Please respond to Struts Users Mailing List I think this issue is very well explained by Ted in his book Struts In Action.. As he says,Forms sghould be just treated as carriers of data till the data is validated and hold the data till in case same is required to be returned to the user. So we should not waste too much time to design form classes but add attributes as and when required. SO depending on u r system,U have to decide. But what i have found works best is have a base form for all Aplication which has common properties (Like UserName,Company id etct etc which is required for each user..)And then extend forms per functionality(Like one super class form for 4 or 5 OrderFunctions ). And also as u said, i also had to add common attributes at the module level.But this works best.

Hello, Not sure if this deserves another thread or if I can attach it to this one. I'm new to mailing lists so please be kind. : ) I'm working on a struts project now and going back and forth on whether to just have one form for the whole system or have many forms. In our case we put the common fields in a base form and created other forms to extend that one. Each of those forms correspond to a specific section in the system. The problem we're running into now is that we're finding more and more common items and having to move them into the base form. Which lead me to think about just having one form and not bothering with the others. Comments? Taylor Cowan t.cowan@charter.To: Struts Users Mailing List [EMAIL PROTECTED] net cc: (bcc: David Z. Pantich/OE/FirstEnergy) Subject: Opionions: fine or course grained actions 02/07/2003 09:19 AM Please respond to Struts Users Mailing List I wanted to see what others in the struts community think about Action granularity. I've coded apps that are -extremely- fine grained, having one Action per user event, like createPreferencesAction, deletePreferencesAction, update...etc. The fine grained approach yields more than one action per screen, and contention for the struts config file during development. In the middle are apps that basically have one action per screen that handles all the button clicks with a switch if/else block. That's the moderate approach. The last style is -extremely- coarse grained in that there might only be one action for the entire app. Coarse grained has worked best for XML/XSLT type work flows and in some other situations. What do you think about Action granularity, should it be very fine and thus more HTTP like in nature, or more coarse grained having fewer URL's?

select multiple=false == select multiple=true
The documentation for html:select indicates that if the multiple attribute is specified with ANY non-null value, it will be rendered as a multiple select. However, it would be much more intuitive if this accepted a boolean value like, for instance, the disabled attribute of html:option. I understand that leaving off the attribute will render a single select, but if the value of multiple is coming from a bean, and since it makes sense that this is a boolean value, it would follow that the multiple attribute would understand a boolean value. I can have my bean return a String instead of a boolean, and default that String to null, but it still seems as though this attribute could be more developer-friendly. Am I missing some logical reason behind the behavior of this attribute? Am I the only one who thinks this is counter-intuitive? Would it make sense to allow boolean values for this attribute in future releases? Thanks, Justin

Thank you so much for the reply. We are still in construction and completed 3 of the 4 phases of our project. System testing on phases 1to 3 begin soon.

RE: Is anyone using tomcat 4.1.18 with nested tags?
Sri Jeff, I have seen this inconsistent behavior and can duplicate it fairly painlessly. I found when testing for bug 15799 that in some cases the bean name property for a nested write was null. Going up the tree I couldn't find any unmatched resets for the bean name where a reset changed the name to null but I didn't look at reused tags a potential source for the problem. I also don't understand why the nested tags like NestedWrite don't implement a reset. It is likely that it is just fine but it also seems possible that there should be a reset to originalProperty and isNesting in the NestedWrite tag. I haven't spent time researching this either.

RE: Nested Tags Problem .... Urgent
The code you have presented isn't very clear. Your Action, for example seems to
declare the controlVO1 reference twice -- won't compile.
Are you trying to say that you have a list of objects within the ActionForm? Is it
being placed in the session/request under the key formList -- 'cos that's how you
are trying to retrieve it in the JSP. Why do you have the getAttribute(...) stuff?
Also, what version of Struts are you using?

How to access ApplicationProperties elements???

I need to be able to get to some of the elements within this file for generating messages to be displayed in my view, but cant find any examples on how to do this. TIA Pete Serafin
Re: select multiple=false == select multiple=true
You are right, but backwards compatibility problems could be *nearly* eliminated depending on how it's implemented. If null and false were the only values that would not render a multiple select, then it would work in all cases except for those where people are using multiple=false to render a multiple select box. If somebody is shortsighted enough to do that, then they deserve to have the implementation change. ;) Justin - Original Message - From: David Graham [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, February 11, 2003 11:38 AM Subject: Re: select multiple=false == select multiple=true Your point does make sense but changing the behavior would introduce backwards compatibility problems.

