I 
hope, for the comment that I can't make an intelligent comment on it! :) )

  How could one use your RequestProcessor if I am using Axis and
publishing web services through WSDD or JWS files?
I can't answer that either because while I know a little about Axis (a very 
little), I don't know anything about WSDD or JWS.

  I am new to web services but I found very usefull wsdl2java and have my
clients process their requests in a somewhat transparent way through the
use of SoapBindingStubs.
  It seems that with your approach I can't call a web service with these
stubs but, instead, need to implement some
SOAPMessageBuilder+Marshalling/Unmarshalling of JavaBeans to send SOAP
messages, something that with JWS files, for example, is completely
transparent.
I *believe* these stubs will work, indeed they SHOULD.  One thing I'm going 
to try and do today is write a WSDL file for my sample service and see if 
the client that JDeveloper can generate from it works.  In theory it should, 
if it doesn't then obviously I've done something very wrong.  One of the 
limitations of my code is that only Strings can currently be passed as 
parameters to a service, and only Strings can be returned, so certainly much 
of the full power of Web Services cannot be utilizied (and I'm not sure I 
see any way to change that based on what I've done), so it's possibly always 
going to be of limited utility.  I don't expect that this is going to be 
useful for every Web Service situation, indeed it may only be useful in some 
limited subset.

In any case, you've given me some things to go Google now :)

Re: Transition after registering new user

[Bill Siggelkow]

quickrobert:
Just taking some guesses here ...
Does the user pass authentication when the login after registration?  If 
not, then it sounds like that JBoss is not rereading the security info 
from the database.  If so, then you may need to "fake" the login by 
programmatically going through j_security_check on registration.

Probably the JBoss forums are a better source for this kind of question...
fastbob wrote:
Greetings,
I have an application using Struts 1.1 and JBoss 3.2.3. Authentication is
Forms-based using JAAS. The username and password are pulled from the
database through j_security_check and several authorization levels are

I'm now trying to add a new user registration page. If the registration
succeeds, the user should be logged in automatically and taken to a welcome
page. From the welcome page they should be able the access the application.
The registration info is added to the database and the user is logged in via
javax.security.auth.loginjavax.security.auth.login. Then my registration
forwards to the welcome page. Unfortunately, when the welcome page is
displayed, the user does not appear to be logged in. Clicking on any link
for the application takes them to the login page.
What am I missing?

No, it does not.  UltraEdit is a top-notch text editor, many people 
(including me) think it's the best, but it doesn't have too much in the way 
of "IDE-like" functionality.  The only things I can think of actually is a 
function list and syntax coloring for various languages.  Oh yeah, and 
auto-bracketing of blocks I think.

Your characterization of this discussion is spot on by the way :)  It's kind 
of like that discussion of the best programming language.  Pointless 
ultimately because a good coder can be successul in most any language

RE: HTTP header for dynamic pdf and IE6

[Frank Zammetti]

I'm doing this as well, and three things come to mind...
(1) For IE, you must set the response size or it'll choke.  Looks like your 
doing that already.
(2) Try adding response.setContentType("application/pdf"); to your code.  
That's the only extra thing I'm doing in my code.
(3) Acrobat integration with IE is known to be buggy, and that's being 
polite!  In Acrobat itself, there is an option to specify whether the PDF is 
opened integrated in the browser or in a separate window.  The former is 
many times problematic.  Try changing that option and see if your problem 
goes away.  In Acorbat 6.0, it's under the Edit menu, Preferences, the 
Internet "tab", and it's the Display PDF In Browser option.  Uncheck it, 
close Acrobat (make sure it's really closed, I find the Acrobat process 
keeps running most of the time, very annoying) and give it a try.

Hope that helps!

