How to forward from one LookupDispatchAction to another LDA

[Riyad Kalla]

Hello,
I have a situation where my LookupDispatchAction (LDA) has all my 
functionality for a particular entity defined in it (lets say 
"Product"). So that includes adding, removing, listing, editing and 
changing their order (moving them visually up/down in the table they are 
listed in).

So far everything works fine, however I am running into a problem when I 
have my LDA returning a forward BACK to itself. This situation arises 
when someone changes the order of a product (maybe they move it down), 
so what happens is the "Down" button is pressed, execution goes to the 
"moveDown" method in the LDA. At the end of that method, a forward is 
returned that actually points to the same LDA, but is suppose to call 
the "showList" method (different path). This is done because after the 
order of the products is changed, you need to refresh the page with the 
list of products again so the user sees the changed ordering.

However, as you can imagine, I get the following exception after 
returning the forward:

javax.servlet.ServletException: Request[/forward/product/showList] does not contain 
handler parameter named method

org.apache.struts.actions.LookupDispatchAction.execute(LookupDispatchAction.java:199)

org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:484)
org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482)
org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:507)
javax.servlet.http.HttpServlet.service(HttpServlet.java:743)
javax.servlet.http.HttpServlet.service(HttpServlet.java:856)
I've tried (at the end of the 'moveDown' method) to manually set a 
parameter (get an IllegalStateException because 'Config is Frozen') and 
tried to add a request attribute all by the name I have defined for the 
parameter (it happens to be 'method') and none of it worked.

So to recap if this isn't clear so far, going into my LDA to change the 
ordering is fine because its from a JSP link where a value for 
'parameter' is defined, so the LDA knows which method to call. However 
by the end of the "moveDown" method, where I need to send execution over 
to the "showList" method, I have no way to define a parameter value, so 
when the forward is returned, and execution comes BACK to the LDA, it 
has no parameter value (hence the exception). I've looked into using the 
"unspecified" method, but it SEEMS to me like that has the exact same 
problem... if no parameter is specified, I STILL want to forward to the 
showList method in the LDA, but I still won't be able to set the 
parameter, and it seems ugly to do a:

protected ActionForward unspecified(

   ActionMapping mapping,

   ActionForm form,

   HttpServletRequest request,

   HttpServletResponse response)

   throws Exception

   {

   

   return showList();

   }

Does anyone know how I would be able to forward from one method in an 
LDA to another method in the same LDA (or any other LDA for that 
matter...)? My entire site is a 1:1 mapping for actions and JSPs, so 
users never actually see ".jsp" in their address bar, its always ".do", 
so being able to go between LDAs is pretty important to me ;)

Thank you for any help you can provide!

UPDATE:
I just tried doing what I thought would be ugly:
protected ActionForward unspecified(

  ActionMapping mapping,

  ActionForm form,

  HttpServletRequest request,

  HttpServletResponse response)

  throws Exception

  {

  return showList(mapping, form, request, response);

  }

And it didn't work either, it threw the same exception, EVEN THOUGH the 
forward that returns from "showList" is actually pointing to a JSP page 
(not another Action or LDA like was my original problem). To be honest 
I'm not even entirely sure that my unspecified method got called, 
because the exception I get is EXACTLY the same... I'm using Struts 1.1, 
and I thought I saw somewhere in a longer thread from March I think that 
this didn't work in 1.1 but works in 1.2 (nightly build)?

Re: How to forward from one LookupDispatchAction to another LDA

[Riyad Kalla]

UPDATE:
Upgraded my Struts install to nightly build and now the code snippet 
below works. I'm still curious if anyone knows how one LDA can forward 
to another (or the same) LDA, even if it takes manually setting the 
parameter value (how?)

Thanks!

booya I really appreciate the code snippets and explination! I hadn't gotten 
involved in ActionForwards and appreciate you shedding light on the situation 
for me.

This EXACT same thing happened to me for about 3months. I thought I was going 
crazy... at first it was a annoying but I think many people would be 
surprised how descructive double clicking can be when its not indended when 
using an IDE or just working on your PC (accidentally moving the C:\Windows 
directory into the Program Files directory just because you tried to mouse 
over a directory and rename it).

The bluetooth desktop (mouth and keyboard) are very nice, I think you'd like 
them. But they are pricey.

IIRC its got a basestation you mount it on when you aren't using it that 
recharges it.

You can't go wrong with an IntelliMouse Explorer 3.0

I personally don't like Logitec, but that's only cause I've had a series of 
bad luck with their opticals (keep crapping out).

Oh that sucks... I thought there was a docking station, guess not!

6 weeks... that's kind of rediculous... common MS! Put a digital camera 
battery in it or something and give us a recharger.

Benefits of LookupDispatchAction without parameter nonsense

[Riyad Kalla]

Hey guys,
After playing with the LookupDispatchAction most of the day and converting 
over some existing functionality to using it, I've figured out that i love 
the consolidation of functionality into 1 class, but the problems I've run 
into (non stop) dealing with the parameter and making sure that all my 
buttons now have "property" values (which, for example, breaks some existing 
code like ) so that the LDA has a parameter to determine which 
method to call has gotten me really short on nerves.

Does anyone else have a nice clean way that they have consolidated all their 
CRUD functions into a 1 action, then found a nice way to delegate to the 
proper method based on say the URL that the user is trying to access (instead 
of the parameter value)?

Best,
Riyad

Re: Benefits of LookupDispatchAction without parameter nonsense

[Riyad Kalla]

Everyone thank you for the feedback, actually I tried the MappingDispatch and 
it seems to be just what I was looking for. You specify the method name IN 
the parameter... so you can set say 3 actions, with different paths, all 
pointing to the same type, and you specify the method to call in the param:

Re: How to get a value from the from bean

[Riyad Kalla]

If you are trying to print out the value:

where nameOfForm is the name of the form defined in your struts-config 
and passed in via the 'name' argument in the action for this page.

And use bean:define to create a page-scoped bean if you just want to use 
it places (like in calculations and such). Also jsp:useBean works too.

Struts Development seems slow, info?