Now I am getting a sharing violation whenever I try to save an edited JSP file after testing the application. The file seems to be locked by Tomcat. After restarting tomcat everything works fine as long as I do not test the application in my browser. My environment is Tomcat 4.0.3 on Win2K with Struts 1.1b3. Does anybody know of a solution? It is very annoying to restart tomcat for each small change in a JSP. Tomcat 4.0.3 did indeed leave files open on occasion, which shows up as sharing violations on Windows. Upgrade to 4.1.18 to avoid this. However, switching Struts versions would not have done anything to trigger the problem -- Struts itself does not open the JSP pages.

LookupDispatchAction Question
I am new to Struts and am trying to use the LookupDispatchAction class to display a
page for the first time (i.e. the user is being navigated to this page from another
page).
I have everything setup fine in my struts_config.xml and Struts attempts to display my
page, but was giving the following error:
Request[/lookup] does not contain handler parameter named submit
After researching on the archives, I realized that this message is due to the fact
that the user has not yet clicked any of the submit button on this page (the page
hasn't even been displayed yet). The suggestion on the archive is to implement
something similar to the following in the Action class which extends
LookupDispatchAction:
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse)
throws Exception
{
if (httpServletRequest.getParameter(actionMapping.getParameter()) == null)
{
return defaultMethod();
}
else
{
return super.execute(actionMapping, actionForm, httpServletRequest,
httpServletResponse);
}
}
My question is what do I return from defaultMethod? I have to return an
ActionForward but I don't want to forward the user anywhere -- I want to display the
page. How do I do this? I guess I could have 2 pages and 2 actions -- one to display
the page initially and one to process the page upon submit -- but that is ugly and I
hope not the only solution.

I would suggest you read up on the usage of the LookupDispatchAction again.
It was not designed to to be used in the way you are trying to use them.
Take a look at this site http://husted.com/struts/index.html. It has some
good suggestions on the correct usage of the action classes that come with
struts.

Subject: LookupDispatchAction Question
I am new to Struts and am trying to use the LookupDispatchAction class to
display a page for the first time (i.e. the user is being navigated to this
page from another page).
I have everything setup fine in my struts_config.xml and Struts attempts to
display my page, but was giving the following error:
Request[/lookup] does not contain handler parameter named submit
After researching on the archives, I realized that this message is due to
the fact that the user has not yet clicked any of the submit button on
this page (the page hasn't even been displayed yet). The suggestion on the
archive is to implement something similar to the following in the Action
class which extends LookupDispatchAction:
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse)
throws Exception
{
if (httpServletRequest.getParameter(actionMapping.getParameter()) == null)
{
return defaultMethod();
}
else
{
return super.execute(actionMapping, actionForm, httpServletRequest,
httpServletResponse);
}
}
My question is what do I return from defaultMethod? I have to return an
ActionForward but I don't want to forward the user anywhere -- I want to
display the page. How do I do this? I guess I could have 2 pages and 2
actions -- one to display the page initially and one to process the page
upon submit -- but that is ugly and I hope not the only solution.

RE: LookupDispatchAction Question
U, I'm not sure from your message what you are doing. It sounds like you
are forwarding to a page that contains a form and requires some
initialization.
In that case you would use the [parameterName]= to call the unspecified
method.
In your LookupDispatchAction there is an unspecified method that is called
when you do not specify a value for your paramter. So you just need to
specify an unspecified method in your LookupDispatch action that will
contain all the initialization logic calls that are needed. That would allow
you to use the same page for different dispatch methods.

RE: LookupDispatchAction Question
After the user logs on they are supposed to go to a lookup page. This page will have
no data on it when it is first displayed. This page, which is a JSP of course, will
have a form and more than 1 submit button.
The problem is that the page can't even be displayed because when Struts calls my
Action class (which extends LookupDispatchAction), there is no value for the submit
button. That is, Struts doesn't know which of my methods to invoke and throws an
exception (the error message from my first email). This is because the user hasn't
clicked any of the submit buttons yet -- they haven't even seen the page.
How do I get the page to display initially?