Subject: HTTP header for dynamic pdf and IE6
Date: Fri, 04 Jun 2004 08:37:45 -0400
Sorry if this is inappropriate for this list,
but I really don't know where else to turn. I
figured someone on this list may have solved it.
I have a java web application that allows
an end-user in their browser to download
a "file", which happens to be bytes stored
in a database.
In experimenting with how to do this, I have
this snippet of code in my Action:
   AttachmentListItem attachment =
EmailSQL.getAttachmentListItem(connection, 3, 1);
   response.setContentType(attachment.getContentType());
   byte[] data =
EmailSQL.getAttachmentBytes(connection, 3, 1);
   response.setContentLength(data.length);
   response.setHeader("Content-Disposition",
"attachment; filename=\"" + attachment.getFileName() + "\"");
   ServletOutputStream out = response.getOutputStream();
   out.write(data);
   out.flush();
   out.close();
To test this out, I hit the link in my IE browser which brings up
a dialog box allowing me to "Open" or "Save" the file. If I save
the file, it does the right thing. If I press the open button, Acrobat
Reader opens up and then errors out with an alert box:
"There was an error opening the document. The file does not exist."
I have a yahoo email account that I tried a test on. I sent an email
message with the same pdf file attached to that account. I wanted to
see if yahoo figured out how to make this work. They did! (but I can't
figure out how to replicate)
Their header looks like this:
Date: Thu, 03 Jun 2004 15:37:58 GMT
P3P: policyref="http://p3p.yahoo.com/w3c/p3p.xml";, CP="CAO DSP COR CUR
ADM DEV TAI PSA PSD IVAi IVDi CONi TELo OTPi OUR DELi SAMi OTRi UNRi
PUBi IND PHY ONL UNI PUR FIN COM NAV INT DEM CNT STA POL HEA PRE GOV"
Content-Disposition: attachment; filename=reference.pdf
Connection: close
Transfer-Encoding: chunked
Content-Type: application/pdf; filename="foo.bar"
.s4g--&v=1
There is also some other stuff I am seeing just after the header: .s4g-&v=1
which looks something like a query string, but I'm not sure.
My header looks like this:
HTTP/1.1 200 OK
Date: Thu, 03 Jun 2004 15:35:15 GMT
Server: Apache/2.0.40 (Red Hat Linux) mod_perl/1.99_07-dev Perl/v5.8.0
mod_jk/1.2.5 PHP/4.2.2 mod_python/3.0.1 Python/2.2.2 mod_ssl/2.0.40
OpenSSL/0.9.7a
Set-Cookie: JSESSIONID=DD3D0938B780EEBEBDC1B558CCBAD095; Path=/
Pragma: No-cache
Cache-Control: no-cache
Expires: Thu, 01 Jan 1970 00:00:00 GMT
Content-Disposition: attachment; filename="reference.pdf"
Content-Length: 214982
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Content-Type: application/pdf;charset=UTF-8
Does anyone know how to work around this problem? I suppose
there are actually 2 parts to this:
1) What is the magic in the HTTP header that allows this to work?
2) How can one create such a header in java?
Thanks.

Re: Reload Ressources on the fly

[James Mitchell]

I don't think that's what Mr. "Newsletter" meant.

You cannot reload message resources without modifying Struts and building
your own custom version.  This is due to MessageResources caching the
fomatted strings.  This will happen with a custom MessageResources
implementation as well.  The only way around it would be to clear the cache
with each call, which I don't recommend for anything outside of development.

Re: and get...()

[Bill Siggelkow]

The reason you "System.out.print(foo.getBar())" printed "null" is 
because that is how the print method is written. If the returned value 
of the method is actually null then the "print" method 
prints the value "null".

Long story short, what you are seeing is result of calling 
"System.out.print" not the result of the returned property value.

Kapisch(sic?)?
Marcelo Epstein wrote:
Hi,
When I use  if the value is null, the tag returns "".
But, when I try, for example, System.out.print(xxx.getProperty()) inside an Action and the property is null. It returns the String "null". 
What is the best practice to avoid printing "null" ? I have to check all values before printing? Is there a better way to do that?

Thanks in advance,
Marcelo

Re: Semi-OT: Organizing WEB-INF/lib dir...

[Frank Zammetti]

If they are dependant on different versions of the same JAR, I suspect 
you'll run into problems no matter what you do.  I guess you have it working 
somehow now, which is a bit surprising to me!  If I understood you 
correctly, you may want to see if the different versions are really 
required, i.e., can you just take the latest JAR and have everything work 
with that?

One suggestion that I can make, a habit I've gotten into, is name your 
JARs liberally, since their names don't matter. I usually name the JARs as 
descriptively as possible (for example, 
"jakarta-taglibs-standard-1.1.0.jar" might be one) and include their 
version, so it's fairly easy to tradk down what's what and at a glance 
tell what versions I'm running. Probably not the ideal answer, but maybe 
it'll clean up the mess just a little.

