Re: Please help....Struts 1.0.2b and JDK 1.4.2
You asked exactly the same question only 24 hours ago. Patience is a virtue. ;-) Do you mean 1.0.2 beta? Wow, that's old! There is no reason that it shouldn't, but I haven't run anything that old for some time now. I would recommend upgrading to 1.1 anyway. :-) -- Martin Cooper Kramer, Brad [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Can anyone either confirm or deny if Struts 1.0.2b is compatible with JDK 1.4.2?

/* I think when I submit, the testBeanForm will automatically fill
its testBean's elements of their fontName attributes with font1 */

5.my action class file

ActionForm form,
HttpServletRequest servletRequest,
HttpServletResponse servletResponse)

{
System.out.println(stepped into action);
TestBeanForm bform=(TestBeanForm)form;
/*I stopped here to check if the form has its testBean variable filled

just the object I created in getTestBean(),that is, contains two elements,

return actionMapping.findForward(error);
}
}
so what on earth is the problem?

Yours resources is in the package com.struts.rs.resources? (and I presume its in that directory structure under your WEB-INF/classes) What happens if you set message-resources parameter=com.struts.rs.resources.ApplicationResources/ in struts config?

Subject: RE: Please Help - ClassCastException
Allow me to ask three more questions:
1. If I want to reset some specific text fields when
the JSP is re-displayed, do I code the PostForm.java
like this (please confirm):
code:
-
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
public class PostForm extends DynaValidatorForm
{
public void reset(ActionMapping mapping,
HttpServletRequest request)
{
super.reset( mapping, request );
set( receiver, new String() );
set( sender, new String() );
}
public PostForm () {}
}
*** Why not just use the intial attribute of the form-property
element?
---
2. if I want to reset all the text fields when the JSP
is re-displayed, do I code like this (please confirm):
code:
---
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
public class PostForm extends DynaValidatorForm
{
public void reset(ActionMapping mapping,
HttpServletRequest request)
{
initialize( mapping );
}
public PostForm () {}
}
--
*** Why not just use the intial attribute of the form-property
element?
3. What is the difference between
code:
---
form-bean
name=postForm
type=package.package.package.PostForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
/form-bean
---
AND
code:
--
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
/form-bean
---
Thank you very much.
*** The second one makes sense. Why do you need the PostForm
class?
see my answer to a similar question of yours at JavaRanch
http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topicf=58t=
001820
Here is a snippet of some tutorial I am working on that might help.
DynaActionForms are universally loved and hated. In teaching, consulting
Struts and developing with Struts, I have found that DynaActionForms are
either embraced or rejected. The idea behind DynaActionForms is that instead
of creating an ActionForm per form, you instead configure an ActionForm per
form.
Advantages of DynaActionForms:
Some folks feel creating an ActionForm class for each HTML form in your
Struts application is time-consuming, causes maintenance problems, and is
frustrating. With DynaActionForm classes you don't have to create an
ActionForm subclass for each form and a bean property for each field.
Instead you configure an DynaActionForm its properties, type, and defaults
in the Struts configuration file.
snip
To configure a DynaActionForm in struts-config.xml, you use a form-bean
element as with normal ActionForm. The type of the form bean must be
org.apache.struts.action.DynaActionForm or a derived class. You then add
form-property elements to declare the properties of the form.
To use a DynaActionForm add the following to form-beans element (example):
form-bean name=userRegistrationDynaForm
type=org.apache.struts.action.DynaActionForm
form-property name=userName
type=java.lang.String /
form-property name=email
type=java.lang.String /
form-property name=password
type=java.lang.String /
form-property name=passwordCheck
type=java.lang.String /
form-property name=firstName
type=java.lang.String /
form-property name=lastName
type=java.lang.String /
form-property name=phone
type=java.lang.String
initial=(520) /
form-property name=fax type=java.lang.String /
form-property name=page
type
RE: Please Help - ClassCastException
I am still confused...
I have a jsp that provides text fields for user to
fill out information. All the information is passed
via HttpRequest and to be validated. And all the
properties in my PostForm are populated by the
information retrieved from those text fields.
And my PostForm is of
type=org.apache.struts.validator.DynaValidatorForm
Therefore, in my PostForm.java, I should do something
like this? I just do not think the following code is
correct.
==
import org.apache.struts.validator.DynaValidatorForm;
public class PostForm extends DynaValidatorForm {
private String receiver;
private String sender;
public void set(String receiver, String receiver);
public void set(String sender, String sender);
public String get(String receiver, String
receiver);
public String get(String sender, String sender);
}

And you are saying that in my action class, I should

instead of calling setMyPropertyName(myString).
This is the Dyna part of
DynaForms. It's much less tedious IMHO.
In your action, you absolutely want to cast the form
to PostForm. Otherwise
the form variable has no way to know properties are
associated with it. So
yes, once you cast it to PostForm calls to
BeanUtils.copyProperties() can and
will work properly.
Hope this helps,