RE: LookupDispatchAction Question
simple...
in your execute method check to see if the mapping.getParameter is null.
If it is null then have it call a method that performs some initialization
(if needed) and returns an ActionForward to your jsp page.
If you want code... I have done this many times.

AW: LookupDispatchAction Question
also if your parameter is not null then call the
super.execute(mapping,form,request,response) so that the lookup does it's
work as normal. The key is to override the execute method of the
LookupDispatch and pass control to it only if the paramter exists in the
query/request.

in your execute method check to see if the mapping.getParameter is null.
If it is null then have it call a method that performs some initialization
(if needed) and returns an ActionForward to your jsp page.
If you want code... I have done this many times.

After the user logs on they are supposed to go to a lookup page. This page

My question is what do I return from defaultMethod? I have to return an

RE: need Help, I have been struggling for days. (collectionsandhtml:select)
Thanks for your reply, but I guess I forgot to mention that my drop
menus work and the info in the collection shows up, but on submit it
says that the bean can not be found. I figure its pretty strange since
the info is taken from the same bean on form creation. Got any more
ideas, I'd love to hear them.
Thanks for your suggestion.

I am new to struts but when I used the select with options tag I
created 2 equal size vectors (labels, values)the jsp was
td
html:select name=incidentForm property=selectedUnsafe
html:options name=incidentForm property=unsafeValues
labelName=incidentForm
labelProperty=unsafeLabels /
/html:select/TD
or, in another case I used the iterate tag to create a list:
logic:iterate id=test

tr
tdhtml:submit property=removeUnsafe value=Remove //td
tdbean:write name=test property=desc filter=false//td

I am trying to do something I have done many times before
I have a collection of objects which I want to use in a drop down menu
for the user.
I have a vector that contains (int ids,Object )
In the object bean I have methods that get/set the values, for example
public String getCriteriaName(){...}
In my jsp I have several text fields and I am able to get the values
of
them in my action bean. This criteria is the only value I am having
trouble with. I get a Cannot find bean under name criteriaList. I
have
done this before with vectors of similar structure and I am really
confused.
html:select property=criteriaName
html:options
collection=criteriaList
property=id
labelProperty=criteriaName/
/html:select
In my action form bean I make objects and put them in a vector then I
request.setAttribute/session.setAttribute depending on scope.
All I want to do is to get the string value back from what the user
selects.
If anybody can Help, it would be great.
Thanks in Advance.

RE: LookupDispatchAction Question
Okay this is one way of doing this:
Your login action in this case should not be a LookupDispatchAction. It
should be a sub-class of the struts Action class. LookupDispatchAction has
another intended usage.
When your user is authenticated (from the login action), you will forward to
the jsp that is suppose to contain all the submit buttons. Assuming
everything else is configured properly, your JSP should then display
properly.

In that case you would use the [parameterName]= to call the unspecified

In your LookupDispatchAction there is an unspecified method that is called
when you do not specify a value for your paramter. So you just need to
specify an unspecified method in your LookupDispatch action that will
contain all the initialization logic calls that are needed. That would allow
you to use the same page for different dispatch methods.

My question is what do I return from defaultMethod? I have to return an
ActionForward but I don't want to forward the user anywhere -- I want to
display the page. How do I do this? I guess I could have 2 pages and 2
actions -- one to display the page initially and one to process the page
upon submit -- but that is ugly and I hope not the only solution.

Re: Strange Validator Problem
It was 1.4.1_01, but I have switched to 1.4.0_03-b04 and the problem is still present. I appreciate your help; do you have any other suggestion? Thanks!

When I execute this, I get the logon.jsp page successfully displayed, but if I leave the fields blank and submit, no errors occur, but a blank white display shows up in the browser. Now the strange part, if I change validate=false, check for non-existent password or userid in the Action, and use errors.add() to add the appropriate errors; this time when I submit with the fields blank, I get the form re-displayed with errors. The 'input' key remains the same between both versions. If I set up a log4.properties file with the level set to DEBUG, I can see that the resource keys for the error messages are being loaded, and I get a message saying that the validation failed -- so I know the validator is being called. The last message I get tells me: Validation failed, returning to '/logon/logon.jsp'. But all I get after that is a blank white page, yet the '/logon/logon.jsp' is the correct path and works when validate='false'. Any ideas?