Quick question for the people more versed in web apps than me, can you 
organized your libs in your WEB-INF/lib dir into separate sub dirs? I ask 
because my project is using Struts and Hibernate right now, and there is 
a such a mish-mash of JARs forming in my WEB-INF/lib dir, that its hard 
for me to upgrade the right jars when a new release comes out. I'd like 
to have something like:

WEB-INF/lib/struts
WEB-INF/lib/hibernate
or something to that extent. Can I do this?

This will give you the clarity of centralising your jars while not

RE: Semi-OT: Organizing WEB-INF/lib dir...

[Frank Zammetti]

Sure, if you added it to the classpath it will work.  But the benefit of 
WEB-INF/lib is that things in there are loaded as needed, you don't have to 
put any of it on the classpath.

Most app servers I believe follow the pattern Tomcat does, which is that 
there is a common folder that you can put JARs in that will be loaded as 
needed and are accessible to all webapps.  Then there is WEB-INF/lib which 
is specific to a given webapp.  In addition to both of those, anything on 
the system classpath is accessible as well.

The point though is that if you put that folder under lib and do NOT added 
it to your classpath, will it still work?  Even if it does, is JDeveloepr 
doing anything for you in the background to make it work?

possibly it would work with another app server, but I tend to doubt it.

One suggestion that I can make, a habit I've gotten into, is name your 
JARs liberally, since their names don't matter. I usually name the 
JARs as descriptively as possible (for example, 
"jakarta-taglibs-standard-1.1.0.jar" might be one) and include their 
version, so it's fairly easy to tradk down what's what and at a glance 
tell what versions I'm running. Probably not the ideal answer, but 
maybe it'll clean up the mess just a little.

Subject: Semi-OT: Organizing WEB-INF/lib dir...
Date: Thu, 03 Jun 2004 20:58:36 -0700
Quick question for the people more versed in web apps than me, can 
you organized your libs in your WEB-INF/lib dir into separate sub 
dirs? I ask because my project is using Struts and Hibernate right 
now, and there is a such a mish-mash of JARs forming in my 
WEB-INF/lib dir, that its hard for me to upgrade the right jars when 
a new release comes out. I'd like to have something like:

WEB-INF/lib/struts
WEB-INF/lib/hibernate
or something to that extent. Can I do this?
TIA

RE: [OT] Good env for struts-based-web-tier and ejb components development

[Frank Zammetti]

Just curious, why do you say UltraEdit isn't good for Java development?
It seems like, and this is the case here at work as well, that there is two 
schools of thought... one group says that IDEs and the like are better 
because of all the added development-specific tools you get (i.e., code 
insight, perspectives, generators, etc.), and the other school says that 
since programming is mostly text editing anyway, then a good text editor is 
all you really need.

I think if your thinking is in the first group to begin with, then 
regardless of how good a text editor anything is your not going to like it.  
Likewise, if your comfortable with just a good text editor, an IDE feels 
like unneeded baggage.

I don't think either way of thinking is better than the other frankly, I 
think people can be just as productive either way if they are comfortable 
with the tools they are using.

Thx for your inputs guys.
Ultraedit is good but not good for java development. I have been using it
for perl.
Jedit is also good but not as good as eclipse.
I have decided to adopt Eclipse+(MyEclipse+XDoclet)+Ant to start my 
project.
Quite powerful combination for me.

thx again.

RE: Struts Web Services Enablement Project : version .02

[Frank Zammetti]

I think the ant thing can be done.  I've only used ant once before, and I 
didn't have to write the script, so it's a good opportunity for me to learn 
about it.

I'm looking at the XDoclet site right now.  I think I may have heard of 
XDoclet before, but I don't at this point know anything about it.  Yet 
another opportunity to learn something new! :)

Hi,
Just one suggestion, but it's not software related
- provide ant-scripts for compiling data..
- eventually if u could add xdoclet-tags to the action class (2 help
lazy users like me who generates struts-config etc via xdoclet..)

