Displaying non-String properties of beans

[Rick Reumann]

I'm sure this question has come up but I'm not having much luck search
the archives. I'm really new to Struts so I hope this question isn't
too out of place for this list. Lets see we are dealing with Employee
beans.
I like to have my EmployeeBean maintain the datatypes of the members
to not have to all be Strings. (In this example say Age would be an
int, birthDate a java.util.Date, etc.). Now in my sample app I'm
practicing with I have an EmployeeForm class also that currently has
just String datatypes for these fields.  Having the information from
the actual form jsp's going to the EmployeeForm in as all Strings
without any conversions is not that big of a deal since wherever I do
anything with this data (jdbc inserts in the business logic I could
always covert them there if I need to ). However, I'm more concerned
with getting this information out and to display using the tags. For
example, say I have on an Action class that gets back and ArrayList of
EmployeeBean objects and puts this list into the request before
forwarding. I assume I can't do:









since I won't have birthDate formatted correctly, or say I was
returning a Double that I needed in a currency format. What is the
best way to deal with this situation?  I could of course maybe have my
business logic return me a Collection of EmployeeForm beans instead
and inside the EmployeeForm beans there would be methods like
setBirthDateDate( Date date ) that would take a java.util.Date and format it into
a String and then call the EmployeeForm setBrithDate( String date ).
Although that would work, I'd still rather deal with the business
logic that returns a Collection of EmployeeBeans... as this seems to
make the most reusable sense (maybe the components later won't just be
for the web).

Thanks for any help.

Migrating an existing architecture to Struts

[bhatia10]

I have a servlet based application, that uses client side xml parsing to
generate html served on the IE browser using xsl. It is quite tedious to
maintain this application (i have inherited it without support and it is a
modest size application). it is frames and lots of Javascript.

Anyways, the model is a single servlet application that uses POST for login
and GET for everything else. What my question is that I am considering
applying the Struts MVC-2 structure, I have studied MVC and understand how
the architecture works.

I wanted to get the opinion of users on this list to please share their
views on their projects of migrating an existing architecture to Struts. In
terms of

* how difficult was it
* is it worth the time and effort
* any pointers??
* in view of the articles written on structs, any online on migration?

I would appreciate your answers and I believe that it would help other users
too.

Re: Need example on using roles in struts-tiles

[Reynaldo Timonera]

Thanks Ted.

We are using database-based authentifiication -- we store our user and role
in a database. We retrieve these user and role info everytime the user logs
in and place the info in session scrope. I was thinking  if we can set the
isUserInRole according to the user's role from the database and not from the
container's web.xml. So I guess the question would be: is it still possible
to use the security role of tiles for this setup -- database-based.


Thanks again,

Reynaldo

Re: source generator

[Michael Grafton]

Hi Annie,

I looked into doing this a while ago, and found out there is tool for
generating EJBs from an existing database, called Middlegen:

http://boss.bekk.no/boss/middlegen/

It's somehow hooked up with XDoclet, which has the ability to generated
Castor value objects I believe.  So even though you don't need EJBs it
seems that somehow you could go from Oracle->Castor.  But you'd have to dig
a little deeper than I did.

RE: Accessing action object inside the form bean

[Javier Campoamor]

You can also use a promptAction, to populate the form with the values that
you want, before putting it into the request. Some thing lije this:
PromptAction(Populates the form with default values)->ActionForm(Gets the
user input)->DoAction(Process the form)

Re: self.close() exception

[Adam Grohs]

Bhaskar,
To the best of my knowledge, this approach outlined below has several
minor flaws.  First, it is not possible for the javascipt self.slose()
method to throw a java exception; That exception is likely being thrown by
your action class.  Second, in order to acomplish the functionality that it
appears you are describing, ie. submitting a form in a popup window and then
closing the window, you would need to do something like the following:

function setFilter() {
document.PipelineFilterForm.submit();
}


You may also consider using a regular html:submit button and avoid this
javascript above all together (preferable)
and then AFTER the form is submitted, have your action class forward to a
new generic page with some very simple code like



function closeWindow(){
self.close();
}






OR




function closeWindow(){
self.close();
}
closeWindow();




Not sure if this is the best approach, but it ensures that your action class
succeeds before your window closes, so if there is an error you can forward
to a different page while still inside of the popup window.

Just my 2 cents,
Adam Grohs

an org.xml.sax.ErrorHandler was not set?