[OT] - ServletContextListener
Does anybody know if the container should be setting the contextClassLoader on the current thread when it loads the various listeners configured in web.xml? The particular behavior we're seeing is that the contextClassLoader for the thread launching our listeners (both context and session) is not a weblogic specific loader (whereas other classloaders are). This causes a problem for us because we have our own commons log factory that we use, but because we specify this in a property file in our web app, the listeners are using a contextClassLoader that doesn't have access to the web app, which causes commons to default to using simpleLog or whatever the default is. I know a lot of you are familiar with the Servlet spec (or wrote it in some cases ;)Can anybody tell me if this might be a bug in weblogic or if it is the expected behavior (or best case, point me to some documentation that will explain the way this should work in a web container) Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

throws Exception
{
if (httpServletRequest.getParameter(actionMapping.getParameter()) == null)

Have you verified that your struts-config file is correct. In particular, does the

In my action form bean I make objects and put them in a vector then I

If anybody can Help, it would be great.

But there is nothing that I can find that tells me how to initially display
a page that will subsequently use a dispatch action. In fact, I can't figure
out how to do it in Struts at all without either having a plain .html page
as the inital page or having 2 .jsp pages. Niether solution is good.

Scott,
Have you verified that your struts-config file is correct. In
particular, does the action associated with the submit have the correct
form bean name and also that the scope is the same as the scope used in
the action which displayed the form.

Thanks for your reply, but I guess I forgot to mention that my drop
menus work and the info in the collection shows up, but on submit it
says that the bean can not be found. I figure its pretty strange
since
the info is taken from the same bean on form creation. Got any more

I am new to struts but when I used the select with options tag I
created 2 equal size vectors (labels, values)the jsp was
td
html:select name=incidentForm property=selectedUnsafe
html:options name=incidentForm property=unsafeValues
labelName=incidentForm
labelProperty=unsafeLabels /
/html:select/TD
or, in another case I used the iterate tag to create a list:
logic:iterate id=test
name=incidentForm
property=unsafe
type=GeneralForm
tr
tdhtml:submit property=removeUnsafe value=Remove //td
tdbean:write name=test property=desc

tdhtml:hidden name=test property=id //td

I am trying to do something I have done many times before
I have a collection of objects which I want to use in a drop down
menu
for the user.
I have a vector that contains (int ids,Object )
In the object bean I have methods that get/set the values, for
example
public String getCriteriaName(){...}
In my jsp I have several text fields and I am able to get the values
of
them in my action bean. This criteria is the only value I am having
trouble with. I get a Cannot find bean under name criteriaList. I
have
done this before with vectors of similar structure and I am really
confused.
html:select property=criteriaName
html:options
collection=criteriaList
property=id
labelProperty=criteriaName/
/html:select
In my action form bean I make objects and put them in a vector then
I
request.setAttribute/session.setAttribute depending on scope.
All I want to do is to get the string value back from what the user
selects.
If anybody can Help, it would be great.
Thanks in Advance.

After the user logs on they are supposed to go to a lookup page. This page
will have no data on it when it is first displayed. This page, which is a
JSP of course, will have a form and more than 1 submit button.
The problem is that the page can't even be displayed because when Struts
calls my Action class (which extends LookupDispatchAction), there is no
value for the submit button. That is, Struts doesn't know which of my
methods to invoke and throws an exception (the error message from my first
email). This is because the user hasn't clicked any of the submit buttons
yet -- they haven't even seen the page.
How do I get the page to display initially?