Subject: Struts Web Services Enablement Project : version .02
Ok, I just posted version .02 of the newly-named Struts Web Services
Enablement Project (prounced 'SWISS EP' I guess?!?).  Here's the address
again:
http://www.omnytex.com/wst.zip
This version I think is considerably more useful, but I'm still eager to
hear anyone's opinions, comments, suggestions, etc.
Most notably in this version are two changes:
(1) There are no longer ANY required elements to the incoming SOAP
message,
i.e.,  is no longer required.  It still has the flat
format restriction, but it should be cleaner now without even the single
required element.
(2) There is now a Struts plug-in that reads a new
webservices-config.xml
file.  THIS IS OPTIONAL.  You don't have to use the plug-in and you
don't
have to write this config file, but that will limit you to the default
output template dumping all ActionForm members only.  However, I believe
it
will be used more often than not because it allows you to (a) map your
own
XML-rendering JSP's to an Action so that you are no longer limited to
the
default XML template's message format, and (b) allows you to pick and
choose
what ActionForm members are returned by the default template if you
still
want to use it, and even in what order!
There are a number of other more minor changes, but these two I believe
begin to make this project actually worth something (my opinion anyway).
Please, let me know what you think.  Play with the sample webapp, let me
know how I'm doing!

Re: HTTP header for dynamic pdf and IE6

[Henrique VIECILI]

Hi Dean,

I did it once, and i did like this:
(solution for PDF file working on IE and any Acrobat Version)
...
response.setContentType("application/octet-stream"); // Acrobat 4 seems "don´t like" 
'application/pdf'
byte[] data = xxx.getData();
response.setContentLength(data.length);
response.setHeader("Content-Disposition","inline; filename=file.pdf");
  /* extension .pdf makes IE choose Acrobat to open the document
   * content 'inline' avoids popping-up the Open/Save Dialog twice in older IE version 
( 5.0 )
   */
out = response.getOutputStream();
out.write(data);
out.flush();
out.close();

Ok, i´m sure it works with Acrobat4+ and IE5+. I did not tested in Linux and other 
browsers.

Re: Security and Struts (JAAS?)

[Bill Siggelkow]

Ralf,
Forgive me if I misintrepreted what you are asking, but I believe what 
you are wanting to use the Struts "role" attribute on actions for 
application-managed security.

One way is to put a check on every page as was suggested and is done in 
the Struts example.

Another way is to provide a custom RequestProcessor -- this is easier 
than it sounds ...

The "roles" attribute on  is processed via the 
RequestProcessor.processRoles() method. You will want to override this 
method in a Custom Request Processor -- something like:

public class CustomRequestProcessor extends RequestProcessor {
  protected boolean processRoles(HttpServletRequest request,
	 HttpServletResponse response,
	  	 ActionMapping mapping)
	throws IOException, ServletException {

// Is this action protected by role requirements?
String roles[] = mapping.getRoleNames();
if ((roles == null) || (roles.length < 1)) {
  return (true);
}
// Check the current user against the list of required roles
HttpSession session = request.getSession();
User user = (User) session.getAttribute("user");
if (user == null) {
  return false;
}
for (int i = 0; i < roles.length; i++) {
  if (user.hasRole(roles[i])) {
return (true);
  }
}
response.sendError(HttpServletResponse.SC_BAD_REQUEST,
getInternal().getMessage("notAuthorized",mapping.getPath()));
return (false);
  }
}

Hi, i have a portal based on struts.

my problem is the protected area.
i have two roles.

both login via ONE Action

okay, i saved something in session
and did if(session...) in an action,
before a user (a logged in) could

it works okay, but only
if the user enters a URL like

i got validation.errors ...
because the execute() of my action is not called...
so i figured out, that i can use ROLES-attribute
for . nice, but this is jaas, isn't it?
now the (for me) interessting point.
can i add a user (or roles) manually in my 
LogonAction.execute() ?
and when, how?

or how to deal generally?
with two user-roles and ONE-LogonAction.class ?
i also watched tomcat-app, that uses struts/jaas for
authorization, but only with ONE role.
so is there anyone out, how has a tip/solution

RE: Problem with utf-8 encoding with struts

[Piero Colagrosso]

Hi folks,

I've been struggling with exactly the same problem described by Ronald in
his initial post and have a few comments/questions regarding some of the
points discussed in this thread.

First of all, I think it's important for us to be very explicit about
whether we are referring to the encoding of the *request* or of the
*response*:

- As I understand it, Ron's original post is a problem relating to the
encoding used by the server when generating a *response*.

- However, the particular servlet filter being referred to in the follow-up
responses has to do with the encoding used to parse the *request* (please
correct me if I'm wrong).