[Riyad Kalla]

Hey guys,
I've been looking at this for a while as an indicator of a 1.2 release:
http://issues.apache.org/bugzilla/buglist.cgi?bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&bug_severity=Blocker&bug_severity=Critical&bug_severity=Major&bug_severity=Normal&bug_severity=Minor&email1=&emailtype1=substring&emailassigned_to1=1&email2=&emailtype2=substring&emailreporter2=1&bugidtype=include&bug_id=&changedin=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&product=Struts&short_desc=&short_desc_type=allwordssubstr&long_desc=&long_desc_type=allwordssubstr&bug_file_loc=&bug_file_loc_type=allwordssubstr&keywords=&keywords_type=anywords&field0-0-0=noop&type0-0-0=noop&value0-0-0=&cmdtype=doit&order=bugs.bug_id
and MOST of these bugs actually have solutions attached to them, but I 
noticed that (a) they don't seem to be getting closed out for months at 
a time and (b) I see the same developer name(s) over and over again on 
these bugs and (c) the communication over the bugs are not very verbal 
at all (slow)

And I know that all projects work differently, so I was wondering if 
anyone knew or heard (maybe even from the dev list) if there is waining 
interest in Struts and the devs are working on other things, or if the 
devs have always been this bad about communication?

Not to say that JSF is the future (I have no idea what will be) but if 
Struts development support is slowing down and people are starting to 
look else where, I'd just like to know for future-time-investment sake.

Thanks!

Ahh your query is a lot more impressive than mine ;)

and this bug:

http://issues.apache.org/bugzilla/show_bug.cgi?id=28150

took 11 hours to get applied from being submitted!

When  Struts 1 beta was released the servlet spec was 2.2. Since then (about
3 years I think) Servlet 2.3, Servlet 2.4 the JSTL and Java Server Faces
have all come along - in the next few years who knows what the best
technology will be to deploy - but it won't be the same as today (even if
its still Struts) and your going to have to continually re-invest in the new
stuff that comes along - all you can do today is decided whats the best
solution now.
 

Yes this is certainly true. But I felt we were at an apex right now, 
between Old/New... JSF being the new golden child that I haven't really 
seen anyone use yet so we could figure out if it really was going to be 
"all that"... I was just curious. Thank you for the feedback.

Re: i18n with keys from DB

[Riyad Kalla]

Unfortunately you can't use tags inside of eachother like that, which is 
why my code is still spackled with little expressions:



You can use an expression language to get around some cases like this 
with JSTL, and I think Struts supports the EL as well... I don't know 
for sure, I haven't used it.

Re: Struts Development seems slow, info?

[Riyad Kalla]

Steve,
Thanks so much for the reply. I wanted to clarify that I READ day-in and 
day-out those typical "whats going on with this project? I HATE YOU" 
emails, and I really didn't intend mine to sound that way. I was really 
just curious about what was going on because I was new to the list 
(thanks for the tip abou subscribing to dev, I'll do that today!)

comments below:

Steve Raeburn wrote:

Also, perhaps the question you should be asking is, "How can *I* help
speed things up?"
 

Nope, I'm pretty sure my original question is what I wanted to ask :D

Here's a couple of ideas:

- Try out the Stuts 1.2.0 release and report back any problems, or
(hopefully) report how stable and reliable it is for your applications.
- Get the source code and try applying some of those patches that you've
seen on the bug reports. Let us know whether they work for you.
There *has* been a first 1.2.x release, it's just not considered
production quality so we're aiming for a 1.2.1 release that hopefully
will be. Ted & Martin, particularly, put a lot of effort into getting
that release out, so it's not like there's nothing going on here :-)
 

Very cool I didn't know this. After hitting bugzilla with those queries 
I'm REALLY stoked for 1.2.x (800 bug fixes? Wow -- note I realize bugs 
== features in bugzilla and not all of those were defects)

One of the misconceptions about supplying patches is that once a patch
has been submitted, that's the end of the job. However, a committer
still has to:
   1) understand the original bug report and be able to reproduce the
problem
   2) apply the patch and *test* it for himself
this can be quite a lot of work, even if you the patch works as
advertised (not all do).
If you also go through that process and report back that it works for
you, the committers' confidence in the patch is increased. We still have
to do our own testing, but if your results match ours, then we can be
reasonably confident that the patch is good.
 

Yes I see your point, sorry for drawing such rash conclusions.

To address your points, specifically:

 

(a) they don't seem to be getting closed out for months at a time and
 

I don't think that's uncommon in any software project. Some things get
fixed quickly because they're easy or urgent; others take a while. Only
recently, I noticed a bug for Mozilla that has been open for 4 *years*
:-) That doesn't mean Mozilla is a bad product or isn't being actively
developed, just that they had other priorities.
 

Again, definately right. What triggered the questions was that I was 
using THAT list as a gauge to see when 1.2 was comming out, and for the 
last month (maybe more) that list has closed 1 bug and added 2... so I 
was like "what the heck's going on here with progress?". I had no idea 
about the already closed bugs, OR the dev lists... again, it was an 
uneducated comment on my part.

 

(b) I see the same developer name(s) over and over again on these
 

bugs and

So only a few people are doing all the work? And you wonder why
everything isn't done immediately!
 

Oh absolutely, I just figured with Struts being such a high profile 
project that there would be more people. So combined with my comment 
above, I thought most of the devs had gone onto something else, or 
stopped contributing... either way I was wrong and you are all working 
very hard.

 

(c) the communication over the bugs are not very verbal at all
 

(slow)

I don't agree with you on this (or maybe I misunderstand). Communication
on the Struts project seems to be very good, to me. We have an excellent
user list, an active developer list and lots of communication via
bugzilla. Don't forget that some discussion about open issues may move
from bugzilla to the dev list, or the user list. It's worth monitoring
dev, if you're interested in where things are going.
 

This is my mistake, I should have checked the lists.

Lastly, don't forget that nobody gets paid to develop Struts. We all
have to work full-time jobs to make a living. Struts is what we do for
relaxation on the weekends :-)
 

We ALL appreciate it, but this is also what probably all of us on this 
list, along with 20,000 other developers around the globe do on our 
weekends and for relaxaction and I think we would be thrilled if a 
community formed around any of our hobby projects (not to say Struts is 
a hobby, but you get the point).