After researching on the archives, I realized that this message is due to

ActionForm actionForm,
HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse)
throws Exception
{
if (httpServletRequest.getParameter(actionMapping.getParameter()) == null)

else
{

Adding a new object to a collection in an actionform

I know I can create an empty object just by doing this:
nested:submit onclick=addmonkey.do
property=addBananaForMonkey
value=Add New Banana For Monkey/
But how do I go about creating a new banana with initialized properties
that come from a nwe form on another page. Is it possible?
I need the new form because I want the user to enter the details for
the banana BEFORE it is created as blank in the actionform.
It would be ideal if I could enter these new details in a popup window
of some sort but how do I go about doing this,

The particular behavior we're seeing is that the contextClassLoader for the thread launching our listeners (both context and session) is not a weblogic specific loader (whereas other classloaders are). This causes a problem for us because we have our own commons log factory that we use, but because we specify this in a property file in our web app, the listeners are using a contextClassLoader that doesn't have access to the web app, which causes commons to default to using simpleLog or whatever the default is. Yes, listeners should be configured with the thread context class loader set to the webapp's class loader. Note that the specific requirement to provide a per-thread context class loader at all is in the J2EE Platform Spec (Section J2EE.6.2.4.8), not in the servlet spec. Although there is no specific mention of listeners (as opposed to any other class), it makes no sense to make it available for some components (servlets and filters) and not others. I know a lot of you are familiar with the Servlet spec (or wrote it in some cases ;)Can anybody tell me if this might be a bug in weblogic or if it is the expected behavior (or best case, point me to some documentation that will explain the way this should work in a web container) I would report it a WebLogic bug.

RE: LookupDispatchAction Question
Okay from what I got:
Login - Lookup
Login is an Action.
Lookup is a LookupDispatchAction.
The problem is that it is forwarding to ur LookupDispatchAction class and
not to you lookup page.
If this is wrong then stop reading ur wasting ur time and I've already
wasted mine.
So I'm assuming that your Login action class has an execute method that
looks like:
execute()
{
//handle login
blah...
return mapping.findForward(success);
}
like most standard struts applications and that ur success is to an action
In addition your forward is defined as such:
forward name=success
contextRelative=true
path=/myLookupAction.do
redirect=true/
which means that it goes to your Lookup dispatch action.
Fine. At this point you have several options one of which is the following:
replace path=/myLookupAction.do (or whatever you have)
with path=/myLookupPage.jsp (to go directly to ur jsp)

Accessing Properties of DynaValidatorForm from a JSP
I'm a realtive Struts newbie, and am now retrofitting my first project
with Validator and dynamic action forms. On one page, I need to compare
a property from the action form object with a value in another bean. I
had been using JSTL like this:
c:if test=${category.id == editArticleForm.category}
But this fails now that I've converted to a DynaActionForm. It says
that it can't find the property. I assume this is because the
properties are exposed via a get() method rather than getCategory like
it was in my manually created ActionForm.
What's the best way to do this comparison?

I had been using JSTL like this:

But this fails now that I've converted to a DynaActionForm. It says
that it can't find the property. I assume this is because the

RES: [OT] Resin 2.1.6 doesn't like resource-env-ref
Hi Sri, I'm having the same trouble here. Seems to me that it's a resin problem. I have tried to search some help to fix this problem at www.caucho.com, but have found nothing until now. You are right about web-app_2_3.dtd, but I have a web-app_2_2.dtd copy that do not have any reference to a 'resource-env-ref'. I think that resin 2.1.6 use 2_2 to validate web.xml.