[Rick Reumann]

I hate to post about a stupid null pointer exception as I'm sure it
will end up being something stupid I'm doing. I'm modifying some of my
code to follow some of David's validation examples. Currently when one
of my forms gets submitted it's supposed to get validated but comes
back with a null pointer exception. Looking at the tomcat output in
the console window shows:

Warning: validation was turned on but an org.xml.sax.ErrorHandler was not
set, which is probably not what is desired.  Parser will use a default

From the Struts "Resources" page:
http://jakarta.apache.org/taglibs/doc/ultradev4-doc/intro.html

You will have to modify your JSPs a little (we code a small scriptlet 
that instantiates the FormBean and put it in some scope - a shell script 
comments it out for production) for it to work with Struts, but it works.

This is a little off topic for this question, but
I just met with an IBM engineer, who was saying
that the latest WebSphere Studio Enterprise Developer
Beta (to be released in a month or so, if I remember
what he said right) will have features specifically
for building Struts applications.

You won't probably be able to build Struts applications
for other platforms with it though.

RE: Struts 1.0.2 checkbox - Error Message: No collection found

You can try using the present tag ex :

 

before actually going into the iterate and checkbox tags. This will check to
see if the collection exists, before executing the logic inside the tag.

This looks like the same problem I posted this AM (subject = logic:iterate

The question is: anybody knows a tool, extension or whatever that actually
work with struts tags ?

So it's easier to build web applications.

I use JBuilder40. It's not very comfortable to build struts applications.

Thanks.

RE: Why Struts - Ryan Norman

[Mike Finn]

Ryan,

1) There may be MVC frameworks available as value-adds to WebSphere,
WebLogic, etc. They may not port from one app server to another. Struts
should run in any JSP/Servlet spec-compliant web container. With proprietary
frameworks, you risk getting precisely what many hope to avoid by
implementing J2EE solutions: vendor lock-in. Plus, with Struts, you have the
(IMHO) benefits of Open Source.

2) We are using Struts with JBoss 3.0b/Tomcat 4.02 integrated.

RE: Why Struts - Ryan Norman

[Joseph Barefoot]

Hi Ryan,

Yes, there are other, propietary frameworks to be used, as well as rules
processing engines, in many of the commercial web servers.

So, why use Struts?

Some of these commercial web servers have very powerful features, but you
pay the price of tying oneself to the web server.  Not just the vendor, but
probably the software version as well.  This makes application maintenance
and migration a tricky endeavor, as you would have to (potentially) re-write
those elements of the application that depend upon the propietary framework.
And, if something doesn't work as expected, you are stuck with it, if you
employ propietary features in your application.


Another reason to use Struts is that it's open-source, which has several
implications:

1.  If you don't like it, then re-write it.  If a feature doesn't exist or
you'd like to improve an existing one, go for it.  Note that this kind of
customization can lead to migration problems as well, however.

2.  Continuous bug-fixes, development, and integration.  I have found that
open-source projects move more rapidly to fix bugs and support new
specifications that commercial products, as the developers who contribute
usually use the software as well.  Therefore, they ARE their own production
test environment, and if there's a bug that annoys you, you can be sure it
annoys them too, and they will move to fix it ASAP.

3.  "It's Quality, not quantity, man."  Open-source developers, in general,
tend to care more about their project's code than commercial developers do.
Why?  Because it is a part of them, not a part of the company they work for.
And if something is a part of who you are, then it tends towards quality
just as you do.  Commercial products may have more bells & whistles, but
that doesn't necessarily make them better.


Of course, it's your choice...I'm sure there are situations that would
warrant using iPlanet (for instance) for its rules engine to rapidly develop
an application, I just don't know what those situations are.

cheers,

Joe Barefoot

RE: Struts 1.0.2 checkbox - Error Message: No collection found

[Yu, Yanhui]

Sorry I forgot that the reset method in the ActionForm looks like this:
==
public void reset(ActionMapping mapping, HttpServletRequest request)
{
cat.debug("ConflictResolutionForm reset");
/*
this.checked = false;
this.linenum = null;
this.field = null; 
this.level = null;
this.currentValue = null;
this.overrideValue = null;
*/

 if(conflicts != null) {
for(int i=0; i< conflicts.size(); i++) {
((ConflictBean) conflicts.get(i)).setChecked(false);
}
}
}
==
Looking forward to hearing any hints, thank you very much,
Yanhui