Now everyone repeat after me, "The next version will be released 'When
It's Ready'" ;-)
 

That's fine by me, I almost went crazy trying to convince the NetBeans 
development team to adopt a release cycle like the Jakarta projects: 
release when the bugs are fixed. Then I finally realized that my efforts 
were equivalent to putting a saddle on a rock and trying to ride it in a 
race.

Again I really appreciate the reply, I'll get myself up to speed more 
approrpiately before asking sweeping questions like that in the future.

Best wishes,
Riyad

Re: please clarify my doubt on Struts Checkbox

[Riyad Kalla]

I had a problem like this too... and if you check the taglib API docs 
for checkbox, you actually NEED to set the checkbox to false in the 
reset() method in the form in order for it to work... in my case my 
default was checked, but I HAD to set it to unchecked in order for it to 
work... seemed like a strange design decision to me.

Then you can use Javascript to check the checkbox on load, but that's a 
PIA IMO.

Is MappingDispatchAction (Struts?) multithreaded? (Do I need to worry about it?)

[Riyad Kalla]

I'm asking because I am now getting into MappingDispatchActions (MDA), 
and almost all of my actions do some form of DB validation and error out 
if something goes wrong. So I have stamped all over the place 4 lines of 
code that look like:

ActionMessages actionMessages = new ActionMessages();
actionMessages.add(ActionMessages.GLOBAL_MESSAGE, new 
ActionMessage("product.error.cannotMove"));
saveErrors(request, actionMessages);
return mapping.findForward("failure");
And I was thinking how nice, performance and organization if I could 
move a protected instance or even utility method into a base 
AbstractMappingDispatchAction class that did those 4 steps for me and I 
just passed in the message key

So the method would do something like:

actionMessages.clear();
actionMessages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage(messageKey));
saveErrors(request, actionMessages);
return mapping.findForward(forwardName);
but then I realized that this could be a huge problem if I had (a) a lot 
of users using the system and (b) struts/servlet container was 
multithreaded and called 2 methods at the same time that BOTH had 
errors... I could run into a situation where one method cleared the 
errors that the other method was trying to return to the user because 
the actionMessages instance is shared per-class.

Can anyone let me know if my worry IS correct and I should keep 
everything the way it is, or if I'm safe and can go ahead with it, and 
"why", if you know.

Thanks!

Re: Is MappingDispatchAction (Struts?) multithreaded? (Do I need to worry about it?)

[Riyad Kalla]

Let me clarify:
The first sentence should read "and almost all of my METHODS in my MDA's 
do some form of...", so my question is pertaining to any danger I have 
when 2+ methods of the same MDA gets called at the same time and all of 
them want to return errors.

Also the subject had "Struts" in it, because I'm not sure if this is a 
"is Struts thread safe?" question or a "Does my servlet container 
determine if something is thread safe? And if so, is Struts?". So I'm 
not real clear on what takes care of threading, but I know the use-case 
I want and I'm curious if anyone knows if its not safe.

Best,

Re: Populating a form before displaying it

[Riyad Kalla]

Miguel,
I had this problem alot when I was developing a management system. For 
example, on my DeleteConfirmation pages, I wanted to show all the info 
for the entity I was erasing (for example, a User). So how I set that up 
was 2 actions in my struts-config:


   


   
   

So the idea here is that your first action is a pretty plain action that 
looks like this:

execute()
{
   UserForm userForm = (UserForm)form;
   userForm.setXXX;
   ...
   userForm.setXXX;
   request.setAttribute("userForm", userForm);
   return mapping.findForward("continue");
}
and when you get the JSP page, your userForm has been populated with all 
the necessary info.

Hope this helped,
Riyad

Re: Populating a form before displaying it

[Riyad Kalla]

Just to follow this up, the reson this works is that struts uses the 
'name' of the form from your struts-config to store the actual object 
under in the request or session scope, so as long as you keep your 
naming synced up you can also duplicate this behavior, like I did below 
when I populated the userForm OBJECT and then stuck it back into the 
request with the "userForm" key, because in my struts-config, I had an 
entry like this:

   ...

Hope this helped a little more ;)

Miguel,
I had this problem alot when I was developing a management system. For 
example, on my DeleteConfirmation pages, I wanted to show all the info 
for the entity I was erasing (for example, a User). So how I set that 
up was 2 actions in my struts-config:


   


   
   

So the idea here is that your first action is a pretty plain action 
that looks like this:

execute()
{
   UserForm userForm = (UserForm)form;
   userForm.setXXX;
   ...
   userForm.setXXX;
   request.setAttribute("userForm", userForm);
   return mapping.findForward("continue");
}
and when you get the JSP page, your userForm has been populated with 
all the necessary info.

Hope this helped,
Riyad

Re: ApplicationResource.properties reload

[Riyad Kalla]

If you are using Tomcat, it should reload this automatically if you have 
"reload properties" selected for your context (Atleast mine does while 
I'm wokring on the ApplicationResource file), and if all else fails, 
just use the Manager to restart the context (takes about 1 second).

Re: ApplicationResource.properties reload

[Riyad Kalla]

Use the administrator, its easier :)

Make sure you have setup an "admin" and "manager" Account in your 
tomcat-users.xml file per the tomcat docs. Then go to 
http://localhost:8080 while Tomcat is running, and click the 
Administrator link. Expand the host link (I believe it is) and drill 
down to your context, change the options there and save/commit them.

Re: ApplicationResource.properties reload

[Riyad Kalla]

The properties file will be reloaded by the servlet. i'm not sure what 
you mean by "changed" in this context, it needs to be re-read if it is 
modified.

If the properties class is loaded, which I assume it is, the file

Re: reloading Actions

Tomcat 5 seems to do this for me implicitly... reloads all my classes

daos, etc.)

Re: reuse of request parameter in application flow

[Riyad Kalla]

Samuel,
I've had this problem as well and what I ended up doing was to add 'hidden' 
tags to the top of my html:form element that encapsulated the parameters that 
I wanted to persist to the next page. Something like:




...
User Name: 
Join Date: 
...
 


I'm not aware of another way to do this that is 'hidden' to the user while 
still keeping the vars in your request scope, just because of the way HTTP 
works.