In order to get a better understanding of what methods/settings apply to the
response and which ones apply to the request, I've found the following
summary to be very useful for me:

1. When processing a servlet *request*, the server uses the following order
of precedence, first to last, to determine the request character encoding: 

- Code-specific settings (the *request* methods setCharacterEncoding()) 
- Container specific settings (i.e., vendor specific)
- The default setting (ISO 8859-1)

2. When processing a servlet *response*, the server uses the following order
of precedence, first to last, to determine the response character encoding: 

- Code-specific settings (the *response* methods setContentType() and
setLocale(), or the JSP page directive equivalent mentioned by Ronald) 
- Container specific settings (i.e., vendor specific)
- The default setting (ISO 8859-1)

It's also interesting to note that in the case of Struts, the contentType
setting on the controller (set in struts-config.xml) only modifies the
*default* encoding, which can be overridden by the other settings which have
higher precedence.

In my case, what I've found is that if I want to make sure that my responses
are *always* encoded correctly (i.e., same as Paul's problem), I've had to
use a filter which actually wraps the response and encodes it in UTF-8 (via
an overriding of setContentType method).  The implementation I'm using is
actually described in detail at the following link:

http://www.javaworld.com/javaworld/jw-05-2004/jw-0524-i18n_p.html

BTW, the above link seems to provide the best and most up-to-date
information regarding all the issues that need to be taken into account in
order to provide end-to-end internationalization of a web application.  A
definite must read!!

Using a filter seems to be the best way to guarantee a consistent response
and request encoding, because then you don't have to worry about all the
other places in the applications (JSPs, taglibs, Tiles config, etc...) which
might incorrectly override and 'break' the required encoding.

Cheers,

   Piero

This is not just a problem with JSTL, it's a "problem" with JSPs in general.
A JSP page will default to the system encoding, and not what you may specify
on the response somewhere up the chain. 

I'm aware of 3 options. 

1) Use a Servlet filter as suggested. This only works on Servlet 2.3 and
higher containers. 

2) add this to the top of your JSPs maybe in an include:
<%@ page contentType = "text/html; charset=UTF-8" %>

3) Use another view technology like Velocity

And that's half the battle. The other half is making sure that you can
accept input as UTF-8. But that's a story for another day.

HTTP header for dynamic pdf and IE6

[Dean A. Hoover]

Sorry if this is inappropriate for this list,
but I really don't know where else to turn. I
figured someone on this list may have solved it.
I have a java web application that allows
an end-user in their browser to download
a "file", which happens to be bytes stored
in a database.
In experimenting with how to do this, I have
this snippet of code in my Action:
   AttachmentListItem attachment =
EmailSQL.getAttachmentListItem(connection, 3, 1);
   response.setContentType(attachment.getContentType());
   byte[] data =
EmailSQL.getAttachmentBytes(connection, 3, 1);
   response.setContentLength(data.length);
   response.setHeader("Content-Disposition",
"attachment; filename=\"" + attachment.getFileName() + "\"");
   ServletOutputStream out = response.getOutputStream();
   out.write(data);
   out.flush();
   out.close();
To test this out, I hit the link in my IE browser which brings up
a dialog box allowing me to "Open" or "Save" the file. If I save
the file, it does the right thing. If I press the open button, Acrobat
Reader opens up and then errors out with an alert box:
"There was an error opening the document. The file does not exist."
I have a yahoo email account that I tried a test on. I sent an email
message with the same pdf file attached to that account. I wanted to
see if yahoo figured out how to make this work. They did! (but I can't
figure out how to replicate)
Their header looks like this:
Date: Thu, 03 Jun 2004 15:37:58 GMT
P3P: policyref="http://p3p.yahoo.com/w3c/p3p.xml";, CP="CAO DSP COR CUR
ADM DEV TAI PSA PSD IVAi IVDi CONi TELo OTPi OUR DELi SAMi OTRi UNRi
PUBi IND PHY ONL UNI PUR FIN COM NAV INT DEM CNT STA POL HEA PRE GOV"
Content-Disposition: attachment; filename=reference.pdf
Connection: close
Transfer-Encoding: chunked
Content-Type: application/pdf; filename="foo.bar"
.s4g--&v=1
There is also some other stuff I am seeing just after the header: .s4g-&v=1
which looks something like a query string, but I'm not sure.
My header looks like this:
HTTP/1.1 200 OK
Date: Thu, 03 Jun 2004 15:35:15 GMT
Server: Apache/2.0.40 (Red Hat Linux) mod_perl/1.99_07-dev Perl/v5.8.0
mod_jk/1.2.5 PHP/4.2.2 mod_python/3.0.1 Python/2.2.2 mod_ssl/2.0.40
OpenSSL/0.9.7a
Set-Cookie: JSESSIONID=DD3D0938B780EEBEBDC1B558CCBAD095; Path=/
Pragma: No-cache
Cache-Control: no-cache
Expires: Thu, 01 Jan 1970 00:00:00 GMT
Content-Disposition: attachment; filename="reference.pdf"
Content-Length: 214982
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Content-Type: application/pdf;charset=UTF-8
Does anyone know how to work around this problem? I suppose
there are actually 2 parts to this:
1) What is the magic in the HTTP header that allows this to work?
2) How can one create such a header in java?
Thanks.