Hi All,

We are using struts verions 1.0.2 here.  I have a problem using checkbox in
a jsp, getting No collection found error.  Here is my sample code and I
really appreciate if anyone can give me a hand on this.

in ConflictBean class

private String linenum = null;
private String field = null;
private String level = null;
private String currentValue = null;
private String overrideValue = null;
private boolean checked = false;

// all public getters and setters for all the String attributes

public boolean getChecked() {
return checked;
}
public void setChecked(boolean _checked){
checked = _checked;
}
==

in Action class
==
ConflictResolutionForm conFlictForm = new ConflictResolutionForm();
ArrayList conflicts = new ArrayList();
// Fill in the list here

ConflictBean cb = new ConflictBean();
cb.setLinenum("1");
cb.setField("Field 1");
cb.setLevel("Area");
cb.setCurrentValue("012345678");
cb.setOverrideValue("012345678");
conflicts.add(cb);

public void setConflicts(int index, ConflictBean conflict) {
conflicts.set(index,conflict);

Any help would be greatly appreciated.  What I did wrong here? Maybe
multibox is what I need?

Websphere specific problem with template:get tag (flushing..

[Marcelo Caldas]

Hi guys,
I'm trying to deploy my application (developed so far on Oracle 91AS) to WebSphere...

First error I got is a illegal to flush within a custom tag...
I realized that the only struts tag that tries to flush is the template.GetTag. 
Although I'm using a very recent nightly build (2002-03-17), this behavior exists even 
on struts 1.0

Why Struts - Ryan Norman

[Ryan Norman]

Hi,

I am Ryan Norman.

Are there frameworks available in other commercial Java Web Servers like Web Sphere, 
iPlanet, JRun, etc.

. If so why should somebody use struts framework rather than using the Web Server's 
native framework?
. Are there people who are using struts with commercial Java Web Server like Web 
Sphere, iPlanet, JRun, etc.

Thanks in advance

Ryan Norman

Subject: dynamic alteration of multiple entry select box content with
javascript : empty values upon submission
From: Simon Kirk <[EMAIL PROTECTED]>

Hello.

I have an html page with two select boxes configured to allow multiple 
selection in each. The one on the left contains options that are available, 
the one on the right contains options that are selected from those 
available. I've got a javascript method suite that will transfer selected 
options from the box on the left to the box on the right dynamically. I 
know it works with normal html form submission as I've used it many times 
in the past. Now however I'm trying to get it to work with struts.

The first problem I came across was populating the select boxes. Not 
normally a problem, but the form bean I had configured to accept the data 
from the html page complained about various problems. Finally I got this 
nailed. Here's an example of the html:



  Available options
   
  Selected options/td>


  

  

  
  



  
  

  

  
  


(please excuse any shonky indentation :)

I won't paste the javascript functions up here as they're pretty long 
winded.

The top select box gets its options from a bean containing a collection of 
LabelValue beans. The bottom select box gets it options from a collection 
contained in the form bean, which is populated from the database with an 
Action before the form is rendered.

Now, if you click one of the two buttons labelled >> or << the options move 
across into the relative box as expected. But when I submit the form I am 
getting nothing at all in the form bean for either the property 
"allOptions" or "selectedOptions". Nothing at all, not a null value, just 
nothing. This is independant of the type that you set that field to in the 
form bean class you make - struts isn't doing anything clever like turning 
the multiple selection into a Vector on the fly for you.

The selected options should come through as a comma seperated list of IDs.


If anybody has any idea where to go I would be very helpful, as reading 
through the mailing list archive and checking google hasn't really given me 
any useful information. Is there anywhere I can check every value being 
gleaned out of the form by the controller servlet? Printing the query 
string out in the action class that the html page forwards off to doesn't 
help, it's empty too.

Regards,
Simon

Same action called another time after having returned null

[Sergio Ramazzina]

Hi to everybody,
 
I hope someone can clarify me about what is going on with my struts
application.
 
I'm writing an application that gives the users the opportunity to print
some data contained inside the browser page to a pdf file. That pdf file is
produced by an helper class called from a Struts action class. My action
class return null because the action itself produce the file, using the
helper class, and I don't need to forward the control to any page.
 
The pdf file is produced and displayed correctly also with IE but I've
noticed that the action that I call from inside my page to start the pdf
building and displaying is always started two times. It seems like someone,
in the process, calls it another time immediatly after the file has already
been displayed.
 