Indexed properties and form
Hi,
I have a JSP page that outputs data using a Collection
using the following section
logic:iterate id=lifeBenefit name=lifeBenefits
type=com.quote.dao.BenefitLineItem
indexId=classNum
tr valign=middle class=bg2
td height=28 bgcolor=#FF
table border=0 cellspacing=0 cellpadding=0
tr
td
html:checkbox name=lifeBenefit
property=benClsTtl indexed=true/html:checkbox
/td
td class=formtext %=i %/td
% i++; %
/tr
/table
/td
/tr
The above JSP is converted into the following HTML
code
table border=0 cellspacing=0 cellpadding=0
tr
td
input type=text name=lifeBenefit[0].benClsTtl
size=17 value=some EMPLOYEES
/td
/tr
I am having a problem writing the corresponding
ActionForm,
the problem is how do I declare the variables to
capture the values entered by the user
I have attempted to write it and here is what I came
up with
public class GotoStep4Form extends ValidatorForm
implements Serializable {
private ArrayList records = null;
private BenefitLineItem [] lifeBenefits;
private String [] benClsTtl;
public ActionErrors validate(
ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = super.validate(mapping,
request);
if(errors == null) errors = new ActionErrors();
if (!errors.empty() ) {
HttpSession session = request.getSession();
}
return errors;
}
public BenefitLineItem getLifeBenefit(int index) {
while(index =records.size() ){
this.records.add(new
BenefitLineItem());
}
return (BenefitLineItem) records.get(index);
}
/**
* Gets the benClsTtl
* @return Returns a String[]
*/
public String[] getBenClsTtl() {
return benClsTtl;
}
/**
* Sets the benClsTtl
* @param benClsTtl The benClsTtl to set
*/
public void setBenClsTtl(String[] benClsTtl) {
this.benClsTtl = benClsTtl;
}
/**
* Sets the lifeBenefit
* @param lifeBenefit The lifeBenefit to set
*/
public void setLifeBenefit(int index, BenefitLineItem
lifeBenefit) {
this.lifeBenefits[index] = lifeBenefit;
}
public BenefitLineItem[] getLifeBenefits() {
return lifeBenefits;
}
public void setLifeBenefits( BenefitLineItem[] v) {
lifeBenefits = v;
}
}
The above gives me an error :

The particular behavior we're seeing is that the contextClassLoader for the thread launching our listeners (both context and session) is not a weblogic specific loader (whereas other classloaders are). This causes a problem for us because we have our own commons log factory that we use, but because we specify this in a property file in our web app, the listeners are using a contextClassLoader that doesn't have access to the web app, which causes commons to default to using simpleLog or whatever the default is. Yes, listeners should be configured with the thread context class loader set to the webapp's class loader. Note that the specific requirement to provide a per-thread context class loader at all is in the J2EE Platform Spec (Section J2EE.6.2.4.8), not in the servlet spec. Although there is no specific mention of listeners (as opposed to any other class), it makes no sense to make it available for some components (servlets and filters) and not others. I know a lot of you are familiar with the Servlet spec (or wrote it in some cases ;)Can anybody tell me if this might be a bug in weblogic or if it is the expected behavior (or best case, point me to some documentation that will explain the way this should work in a web container) I would report it a WebLogic bug.

Is there a logical reason you can think of to explain why BEA did it this way? This still seems like a bug to me.. Well, from a container developer's perspective, the code that invokes a ServletContextListener is in a completely different place than the code that invokes a servlet. So, it's really easy to visualize that the person who added a Thread.getCurrentThread().setContextClassLoader() in one place forgot to add it in the other ... Bottom line -- it's much more likely that this was an oversight than that it was a deliberate design choice. That has certainly the case for Tomcat in a few corner cases like this.

The particular behavior we're seeing is that the contextClassLoader for the thread launching our listeners (both context and session) is not a weblogic specific loader (whereas other classloaders are). This causes a problem for us because we have our own commons log factory that we use, but because we specify this in a property file in our web app, the listeners are using a contextClassLoader that doesn't have access to the web app, which causes commons to default to using simpleLog or whatever the default is. Yes, listeners should be configured with the thread context class loader set to the webapp's class loader. Note that the specific requirement to provide a per-thread context class loader at all is in the J2EE Platform Spec (Section J2EE.6.2.4.8), not in the servlet spec. Although there is no specific mention of listeners (as opposed to any other class), it makes no sense to make it available for some components (servlets and filters) and not others. I know a lot of you are familiar with the Servlet spec (or wrote it in some cases ;)Can anybody tell me if this might be a bug in weblogic or if it is the expected behavior (or best case, point me to some documentation that will explain the way this should work in a web container) I would report it a WebLogic bug. ISTR a similar sounding bug in Tomcat 4.1.x as well, but *think* that that's been fixed.

You are right about web-app_2_3.dtd, but I have a web-app_2_2.dtd copy that do not have any reference to a 'resource-env-ref'. I think that resin 2.1.6 use 2_2 to validate web.xml. The servlet 2.3 specification file (a pdf file) shows both versions (2.2 and 2.3). If you look at version 2.2 there is no reference to 'resource-env-ref' too. I have no solution to fix this yet. If you find a solution, let me to know. The resource-env-ref element was indeed added in Servlet 2.3, so any 2.2 container isn't going to recognize it. You don't say what kind of a resource you are trying to create a reference for, but can't you use a resource-ref instead? That is available in 2.2 as well as 2.3.