Best,
Riyad

Re: equal tag question

[Riyad Kalla]

Using the dot operator to separate method calls should work:


This user is currently Inactive



That should call:
assignUserForm.getAssignUser().getName(), and then compare it to "Bob".

If the above doesn't work, then pretend someone else told you to do it.

Re: how to read ApplicationResources.properties from a servlet

You could subclass the ActionServlet with your own instance that in its init

I think this should do the trick, please fix the path when necessary:

you could probably break that into multiple lines to make it easier to read.

Re: [OT] intern(): setting pooled String values

[Riyad Kalla]

IIRC interning of Strings has been implied String behavior since the Java 1.2 
VM.

For example:
String one = "ham";
String two = "ham";

if(one == two)
System.out.println("Same!");

will print 'Same'.

Re: concurrency in struts

[Riyad Kalla]

This question is actually what made me sign up to this mailing list... 
the answer is that there is no implicit concurrency. All your 
work/variables in Actions should be method-scoped and not use ANY class 
variables because of this. My specific questions was that I wanted to 
use a class variable "ActionErrors" so any of my methods 
(DispatchAction) could add errors without initializing a new ActionError 
instance, and return it. But this is incorrect and can/will introduce 
problems.

So there is no concurrency in Struts.

Re: bean:write removes double spaces

[Riyad Kalla]

You'll have to intercept the spaces and covert them to  's, atleast 
this is what I have had to do.

Brad Balmer wrote:

This isn't a struts issue as it seems to be an issue with how browsers

I'm using bean:write to display a variable to the page.  The problem 
is that the value sometimes contains double-spaces which are being 
displayed as a single-space.

Does anybody know of a way to defeat this WITHOUT wrapping the value 
in a  tag?

Thanks.

Re: Remembering form values across requests

[Riyad Kalla]

Hmmm I would think that html:reset would tie into the Form.reset() 
method, but you said you are using a DynaForm so I'm not sure how that 
would work (I hard code all my forms because I like wasting time :)

Michael Weaver wrote:

I am new to Struts and have tried to used a DynaActionForm to hold the users form choices across requests by setting the form to session scope. This causes a problem with html:reset since I get back the same values on reset and in effect nothing is reset. I could be committing a big design no no here. Maybe I should be using a different bean to hold the form choices across requests but it seems redundant. Any thoughts on if this is a misuse of forms or not would be appreciated. If someone can point out a repository of programs demonstrating good Struts usages that would be helpful also.

Re: Is MappingDispatchAction (Struts?) multithreaded? (Do I need to worry about it?)

Most of the aspects in which you have to worry about thread safety in 
Struts mirror those you have to be concerned with in servlets.  In the 
particular case of MapDispatchAction, though, there is nothing really 
special about it (in terms of thread safety) versus any other Action.

Struts creates one instance of an Action per  element in a 
struts-config.xml file.  If there are multiple simultaneous requests 
to the same action (very common in an app with lots of users), then 
you do indeed need to care about this.

The most important rule -- again, this relates to *all* Actions, not 
just MDAs -- is to *never* use instance variables in the Action class 
to store information related to the state of a particular request.  
Instead, you should use local variables inside your methods, and pass 
whatever data you need to other methods in the class via parameters.  
Why?  Because local variables and method parameters exist once per 
*thread* instead of once per *instance*, so there is no problem in 
using them to store the state for a particular request.

Thus, you are definitely correct in being concerned about thread 
safety of the proposed code.  If the "actionMessages" variable is 
coded as an instance variable of the MDA, it will be updated by all 
simultaneous requests to the same action (it only takes two 
simultaneous requests to ruin your day).  You'll want to come up with 
some mechanism that passes all the necessary data as parameters, and 
not rely on instance variables.

I'm asking because I am now getting into MappingDispatchActions 
(MDA), and almost all of my actions do some form of DB validation 
and error out if something goes wrong. So I have stamped all over 
the place 4 lines of code that look like:

ActionMessages actionMessages = new ActionMessages();
actionMessages.add(ActionMessages.GLOBAL_MESSAGE, new 
ActionMessage("product.error.cannotMove"));
saveErrors(request, actionMessages);
return mapping.findForward("failure");

And I was thinking how nice, performance and organization if I 
could move a protected instance or even utility method into a base 
AbstractMappingDispatchAction class that did those 4 steps for me 
and I just passed in the message key

So the method would do something like:

actionMessages.clear();
actionMessages.add(ActionMessages.GLOBAL_MESSAGE, new 
ActionMessage(messageKey));
saveErrors(request, actionMessages);
return mapping.findForward(forwardName);

but then I realized that this could be a huge problem if I had (a) 
a lot of users using the system and (b) struts/servlet container 
was multithreaded and called 2 methods at the same time that BOTH 
had errors... I could run into a situation where one method cleared 
the errors that the other method was trying to return to the user 
because the actionMessages instance is shared per-class.

Can anyone let me know if my worry IS correct and I should keep 
everything the way it is, or if I'm safe and can go ahead with it, 
and "why", if you know.

Bill this will depending totally on the browser how 'broken' or 'unbroken' the

Re: struts repopulate bug?

[Riyad Kalla]

Dana,
Yes Struts should and does do this. It actually does this so well, that 
for login forms you need to manually clear the beans or else it 
repopulates the values :)

1) Are you syncing up the names/properties of your fields on your JSP 
page in the form with the property names of the Form?
.. Java snippet ..
public String getUserName();
public void setUserName(String userName);

... JSP Snippet ...

2) Did you implement your reset method cleanly?

3) Is your validate method straight forward?
if(userName == null || userName.length() == 0)
 // make/add some errors
return actionErrors;
4) How is your action defined in your struts-config? Did you specify a 
scope for the bean? Have you tried NOT specifying the scope?

I want to reassure you that Struts does this very well and doesn't need 
you to hack around it, so if this is not working for you, we just need 
to keep trying.

request.setAttribute(,this);

This made everhything work, so my question is, why the hell didn't struts do this?  Isn't it supposed to?  Is there anything I could have done to make struts not do this, or maybe place a different form bean instance on the request?  It works now, but I don't like hacks.

Good that your errors are being displayed, and no I don't think the 
scope of the form should matter, jsut for sanity sake remove the 'scope' 
attribute from your action in your struts-config. If you can narrow this 
down to a small test case: 1 jsp, 1 form, 1 action, 1 struts-config, you 
can post them here for us to look at.