Below is an excerpt of the log just to clarify
 
==

I've noticed that this behaviour stops if I return a valid forward
reference, and not null, from the action class but I also know that
returning a null from an action class is a permitted behaviour.
 
Is there someone that can help me to clarify my ideas about that?
 
Thanks in advance

Re: Attribute value should be quoted

[Sjaak de Mul]

Hi,

Can't you set the filterType property in the formBean before forwarding to
this page? Then Struts should take care of checking the appropriate radio
button.

Javascript in Struts

[Bhaskar Gopalan]

Hi,

how does Javascript work with struts? I have a 'Filter' form with a couple
of radio, select and text
fields. The only three request parameters are filterSet, filterType and
filterValue.

Example:

   


  
  

Select One
Stage1
Stage2
Stage3
Stage4
Stage5

  


  
  
 

  
  

  


MY QUESTION IS:
Do I have to give the same property "filterValue" instead of "lenderVal" in
the ? If so, suppose the user chooses
the first radio button, but chooses both "Stage3" and enters some dummy text
in  by mistake. Now, will the filterValue be set to Stage3 or the
dummy text? I was initially using javascript (w/o struts) to associate radio
button with the corresponding select/text field. How do I do it now with
struts?

Quick reply appreciated.

Thanks,
Bhaskar

RE: Problem with caching

[Etienne, Ingo (Goetzfried AG)]

Hi,

I had the same problem with IIS and IE5. The solution to this was to set the
cache-control header on the web server, all other attempts were simply
ignored by the browser.

The drawback is that every single page and all images within these pages are
not cached, so you loose the ability to distinguish which pages you don't
want to be cached and which are ok to be cached.

What is your dev environment? IIS + IE5 :)

Hi,

When I try to follow a link to one of My action class. Sometimes, it works 
correctly and sometimes, my browser just take the old copy of the generated 
page it has in cache.

My question is: How can I avoid that ? What do I have to do to be sure my 
browser doesn't set anything in cache ?

I tried to put the following in my jsp pages, without any success:

<%
   response.addHeader("pragma","no-cache"); // http v1.0
   response.addHeader("cache-control","no-cache"); // http v1.1
%>

Could anybody point me to the right way to achieve that ?

Thanks in advance.

For all actions, you could configure the ActionServlet in web.xml, like 
this:

RE: checking action name

[Steve Hupert]

In the perform method of my action class, I have stored the path attribute
of the forward being returned from the mapping object as an attribute in the
request.  I can then access the path from JSP pages to determine what lead
me to the JSP page.

For example in the perform method:
request.setAttribute("path", mapping.findForward("success").getPath());

Then in the JSP page:
 will give me the path that resulted in this JSP
being called.

If anyone has better ideas on how to handle this, I would like to hear about
them as well.

RE: Installation on OS-390 and Websphere 3.5.3: Was 503Error- Now What struts.jar should I use.

[Steven Banks]

Roger.   Thanks for the response.   Before trying the upgrade, I am going to try 
getting it to work on 3.5.3 "just call me stubborn".  There is a set of notes from 
someone who has it working on this user group.   The latest I have tried was changing 
a WAS start-up parameter "appserver.compliance.mode=true".  The result was the the 
servlet does not load at all.  It could not find the config file.  I have since 
discovered that one result of the parameter change  is that the location of the 
struts-config.xml file has to be moved as the following code from the Action Servlets 
initMapping routine no longer worked.

When  appserver.compliance.mode=false  "the default value"

 InputStream input = getServletContext().getResourceAsStream(config); 

found the xml file in the following directory:   
   u/mywebs/dev/train/WEB-INF/classes/WEB-INF/struts-config.xml


When  appserver.compliance.mode=true,   the xml file had to be moved to
 /u/mywebs/dev/train/web/WEB-INF/struts-config.xml


It would be nice if the main struts code would return 
getServletContext().getRealPath(config));   when it cannot find the config file, this 
would solve a lot of problems like this very quickly.  

Once I moved the file to this new location, the servlet starts OK, but returns the 
http 503 error again as soon as I try to access any file in the web application.

I am going to put a call in to IBM tech support to see if they can help, but any other 
help here would be appreciated.

Below the dotted line is a message that was posted on IBM newsgroup for
WebSphere AS400 and basically Struts will not work with Websphere 3.5.3
on AS400. You must upgrade to 3.5.4.  Perhaps it's the same for
websphere on OS-390?