RE: Exception loading sessions from persistent storage
It looks like there is a non-Serializable object on your session.

DynaForm and ActionForm subclassing
Hi, For certain actions I subclass my own version of the ActionForm. So I implement MyActionForm. This is the base of a number of my forms. (for example, I have an MultilanguageForm that handles forms which stores multilanguage data). How can I do this with DynaForms ? Do I have to subclass DynaForm and add just the properties as I did in MyActionForm ? Can a Dynaform extend another one ? If I understood well, in a DynaForm, the properties are stored in a Map ? So I am not sure if the properties will work ... Any help or link to docs is helpfull !!!

Re: ResultsetDyna class
Craig, I, actually, require a third semantic (that I'm willing to implement myself, btw): I want, like in the a ResultSetDynaClass, a structure that does not copy the elements, from which I can get an Iterator. Now, once I getNext() from the Iterator, I want to get a copy of the object, so that I can later use it, even after exhauting the ResultSet. This is a kind of a lazy loading. BTW, the advance () method is what I would use if I want to advance, but not have the copy generated... What do you think? Do you think I could make create a constructor for ResultSetDynaClass/ResultSetIterator that receives a boolean that specifies if I want copies of elements rather than references? Zorzella Craig R.

RE: still wondering Re: Where to repopulate dynamic lists ?
What? You're going over my head? Fine. Be that way. I'm now going to charge you double for my free advice and unsolicited opinion :) [snip-and-rearrange] Yes, actually I never did put the list into the form bean but had initially put the list in request scope. Now we've come full circle:) We're back to the beginning where it seems the choices seem to come down to: 1) putting the list into session scope (the list will reset when the user hits the setUpAction on another request to do this type of action). or 2) put the list into request scope and repopulate this list when reset is called. Now I'm confused ... if you don't have the property in the form, then what kind of reset() are we talking about? If you're suggesting having ActionForm.reset() do anything besides release its own resources, then I'm agin' it. My sneakiest suggestion was to presume that there will continue to be only one instance of your form bean instantiated and you could get away with not releasing the list reference in the reset() method so it would still be there when the form validation failed. If your objection is having the reference in the session scope after the action chain is finished, then have action #2 remove it [via pageContext.removeAttribute()]. If other people have objections, then let them stand up and state them. [snip-and-rearrange] To recap I'm wondering what is the best practice for repopulating a dynamic list that a user would need on a form. For example possibly it's a form where a user has to select from a list ofOrder Numbers(which could frequently change and could be based on the user logged in). The way I currently tackle this is in the setUpForm type of action a business object is called which returns to me this list and puts the list into request scope to be used on the form. The problem is when the user submits the form and validation returns false. Somewhere this list needs to be repopulated. I could of course put this list (or even the form bean) into session scope, but I thought that was to be avoided since the only thing this list is used for is this one page. To solve this problem I've been calling this business object to get my list in the reset() method and putting it back into scope. I've heard others say this is a bad idea(although I'm not sure why) and yet I haven't really heard any other'much better' solutions. I'll go out on a limb and say there aren't any a-Ha! solutions of staggering brilliance and philosophical purity. If there were, then somebody else would have already written about them (Hi, Ted!) I'll throw out my guidelines: (1) hidden fields are evil, and allow those bastard users to screw me over (2) things for this user belong in session scope (3) things for all users belong in application scope (4) the machinery (Struts et al.) uses whichever scope it likes (often request) #1 means I hardly ever think putting things in request scope is a good idea. I'm certainly not going to trust whatever comes back once the user touches it, so if I need to know it later then I'd better save it where the user can't touch it. That means that I keep all manner of things in session scope, like the aforementioned order list as well as all the model objects. Global object caches and their ilk live in application scope because database calls are too damned expensive to make unless it's really really necessary. paranoia-is-its-own-reward-ly y'rs, +Mitchell - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