Re: Hidden Variables

[James Mitchell]

The reason I asked that is because I have found that some users seem to
think that they can bookmark pages after submitting a form.  Not sure if
this is what you are seeing, but most of the time, and this is browser
dependent, the saved bookmark will not repost the page, but merely send the
URL, so unless you specify your forms as GET, you may see strange results in
your logs.

Best bet for ruling this out would be to put together some tests.

RE: Strus Web Service Enablement

[salgado.pc]

  For what I understood you are customizing the RequestProcessor to handle
SOAP message requests, right? I dont see Axis and any way of retrieving
the WSDL to make a direct call...

  If so, maybe instead of customizing the request processor, wouldn't it
be best to have a "SOAPform" to process the envelope and then populate
the bean? You could define the form-bean as your SOAPForm handler and a
regular action-mapping.
  With the help of Tiles one could define a template definition to return
the response in the appropriate format.

  Template:
  - soap header
  - soap body
  - soap footer

  How could one use your RequestProcessor if I am using Axis and
publishing web services through WSDD or JWS files?
  I am new to web services but I found very usefull wsdl2java and have my
clients process their requests in a somewhat transparent way through the
use of SoapBindingStubs.
  It seems that with your approach I can't call a web service with these
stubs but, instead, need to implement some
SOAPMessageBuilder+Marshalling/Unmarshalling of JavaBeans to send SOAP
messages, something that with JWS files, for example, is completely
transparent.

Hmm. I guess that rules out the chance of it being caused by multiple

RE: Saving state.

[Miquel Angel]

I'm goin to explain the situation with more details:

I have a grid in JSP1. This grid shows information related to customers.
This JSP1 also have 3 textfields which allow the user to filter the
customers to be shown in the grid (name, address and phone number). This
textfields are defined in the ActionForm.
From JSP1, selecting 1 customer and clicking the button Details, he can go
to a 2nd jsp, JSP2. This JSP2 shows the details of a customer (all the filds
we have in DB. Of course this fields are definied in the ActionForm).
From JSP2, clicking the button Orders, the application goes to the JSP3.
This JSP3 shows all the orders related to the customer of JSP2.
From JSP3, selecting 1 order and clicking the button Details, the
application goes to the JSP4. This JSP shows the details of the order.

Being in JSP4, the user can click the button Cancel, and the application
goes back to JSP3. At that moment I need to know the Id of the Order(*).
Being in JSP3, the user can click again the button Cancel, and the
application goes back to JPS2. At that moment I need to know de Id of the
customer(*).
And finally, being in JSP2, , the user can click again the button Cancel,
and the application goes back to JSP1. And here I need to know what
information entered the user to filter all the customers(*).

(*) At this moments, I need to retrieve information that the user entered
sometime in the past. My question is ¿how show I store that information?
¿Shoul I implement an stack? ¿Is there any standard method to do this? Our
initial idea was to save the actionforms in the session, and retrive them
when we need them.

Thanks in advance.

Hi!

What state are you trying to remember?

If it is the preparation of the grid in JSP1, then u can either save the
attributes as session attributes or the results as a session attribute.

Also, if everything is related to an ID, then u can reconstruct links with
the id in all links on the page.

You need to be a little more specific to get a more specific answer to your
scenario.

HTH anyway!

RE: Security and Struts (JAAS?)

[Václavík Radek]

Why don't you use a tag to check the logon on every page you want a secured
access to? Just like in the struts-example:

at the top of your JSP goes: 
<%@ taglib uri="/WEB-INF/app.tld" prefix="app" %>


and the class that is behind this has to extend TagSupport. See the
struts-example for more details.