Hi Dana,

If I had only one guess as to the problem, I'd say there was a mismatch
between a JSP tag versus what was defined in struts-config. I've found my
silent errors most often trace back to JSP tags. This could be scope-related
but is more likely the name. The name attribute of the action tag
(struts-config) must match the name attribute of the form-bean tag
(struts-config). The action attribute of the html:form tag (JSP) must match
the path attribute of the action tag (struts-config). If the html:text or
other output elements are Struts tags and inside the form tag, you won't
need to specify the name attribute, just the property attribute. The JSP tag
names are often derided as poorly named.
Basic requirements for keeping an ActionForm contents:
- Must have your ActionForm defined in struts-config.xml
- Action must have this ActionForm associated in struts-config.xml.
- You should work with the ActionForm passed into the action.
- You should have an  tag configured to point to an action with
the form declared. (Don't forget to define the html JSP tag name.)
Beyond that, you might also compare your struts-config, jsp, and action to
some existing samples. I use the feature you mention in every one of my many
Struts modules and it works perfectly for me.
If you could give more concrete examples from the struts-config.xml, JSP,
and action files, we could probably be more helpful. Helpful stuff from
struts-config: your form, action, and action-mappings; from the JSP:
html:form tag and any fields, along with the definitions at the top. The
execute/perform method of your Action.
FYI: To know whether you're redirecting to the form, the form mapping must
have a redirect=true attribute in struts-config.xml.

This isn't a problem at all. I do this now with a page that builds

them, then the page reloads with another section showing asking for more 
user input. I guess its kinda like a 1-page wizard.

Re: Clearing Input fields

[Riyad Kalla]

If it needs to be cleared every time, why not just reset the form before 
going back to the page? I had a problem similar to this w.r.t. to a 
login page, it was unsafe because if someone logged out, their login 
info was automatically populated back into the form. SO if they walked 
away, another user could walk over and hit enter and login as the person 
that just left. So I introduced an action that did a forward to the JSP 
page, but before it did it calls:
form.reset();

then forwards, so the form is always cleared.

Hi Brian,
If you view the html source, you will see the value='x'.
Clicking on Reset button is initializing to this value for each field.
I have solved this problem by replacing Reset button with button and
onclick event javascript for that button which will clear all fields.
Let me know if you need generic javascript which only needs form name
to clear all fields.

Re: Clearing Input fields

[Riyad Kalla]

Brian you can either use 1 action, and parse the submit button values to 
determine what code to execute, OR you can use 2 seprate forms and actions, 
OR you can put all related actions into one MappingDispatchAction or 
LookupDispatchAction.

If you don't want to get into DispatchActions then I'd suggest the 2nd one, 
its very clean and straight forward. You have 2 execution paths, so you have 
2 actions and 2 forms. If you hide 2 actions in 1 action, it might be less 
clear.

The only thing here is that you will likely need to stick the forms in 2 TD's 
in an embedded table so they appear side by side, instead of ontop fo 
eachother.

Re: [OT] Production app server

[Riyad Kalla]

Why not use Tomcat 5, and increase the memory that the server uses?

I don't know that many people that took Tomcat 4 seriously for production in 
its early stages, usually preferring Resin. However as 4.1.x stabalized and 5 
came out, it seems its a non-issue anymore... I don't see the holy-wars that 
I used to.

I'd suggest to deploy with what you are farmiliar with. If the system crashes 
6 times a day and kills a dog, then look at changing to a totally new app 
server ;)

Re: [ot] eclipse vs. IDEA

[Riyad Kalla]

IDEA (Swing) currently performs better on Mac and Linux because (a) IBM 
is dragging their feet getting the performance of SWT up to par on those 
non-Windows platforms. There was a HUGE stink about Linux performance, 
starting here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=37683, that 
resulted in major reworking of some key parts of Eclipse which will make 
3.0 much faster on all platforms, but that is still 1/2 as fast as Windows.

Also keep in mind that the JetBrains team is some of the sharpest and 
most systematic guys you'll ever meet. IntelliJ is an application with 
some of the finest tuned Swing programmer just about anywhere and the 
end result is a fantastic IDE.

If you have to use Eclipse and IntelliJ for 6 months each, I think you 
would fine IntelliJ is a much nicer IDE. "It Just Works" is a phrase you 
will find yourself using a lot. If you are doing JUST Java programming, 
you might be hard pressed to make a differential bulleted list, but if 
you are doing development (Java, Swing, JSP, Servlets, HTML Files, XML 
Files, DTDs, Schemas, TLDs, etc. etc. etc. etc.) you will spend most of 
your day trying to find half-finished plugins for Eclipse to do all of 
that (except the Java programming) while IntelliJ will offer you far 
superior support for these technologies by default. Also if you take the 
time to watch the viewlets for the GUI builder, I think you'll be 
pleasently surprised how powerful it can be.

If money isn't an object, and you are the kind of person that 
appreciates polish and attention to detail (I'm assuming you are, since 
you are on Mac already) then you have already selected IntelliJ. If you 
are a pretty nuts and bolts developers that loves free stuff and can 
stand needing to search for a plugin to give you missing functionality, 
and even then maybe not have the best support for it, then Eclipse is 
your choice.

Pound for Pound comparison of pure Java programming might be tight 
between the two, they are both *fantastic*, but once you start asking 
about other technologies and the like, then the arrow just points more 
and more to IntelliJ.

I hope this helped... I'm a bit passionate about IDEs :)
Best,
Riyad

Re: connection pooling

If your pool max is 4, then you will see 4 and your 5th user will wait 
until someone returns their connection to the pool.

Re: Multiple Databases.

[Riyad Kalla]

IIRC you should use the connection pool mechanism of your App Server and 
not Struts... I believe its use was deprecated (someone please correct 
me if I'm wrong).

Re: Compressing your struts for faster transfer

[Riyad Kalla]

It is very cool, but expensive for server resources (like SSL). So if your 
server spends most of its time sitting around, compression can be a nice 
addition.

Q: Can I have multiple ApplicationResources from the same locale?