Also, check this link for a version of struts-jar that will work with

Good News:  Yes, it will work.
Bad News: You may have to jump through a few hoops, depending on just
what
it is you intend to do in the application, how you intend to deploy, and
what your AS400 configuration looks like.

3.5.5 hasn't really been out all that long, and when you consider that
anything like this for the 400 always comes poking along several weeks
or
months after the other platforms my guess would be that higher won't be
an
option for a while.

The way it has shaken out for me is that struts apps deploy fine on
versions
3.5.3, 3.5.4, and 3.5.5 for Windows.  I did do the documented hacks for
the
struts source and the parser.jar that are out on the Apache site.  This
may
not be necessary in version 3.5.5, but unfortunately I haven't had
adequate
time to investigate it.  If it isn't fixed, dock IBM several points for
not
walking it the way they talk it with regard to open source.  But don't
assume if it works on Windows it will work on the 400 - more on that
later.

In addition, I did have to change struts-config.xml and web.xml to use
system rather than public dtd's.  This was not necessary on my Windows
desktop, but when I deployed to the 400 I got numerous errors when the
webapp loaded.  Changing the dtd ref did the trick.  If your machine is
behind a firewall with no internet access you'll also have to make sure
the
dtd can be found, so you may need to specify an internal uri.  Don't
worry,
the system log will let you know right away if it doesn't like what you
picked.

I used the Struts connection pooling option because I used Tomcat as my
development server, and because I want to build in some monitoring that
is
currently not available in WSE for the 400.  I developed on Windows
using
the AS400 toolbox drivers, and switched over to the native DB2 drivers
when
moving up(Don't ask me why).  I ran into some issues there where I was
not
able to update certain files using SQL (support posts seem to point to
issues with non-journaled files), and switching back to the 400 drivers
cleared it up.  Not sure why, since connections using the WS connection
pool
and these same drivers seem to have no issues.

The big news is that while I got my apps to deploy to a 3.5.4
installation
on the 400, no amount of installing, finessing or tears/breastbeating
could
get them to run on 3.5.3.  Even though they ran alright on the same
number
release on Windows (and Linux for that matter ).  So my hunch is that as
long as you are on 3.5.4 on up you are OK.  But as to the line that if
it
runs on one it should run on the other platform versions of the same
number
release?  Well, I never say never, and I will always concede the
possibility
that it could be issues on my end somewhere.  But let's just think for a
moment on IBM's overall consistency in this area and in overall quality
of
delivered software product(my own view, there are some great successes
and
equally great failures), and it isn't 

can TILES use existing jsp files ?

[Melissa . Manoogian]

My current project is using Struts 1.0 and I already implemented about 20%
of my .jsp files,
without giving too much thought to the navigation.
Now I want to use tiles to implement the sidebar menus for navigation.
I am hoping this does not mean I will have to re-implement  those .jsp
files, i.e.
I imagine I could simply put each of my jsp files in the
place where we put body.jsp. However I am getting an error message because
each of my jsp
pages is using this tag "bean:message key=index.title".

In my struts-config.xml I added  this tag for message-resource:
  message-resource parameter
="org.apache.struts.example.tiles.dev1-1.ApplicationResources" null="false"

I tried both: tiles for struts 1.0 and tiles for struts 1.1 with the same
error message (see
bellow).
Searching  the mail-archive I found the same error but the scenario was
different - that tiles user *was
not using* the ApplicationResource, but was forced to specify it anyways.
In my case *I am
using* the ApplicationResource but the servlet cannot find it when I am
using tiles. It finds it ok
if I am not using tiles, i.e. if I am using just struts 1.0.

logic:iterate and "no collection found"

[Mike Finn]

Hi 
All,
 
I have a 
form with an array of subforms on it, like so:
 
class 
BigForm extends ActionForm
{
  SubForm subFormX[];
 
  public SubForm[] getSubFormX() { return 
subFormX; }
  public void setSubFormX(SubForm[] 
newSubFormX) { this.subFormX = newSubFormX; }
 // 
other attributes...
}
 
When this 
has no data in it, and I use iterator on it, like so: 
(assume 
"TheBigForm" is declared w/ type BigForm in 
struts-config.xml)
 

   

 
I get "No 
Collection found" ServletException.  The BigForm is in request scope, and 
in fact if I force-feed it with data, everything works OK. I also wrapped the 
iterate block with logic:present to no avail:

...

 
Also, I 
initialized the array to new SubFormX[0] - again, no luck.
 