RE: How appropriately access message-resources from Form classes??

[Cosyns Xavier]

It's for field validation purposes,

Eg: 
Error.mandatory=Attribute {0} is mandatory.
Key.field.one=name
Key.field.two=description
Etc...

The validator framework does it, but I got forms that needs quite more
complicated and conditionally validations that I can not do with the
validator framework.

RE: How appropriately access message-resources from Form classes??

[Joe Hertz]

Call me nosy here, What sort of values would you want internationalized
this way?

I would think that the parameters should be just that -- parameters.
Essentially you "should" be trying to fill in the blank in some string.
At least that's what the framework envisions...

Ex:

My name is {0}

Or

Me llamo es {0}

Does it matter to your app if {0} is Joe or Jose'? Is it not something
you can handle in the message text itself?

Kind of curious now...

RE: URL regd Servlet filter

[Jose Ramon Diaz]

> can you give an outline of the typeof problem you faced?

 I started one discussion last week, but it?hasn?t been answered :)
It said...

I am trying to wrap the HttpServletResponse to apply gzip compression on
data sent to the client when gzip is supported. I'm using a filter,wrapper
and custom ServletOutputStream based on published code.
It seems to work except when I chain actions. If I call one action which
executes a forward to a JSP, I get the exception attached.

We have the filter applied only to *.do in  from web.xml, so we
thought the filter is applied to the actions, and the JSP.

We know this question has been asked several times, but we have not found a
good solution for us. what could I be doing that would cause the stream to
be closed? Can?t we put a filter to compress if we use forwards from
actions?

Thanks in advance!

Don?t you have problem with filters if the actions forward to JSP?
At least, I have a lot of problem with compression filters, as the container
seems to use another request for the JSP.

RE: Saving state.

[Kunal H. Parikh]

Hi!

What state are you trying to remember?

If it is the preparation of the grid in JSP1, then u can either save the
attributes as session attributes or the results as a session attribute.

Also, if everything is related to an ID, then u can reconstruct links with
the id in all links on the page.

You need to be a little more specific to get a more specific answer to your
scenario.

HTH anyway!

Subject: Saving state.

Hi. I'm developing an application with Struts 1.1, Tomcat 5 and
Eclipse. I 
explain my problem:

This situation is: I have 1 jsp (jsp1) that shows information in a
grid. 
>From this grid I can go to the jsp2, where I can see the details of 1 row
of 
the previous grid. From jsp2 I can go to jsp3, where I can see aditional 
information about the record shown in jsp2. From jsp3 I can go to jsp4 to 
see any other information, and so on. My problem is not going forward, my 
problem is goin back. ¿How can I retrieve the state of each action form? I 
use scope="request". ¿Should I implement an stack to save the differents 
actionform's? Is there any example of stack. ¿Should I implement any other 
system?

I would appreciate your help.

Thanks in advance.

Security and Struts (JAAS?)

[Ralf Bode]

Hi, i have a portal based on struts.
and i have some public action.
(e.g for listing news and so on)
however.
my problem is the protected area.
i have two roles.
->customer
->supplier

both login via ONE Action
(i got their roles via their usernames...)
okay, i saved something in session
and did if(session...) in an action,
before a user (a logged in) could
do some stuff.

it works okay, but only
if the user enters a URL like
host:8080/trashApp/cust/addStuff.do
(for submitting a form)
i got validation.errors ...
because the execute() of my action is not called...

so i figured out, that i can use ROLES-attribute
for . nice, but this is jaas, isn't it?

now the (for me) interessting point.
can i add a user (or roles) manually in my 
LogonAction.execute() ?
and when, how?

or how to deal generally?
with two user-roles and ONE-LogonAction.class ?

i also watched tomcat-app, that uses struts/jaas for
authorization, but only with ONE role.

so is there anyone out, how has a tip/solution
for me?

thanks alot!

Ralf

How appropriately access message-resources from Form classes??

[Cosyns Xavier]

Hi,

I want to do some custom validation inside my ValidatorForm but
encountered some problems in displaying in a 'struts-recommended way' my
error messages.

>From inside a ValidatorForm I can not find a way to access the resource
bundles configured in the struts config file. I need it because I want
to create an actionError with internationalized arguments.

Something like this:
ActionError("my.error.key", getResourceValue("my.first.arg.key"),
getResourceValue("my.second.arg.key"));

But I do not know how to access my properties in a 'struts' way inside
my ValidatorForm.