[Riyad Kalla]

This may be a RTFM situation, but I didn't want to take a break and try it and 
then after a hour find out it didn't work so I was hoping (while I was 
coding) someone could let me know if the following is legal:

Situation:
I have an ApplicationResources_en.properties file that represents the English 
locale of my app. This file is getting huge (to say the least) as I've 
internationalized pretty much all the text in my entire app. I was hoping to 
break out this file into logical units that collective represented the 
English locale, for example:

ApplicationResources-User_en.properties
ApplicationResources-Product_en.properties
ApplicationResources-Module_en.properties
ApplicationResources-Administrator_en.properties.

and move the corresponding key/value strings into the appropriate .properties 
files. But then I had a question about how my message-resources tag in my 
struts-config file should change... it currently looks like this:


Thanks for any help you can provide.

How long are your struts-config files? Should I worry about performance?

[Riyad Kalla]

I'm curious what the size of some of the verteran programmer's 
struts-config.xml files are. Mine is approaching 2k lines right now, and I'm 
about 1/2 done with the project I'm working on.

I don't know if I should really start worrying about performance/other issues, 
or if this is normal and I should smile and keep working.

Thanks!

Ok this was what I was wondering about (runtime). I didn't know if the

to that effect.

Re: message resource problems

[Riyad Kalla]

I believe if you have more than one resource file, you need to give them keys. 
The resource file with no key becomes the default, and then the others need 
to be referenced explicity using the "bundleKey" (I think that's the name...) 
attribute of the struts taglibs.

Re: version confusion

[Riyad Kalla]

Brian,
This can definately get confusing if you are just thrown into the mix. 

Tomcat 5 is definately the right way to go, its faster, more stable and 
supports newer specs. Struts, IIRC, is designed to only need the Servlet 2.2 
and JSP 1.0 or 1.1 spec, it was meant to be super-compatible, soyou should be 
safe.

There is information on the Struts page (under future direction) where it 
explains that the next Struts 2.0 release might change to require Servlet 
2.3/JSP 1.2 I believe it was.

As far as JSTL, just get the newest version possible. JSTL it a set of 
taglibs, and JSP has supported taglibs for a while. But if you want to get 
fancy with the Expression Language support in JSTL, then you will need a 
container that supports Servlet 2.4 spec (which Tomcat 5 does just fine).


I believe I've left out gaping holes of information, and may even be wrong, 
but AFAIK this is the gist of the version information you need. Generally 
going with the newest stuff you can find is pretty safe, especially with 
Jakarta projects (stuff comming out of apache group). They have one of the 
strictest (I love it) release cycles I've ever seen when it comes to shipping 
stable stuff.

I hope that helped atleast a little,
Riyad

None,
That was EXACTLY the kind of information I was looking for! Thanks for the 
deatiled answer.

My god that homegrown framework must have been a beast to convert, but I bet 
the app is sure happier now that its using Struts.

Re: How long are your struts-config files? Should I worry about performance?

[Riyad Kalla]

Jose thank you for the detailed info, definately larger than mine!
When I first read your email, I thought that "19,35,4,41 Kb" was one 
number, and I was sitting there scratching my head trying to figure out 
what Locale you were from :D

performance?
My config file for a project I'm currently working on is 7k,
and that's NOT
counting comments (something like 16k counting them - I'm a
comment freak).
Since it's only parsed once at startup, I wouldn't be too
overly concerned
about performance.  Yes, your talking about a lookup for each
request, and
I'm not familiar with how it's stored internally (just a
HashMap maybe?),
but I wouldn't suspect it's a huge concern.  I can't speak to
how typical
that size is of course, but it's one example.
I should also point out that the app I'm referring to was
originally built
on a homegrown framework (I didn't write it, so don't laugh
at ME when I
tell you this)... it used a very convoluted mapping XML file
structure, much
more complex than struts-config, and the that version of the
file was 43k!
Again, NOT counting comments!  And to make matter worse, this
file was
actually parsed WITH EACH REQUEST!!  But, and here's where I
get to a point
(aside from the fact that those that wrote that framework
didn't know their
a** from their elbows)... performance even under those
conditions with a
halfway decent load (50 concurrent users at any given time on
average) was
perfectly acceptable.  And it wasn't a monstrous server either (Dual
P2-550's with 1G RAM and a SCSI array internally).
So, I wouldn't be too concerned with the size of your
struts-config, unless
someone else has reason to disagree.  A couple of K wouldn't
concern me.

Re: Session size

[Riyad Kalla]

Mike,
Good suggestions. I was dealing with something like this recently and decided 
that for me, adding caching at the DAO level:

e.g. List userList = UserDAO.getAllUsers();

would offer the biggest performance benefit since it would be:

(a) application wide, instead of per session
(b) returned Lists are 4-byte pointers to the actual list object cached in the 
DAO
(c) The DAO itself handles all manipulation of those types, so it knows when 
to invalid its own cache (on inserts/updates/removes)


What do people think about this strategy? (Before I spend a week implementing 
it :)

Best,
Riyad

Re: Session size

[Riyad Kalla]

Larry,
It depends on how you load the elements. If you are creating the smaller 
objects by first loading the full objects, then just save the time and use 
the full ones.

If however you are loading the DisplayObjects directly via a Hibernate query 
of course that will be magnitudes smaller.

Also you may consider what the average size of your 200 Strings are. If its 
around 24 characters each (maybe a name, or name of something) that's say 
roughly 30 (object overhead is probably more) x 200 = 6000 bytes (6k) and 
maybe as high as 8k for overhead (I'm pulling numbers out of air here, I 
don't know the VM details on this). Where as your 5-string object is going to 
be considerably smaller (30 x 5 = 150 bytes, ~0.15K).

I'd say if you can load the DisplayObject directly from the DB with a query, 
definately do that, especially if your employement trees can get large (100s 
or 1000s).

Best,
Riyad

Re: Are there any IDE's that understand Struts tags?

I second this especially if you are doing Struts. MyEclipse offers wizards, 
visual flow navigation and manipulation for your Struts apps which is quite 
nice and of course JSP autocomplete, debugging, taglib autocomplete, xml 
autocomplete, etc. etc.  all the bells and whistles.