What is 
the correct way to handle this situation - where you have a sub or child form 
with an empty array?
 
TIA,
Mike

Re: Need example on using roles in struts-tiles

[Ted Husted]

When container-based authentification is being used, you can specify the
secuirty role for a tile. If the user is not in the specified role, then
the attribute value is not set. This allows you to specify a tile for
each security role, and let the framework select the appropriate one for
the current user.




If the put command is being used in an insert tag, the role is checked
immediately.  If the put command is being used within a definition tag,
the role is checked when the Tile context is initialized 

Jakarta taglibs also has a handy IsUserInRole tag in the request taglib.

Re: Using MessageTag for handling plural/singular

[Ted Husted]

In general, the answer to most questions like this is to do the work in
the Action, and then place the result in a bean for easy display. You
can obtain a reference to the message resources in the Action, 

MessageResources resource = servlet.getResources();

and then use the Java text-handling classes 

http://java.sun.com/docs/books/tutorial/i18n/format/index.html

like you would in any conventional Java program. 

The outcome can then be passed to the page in a simple JavaBean and
output with bean:write. The strength of Struts is that the Action class
provides a gateway to the business tier and lets us write Java programs
like Java programs.

Re: Form Beans - Vector

[Ted Husted]

Generally, specifying the type seems to help. 

.. type="java.util.Vector" ...

I don't use Vectors myself, since the synchronized aspect is not useful
in the kind of applications I tend to work on, but using them with the
iterate tags does seem to generate a lot of messages. 

If you continue to have problems, and if it's possible to use another
collection class, like ArrayList, I'd do that. If not, I'd add a helper
method that returned the Vector as an array.

combination of and getMessage("sometag") in JSP: how

[Lukas Österreicher]

Hi.

I've got some i18n jsp pages which work so far by using commands like:

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bn"%>
<%  setLocale(session, request); %>
and


The problem is that now I've got some java code within the jsp
where I need to include some internationalisation - which
obviously won't work with 

Hope you can help me!

Cheers!

Re: Can Dreamweaver and Struts work together

[Jon Ferguson]

Hi,

Only as a trial... However I seem to remember reading that due to Ultra-Dev formatting 
constraints
you need to START with UltraDev.. eg. DO not attempt to build a file in some other 
editor first.

Hope this helps,

Jon

Is it possible to find in the JSP what action mapping has lead us there? Is
there a parameter in the request?

form-bean problem

[Viet Kevin]

Hello all I'm facing a problem and I want to get advices from you

I have three bean class that are extending from the same base class
the base class is declared as abstract

Now I want to create three action forms for validating the informations corresponding
to each of these beans.

For this I have created a base abstract action form and extended it to implement
the action forms corresponding to the beans.
In the abstract form I validate the properties of the abstract bean class and
in the three beans implentations I validate (calling the super.validate) all the
properties

The problem I have to deal with is that I don't want to declare in my 
struts-action.xml file
the three concrete form bean. I want to declare only one action form with the type of 
the abstract class
with one name. In one of my action I will instantiate the right concrete form bean put 
it in the session scope
(core struts wont have to create it again) with the name declared in the config file, 
then at validation 
time the struts core will get the action form bean from the session and validate the 
right way.

I have tested that but the problem is the following :
struts finds the bean in the session scope, then it retrieves the form-bean declaration
from the struts-config file and then test if the name of the class declared in the 
form-bean tag
is equal to the name of the class retrieved from the session. 
These names of course are different because one is the name of the abstract action 
form class and the other one of the name 
of the three concrete action form

Is there an another way to do or maybe I have to patch the struts core for making it 
search 
into the class hierarchy other than on the name of the form-bean class?

In TC 4 the verification of the web.xml syntaxe is more restricting.

you should verify that you correctly declare your web.xml as in the dtd :





The order of the elements is important.

"Dependent Drop-Down Combo Box Lists
In many situations, you will have two combo boxes, with the contents of the
second
dependent on the value selected in the first. That is, each item in the
first combo box is
associated with a list. To handle this, you need for the first combo box to
do a submit
when it changes, so that you have a chance to update the second. You do this
with:





In this example, the property "value", of the beans in orglist are
orgIds and the "labelProperty" property is the name to display. When
you are in your action class the first time, the orgId string property
of your form bean will be null or blank. In subsequent submissions the
orgId property of your form bean will contain a valid orgId, so that
you can look up the list associated with that value, and thus populate
the second drop-down combo box propery.