With Action there are no problems as we have a getResources() method.

Does anyone have some idea about this,

Thanks,

Subject: Struts Web Services Enablement Project : version .02

Ok, I just posted version .02 of the newly-named Struts Web Services 
Enablement Project (prounced 'SWISS EP' I guess?!?).  Here's the address

again:

http://www.omnytex.com/wst.zip

This version I think is considerably more useful, but I'm still eager to

hear anyone's opinions, comments, suggestions, etc.

Most notably in this version are two changes:

(1) There are no longer ANY required elements to the incoming SOAP
message, 
i.e.,  is no longer required.  It still has the flat 
format restriction, but it should be cleaner now without even the single

required element.

(2) There is now a Struts plug-in that reads a new
webservices-config.xml 
file.  THIS IS OPTIONAL.  You don't have to use the plug-in and you
don't 
have to write this config file, but that will limit you to the default 
output template dumping all ActionForm members only.  However, I believe
it 
will be used more often than not because it allows you to (a) map your
own 
XML-rendering JSP's to an Action so that you are no longer limited to
the 
default XML template's message format, and (b) allows you to pick and
choose 
what ActionForm members are returned by the default template if you
still 
want to use it, and even in what order!

There are a number of other more minor changes, but these two I believe 
begin to make this project actually worth something (my opinion anyway).

Please, let me know what you think.  Play with the sample webapp, let me

know how I'm doing!

Frank

Shilpa,
We are doing just that. A filter comes into effect before the control goes
to the servlet. So if you can stop the user at the filter level you are
actually saving some processing. We are checking for the presence of session
in the filter.

Subject Servlet filter







hey all,
Preventing users from accesing action. I am writing a web app to manage
administrators and profiles.
Administrators may access to the web app based on the profiles they have.
The profiles, determine which pages the administrator might access. The
profiles, and authorizations, might change online during work, so I need
to
check authorization to access a page (Action) on each access.If I
understand
correct, then, the actionServlet, first process the form bean, and then
the
action..
But, if the user is not authorized to access a specific page (Action), I
need to forward him to an UnAuthorized error page, before thr formAction
bean is filled.
I would like to use a servlet filter. This filter checks the users rights
and instanciates a HttpServletRequest-Wrapper.But am not sure how - .Can
anyone help.Till then me trying to study the ServletFilter examples here n
there.
Shilpa

Re: How can i avoid the use of & in a drop down box ?

[John Antonakos]

thank you, i understand now...
but unfortunately i cannot use that, cause im using javascript and 
HTML dynamic options (eg select1.options = new Option ('',''); )
using a pre-loaded list of data. Those data have & inside,
so there is nothing i can do on the matter, instead of creating
a javascript function to dynamically replace & with &.

I wanted to avoid this option, but its the only option i have.

Thanks anyway for the tips.. John

Struts Validator & Date Patterns

[Enrique Medina]

Hi,
I would like to know if it's possible to indicate a validation of
type "date" indicating as a dattePatern/datePatternStrict a key from
an application resource message file. I mean, instead of:



datePatternStrictMMdd

to be able to indicate the "MMdd" dynamically (to be found
through a key in a resource bundle).
Thanks in advance,
Enrique Medina.

Re: Sorry : Semi-OT: Organizing WEB-INF/lib dir...

[Mark Lowe]

I think you perhaps what to organise you jars in a central place like
~/Projects/lib/struts-1.1
~/Projects/lib/hibernate-2.1
~/Projects/myapp/src
and such like
and then use ant to copy the dependencies into
~/Projects/myapp/build/WEB-INF/lib
at build time with an ant task.
This will give you the clarity of centralising your jars while not  
comprimising anything with the container spec.

Re: Semi-OT: Organizing WEB-INF/lib dir...



Dont think jsp/servlet specs allows splitting of the lib
 dir.  You may want to take a look at maven.apache.org
 or use the way Maven names it dependencies jar files
 good luck.

RE: [OT] Good env for struts-based-web-tier and ejb components development

[Navjot Singh]

Thx for your inputs guys.

Ultraedit is good but not good for java development. I have been using it
for perl.
Jedit is also good but not as good as eclipse.

I have decided to adopt Eclipse+(MyEclipse+XDoclet)+Ant to start my project.
Quite powerful combination for me.

thx again.