** Disclaimer: I help with support on the MyEclipse forums. If you have any

Re: Session size

[Riyad Kalla]

Hmm, I should clarify what I meant:

The DAO will be at the application scope, so if you cache say the last 50 
queries, the cache is held at application scope. In your case, this will 
still help. 

Lets say you have 20 users all working on the site, they all hit their "Show 
employement Tree" page, and you hit the 
UserDAO.getEmploymentTreeForUserID(int userID) method for all 20 people with 
different ID's. That will perform 20 separate queries, cache the result, and 
return it.

Now when all those users hit the refresh button on their web page, it hits 
your DAO again, the same method, with all 20 separate ID's again. But this 
time, all 20 of them are successful cache hits and are returned immediately.

Now say users 1-5 log out and come back 2 hours later and check your 
employement tree page, IF their list had been stored in their sessions, that 
would require you to hit the DB again to reload the lists, but because your 
caching the results in your DAO itself, all of those 5 users that came back 
and check their employement tree, are getting all their results from the 
DAO's cache again since it was stored at the application level (the cache is 
still valid).


The other sexy thing is that if someone calls UserDAO.removeUserByID(4) or 
something liek that, your DAO knows to either (a) aggressively invalid all 
the cache and have all caches rebuilt, OR (b) you could take some time to 
intelligently remove that user from all cached values if it was import to you 
to keep your caches full.


It just gives you more options since all your cache building/invalidating 
occurs in the same DAO class, instead of needing to worry about synchronizing 
multiple resources and classes with eachother.

Did that make sense?

Best,
Riyad

Yes absolutely a concern, which is where you can tune how big your cache for 
DAO is. For example, UserRoles might be cheap/small objects, so your cache 
can be 100 units big, and your Users might be expensive/huge objects, so your 
cache only holds 20 units... something like that.

Doing analysis on the memory requirements is a good idea. Considering that 
your users (200 of them) takes up 8k, that's nothing to a server with 2Gig of 
ram... so you could probably increase this to hold a cache of 100s of users.

Hmm yes, if its important to keep the cache as intact as possible, then 
applying logic during table mutations is important.

>

Object pooling is more generic. The idea being pooling is to store objects for 
reuse usually in the pattern of (1) reinitialize/clear object then (2) 
repopulate and use it (3) return it to the pool.

Where in this case we want to create our objects, and then keep them in their 
same state before reusing them, we aren't really returning them to a 'pool' 
to be pulled out again and reinitialized.

Specifically, when we read in a UserDTO lets say (Data Transfer Object), we 
want to keep his data untouched (e.g. Name="Bob", Age="32"). After displaying 
Bob's data, we don't return his object to a pool, we keep it around in a 
cache, so when someone says "Hey give me Bob's record" we've got it handy 
without hitting the database again.

But yes, caching and pooling are definately in the same family of 'strategies' 
for program performance.

Re: Best way to connect to Database in struts

[Riyad Kalla]

Ditto to this comment.

DB > Tomcat JNDI Context > Hibernate > Struts


Tomcat JNDI will manage the connection pooling to the DB for you, then 
hibernate will use the pooled connection to perform queries against, and then 
in your struts app all you do is add/update/remove your objects directly 
using hibernate.

Very slick stuff. I would suggest that you still make use of DAO's to 
centralize and hide the Hibernate query details from your Struts actions.

Re: Multiple submit buttons in the same form

[Riyad Kalla]

1) Yes you can do it
2) Given each button a different value, like "List Products" and "List 
All Products"
3) Add a "buttonValue" (or some other adequetly names) property to your 
form for the respective action, it will capture the button clicked.
4) In your action:

if(form.getButtonValue().equals("List Products"))
   // do stuff
else if(form.getButtonValue().equals("List All Products"))
   // do more stuff

Re: Multiple submit buttons in the same form

[Riyad Kalla]

Rick,
This is a great approach as well and I think we've giving good answers. 
1 way you change the Form, and another way you change the Action.

I didn't know you could do it the way you described, thanks for the tip!

You can do it much easier using either of the approachs below:
1) Use the LookUpDispatch Action. You simply give the submit button 
your dispatch property name (ie property="UserAction" ) then the value 
of the button gets looked up from a map in your LookUpDispatchAction 
(see the docs). Much cleaner.. although..

2) I still prefer to set a hidden variable of a dispatch Action with 
javascript when a button is clicked. Then simply use a regular 
DispatchAction or someone mentioned even a MapplingDispatchAction 
which I wasn't aware of (maybe this later is in Struts 1.2?). Assuming 
a regular dispatch action you have buttons like..

Update 

Cancel 


Then just make sure you are using a DispatchAction. (In the above it's 
better if you use the resources properties file for you button names: 
 Just in case later the button 
names change, it's easier to modify one resources file.

Re: Page pre-processing

[Riyad Kalla]

Eric,
I have something exactly like this, and I get around it by setting the 
action's validate attribute to false for the "prepare" method, and true 
for the "submission" action... for example:

prepareEditUser: takes a user ID, loads all data up into request for JSP 
page to show, action does validation on the ID, form validate == false;
editUser: form validate == true, accepts all params from the edit page 
and verifies that they are sane.

So with the validate = false action, the form won't validate, you just 
have to move the check into the action then you can reuse the form.

Eric Fesler wrote:
Hi,
I'm currently working on an application with several pages having
multiple combo-boxes.
The content of the combo-boxes is closely related to other components of
the model. Therefore, I use a 'prepare' action to setup the model and
put the combo-box collections in the request scope.
Unfortunately, this way of working is not compatible with the Struts
validation process. Indeed, when the validation of the form failed, the
request is forwarded back to the input page and the collections are not
initialized.
A workaround would be to put the collections in the session scope (what
I finally did) but at the end the session becomes full of garbage
information. Another solution is to build the collection within the JSP
page (maybe with custom tags) but this is against the separation of the
view and the model.
I was wondering if anybody had already thought about an additional
parameter linked to a struts-forward allowing page pre-processing. This
parameter could point to a new kind of model action that will complete
the model with information needed by the view any time the forward is
activated.
Or... I'm missing something ...
How do you handle such a case?
Thanks,

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

[Riyad Kalla]

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

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.

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.

OT: Is taglib execution between start/end tags need to worry about synchronization?

[Riyad Kalla]

I have a situation where my taglib is pretty expensive in that its 
execution looks something like this:

startTag()
* get ID passed in as attribute to tag
* lookup object in App scope with that ID (Search list)
* look at object and get 2 dependency IDs from it (statusID and typeID)
   * lookup the Status object in the App scope using the statusID 
(Search list)
   * lookup the Type object in the App scope using the typeID (Search list)
* print some stuff to output stream
   
* print the end of the stuff to output stream


So everything with a asterik (*) before it is done in the taglib, and 
the "Search list" denotes that I'm getting an ArrayList from the App 
scope, and then searching it for the object with the ID I'm interested 
in. Now when I ran some load tests on this tag, it was understandably 
not as fast as I had hoped, so I thought to speed it up, I would 
remember the last ID asked for when I return from the tag, and if the 
NEXT TIME the tag is executed, the same ID is asked for, I just reuse 
the object, its status and its type that I already found the previous 
time the tag ran, so ti looks something like this:
* get ID passed in as attribute to tag
** if ID is the same as the last ID we processed, jump right to the printing
   * lookup object in App scope with that ID (Search list)
   * look at object and get 2 dependency IDs from it (statusID and typeID)
   * lookup the Status object in the App scope using the statusID 
(Search list)
   * lookup the Type object in the App scope using the typeID 
(Search list)
** previousID = ID
* print some stuff to output stream
   
* print the end of the stuff to output stream


The lines with douible asteriks is the new code that remembers the last 
ID. Now this seems to work just fine and sped things up by about a 
factor of 5 for me, but I'm wondering if I need to worry about any 
potential synchornization issues... I was thinking no, because it seemed 
that another call wasn't going to come into this tag until the doTagEnd 
method had been called, then it would be put back into the Tag pool for use.

Can anyone let me know if this is fine, or if I need to go back to the 
old slow way because this will totally break with multiple people on the 
same page using the same tag at the same time?

TIA!

Taglib: how do you call a method like java.util.List.size() from the property of a tag?

[Riyad Kalla]

I'm trying to do something like:

   

but I'm obviously getting an exception on size because it doesn't follow 
JB naming conventions. How do I call this method? Do I NEED to use EL 
for this?

Re: clearing an ActionForm from session

[Riyad Kalla]

You can forcibly remove it as the last step in your last action before 
sending the user to a success page:
request.getSession().setAttribute("formName", null);

where "formName" is the same name you gave the bean in your 
struts-config.xml file in the "form-beans" section of the file. There is 
no automatic way I know of that you can tell Struts to destroy an object 
on purpose.

If you just want to reset the form, and not null it out, make your last 
line instead of the setAttribute, make it:
form.reset();

this way the form is still cached for use, but values are empty.

Thanks in advance.

Re: Taglib: how do you call a method like java.util.List.size() from the property of a tag?

[Riyad Kalla]

Hey Joe that length function looks like just what I wantedI didn't 
want to do scriplets because of the possibility of a NPE if the session 
timed out and the list wasn't in the session, I want something that 
gracefully handles the missing item and I thought a custom taglib might 
be overkill.

Thanks for your suggestions!

One of the unfortunate shortcomings of the Collections APIs is the 
lack of a bean-convention-named method to access the length of the list.

If you put userList into the request before forwarding to the JSP, you 
could also set another request attribute with the size value; or you 
could put the list in a simple wrapper:

public class MyListWrapper {
  private List list;
  public MyListWrapper(List list) { this.list = list; }
  public int getSize() { return this.list.size(); }
  public List getList() { return this.list; }
}
If you are using JSTL 1.1, you could use the "length" function.
http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/fn/length.fn.html
Of course, you could use scriptlets too.

Re: [Raw newbie] Struts/JSTL - A cople of urgent question (Message resources)

[Riyad Kalla]

This doesn't necessarily sound like a Struts question, so I'll answer it 
in the general terms:

1) Create your ResourceBundle for that properties file containing all 
your measurement information, then from that get the enumeration from 
"getKeys" then cycle over the keys getting the values, doing your logic 
on each value (if contains DISTANCE then blah).

2) You can call get normally here but when you get back your result, 
call a string.split(",") on it to get back a 2-element array, one with 
"en_US" in it and the other with "USA" in it, then you do your logic to 
make one the display variable and one the logical variable in the 
system. NOTE: String.split is insanely fast, actually all of the regexp 
package is insanely fast, I tried benchmarking it once to see if I 
should implement a much simplier routine for my parser, and the regexp 
package blew me away, it was almost rediculous how fast it was.

As a RAW newbie:
How do I buid an ArayList of properties for a menu?
for example;
I have a resource file containing:
DISTANCE_MILE=Mile
DISTANCE_KILO=Kilometre
DISTANCE_FEET=Feet
DISTANCE_METRE=Metre
AREA_SQ_FOOT=Sqare Foot
AREA_SQ_METRE=Square Metre
VOLUME_QUBIC_INCH=q'
VOLUME_QUBIC_METRE=m2
now, I need to (from a class), get the resource bundle and build an
araylist of (key, value) for DISTANCE* so that only the distance
parameters show up in my list.
To do this even more trickier if I have something like:
LANG_EN_US=en_US, USA
LANG_EN_UK=en_UK, England
...etc
how do I have the en_US (constant) as the value and USA (variable,
depending on language) as the display?
get my drift?
Thank you for a wonderrful forum (MSDN, go suck eggs!)

Re: Front Controller?

[Riyad Kalla]

Model 2 / MVC / Front Controller are all the same thing. In Struts the 
"Front Controller" is the "ActionServlet", it 
receives/handles/dispatches every single request that comes into your 
web app. You write actions that are like units of functionality, then 
specify in a mapping file the relationship between URLs and the Action, 
then depending on where the user is going, the ActionServlet will call 
the appropriate Action at the appropriate time to handle the user's request.

Hi Riyad,
here is a simple example:

 

I feel foolish, this is exactly what I wanted and didn't even see that 
in the taglib docs. Thanks a million!



BTW, you are doing a very good job on MyEclipseIDE Team!
 

Thank you, I appreciate that. They are a great/strong team to work with.
Best,
Riyad