Subject: RE: Please Help - ClassCastException
I think that there are a lot more mistakes in my
code
than I originally thought. The root of the
problem is
that I do not know how to use DynaValidatorForm.
If
you could help me in learning how to code when I
am
working with DynaValidatorForm.
1. in my struts-config.xml, I have:
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
.
.
/form-bean
2. My PostForm.java is like:
import
org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
public class PostForm extends DynaValidatorForm {
private String receiver;
private String sender;
..
public void setReceiver( String receiver )
{
this.receiver = receiver;
}
public void setSender( String sender )
{
this.sender = sender;
}
public String getReceiver()
{
return receiver;
}
public String getSender()
{
return sender;
}
.
.
}
3. in my action class (see the code below)
3.1. do I cast the form to DynaActionForm? or I
should
cast the form to DynaValidatorForm?
3.2. Can I use the copyProperties() method of the
BeanUtils to convert the form to a bean?
BeanUtils.copyProperties
RE: Please Help - ClassCastException
Not at all.
First off, set(String, String) is predefined for you. You don't need to
create any of that. In fact, what you will find in a DynaValidatorForm is
that your form classes start to get very sparse. Here's really what it could
look like.
public class PostForm extends BaseDynaForm {
public void reset(ActionMapping actionMapping, HttpServletRequest
httpServletRequest) {
// throw new UnsupportedOperationException(Method is not
implemented);
}
public PostForm () {
}
}
In your ActionForm itself, beanUtils would work something like this. All you
need is to get the right formBean object.
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
PostForm pForm = (PostForm) form;
// other code you write here
BeanUtils.copyProperties(yourBean, pForm);
// etc
Doing it yourself without beanUtils?
Instead of calling getSender() and having a String returned, you call get
(sender) and it will return an Object (cast it yourself to whatever type
the sender form property really is). I made a base form class with a
getString method that calls get() and does the String cast for me to save the
tediom.
Making sense now?

I have a jsp that provides text fields for user to

Re: Please Help - ClassCastException
This passage is straight from the struts javadoc
The key passed into the validator is the action element's 'name' attribute
from the struts-config.xml which should match the form element's name
attribute in the validation.xml
Take a peek at how to configure struts-config.xml at
http://www.reumann.net/do/struts/lesson3/step4
which details the form bean name
type (with the fully qualified package name)
and the column form-property
Keep me apprised,
Martin

RE: Please Help - ClassCastException
Allow me to ask three more questions:
1. If I want to reset some specific text fields when
the JSP is re-displayed, do I code the PostForm.java
like this (please confirm):
code:
-
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
public class PostForm extends DynaValidatorForm
{
public void reset(ActionMapping mapping,
HttpServletRequest request)
{
super.reset( mapping, request );
set( receiver, new String() );
set( sender, new String() );
}
public PostForm () {}
}
---
2. if I want to reset all the text fields when the JSP
is re-displayed, do I code like this (please confirm):
code:
---
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
public class PostForm extends DynaValidatorForm
{
public void reset(ActionMapping mapping,
HttpServletRequest request)
{
initialize( mapping );
}
public PostForm () {}
}
--
3. What is the difference between
code:
---
form-bean
name=postForm
type=package.package.package.PostForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
/form-bean
---
AND
code:
--
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
/form-bean
---

RE: Please Help - ClassCastException
Here is what I see (opinions vary)...
I see you are defining your form bean in your struts-config.xml as type
'org.apache.struts.validator.DynaValidatorForm'. So, why are you trying to
cast it as this 'org.apache.artimus.message.PostForm' class. Does that
class extend DynaValidatorForm? If it doesn't, you'll get a
ClassCastException like you're getting now. Personally, I expected you to
cast it as:
DynaValidatorForm postForm = (DynaValidatorForm) form;
Or us it as-initially defined (not casting like above) and use BeanUtils
such as:
String receiver = (String) PropertyUtils.getSimpleProperty(form,
receiver);

David

RE: Please Help - ClassCastException
I think that there are a lot more mistakes in my code
than I originally thought. The root of the problem is
that I do not know how to use DynaValidatorForm. If
you could help me in learning how to code when I am
working with DynaValidatorForm.
1. in my struts-config.xml, I have:
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
.
.
/form-bean
2. My PostForm.java is like:
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
public class PostForm extends DynaValidatorForm {
private String receiver;
private String sender;
..
public void setReceiver( String receiver )
{
this.receiver = receiver;
}
public void setSender( String sender )
{
this.sender = sender;
}
public String getReceiver()
{
return receiver;
}
public String getSender()
{
return sender;
}
.
.
}
3. in my action class (see the code below)
3.1. do I cast the form to DynaActionForm? or I should
cast the form to DynaValidatorForm?
3.2. Can I use the copyProperties() method of the
BeanUtils to convert the form to a bean?
BeanUtils.copyProperties( threadBean, postForm );
...
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.DynaActionForm;
import org.apache.commons.beanutils.BeanUtils;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.artimus.message.PostForm;
import org.apache.artimus.message.PostBean;
import org.apache.artimus.message.ThreadBean;
import org.apache.artimus.message.utility.DateUtil;
public final class StoreMessage extends Action
{
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest
request,
HttpServletResponse
response)
throws Exception
{
int parentPostID;
int threadID;
String memberName = request.getRemoteUser();
Timestamp now =
DateUtil.getCurrentGMTTimestamp();
parentPostID = Integer.parseInt(
request.getParameter( parent ) );
DynaActionForm postForm = ( DynaActionForm
)form;
ThreadHandler thandler = new ThreadHandler();
ThreadBean threadBean = new ThreadBean();
BeanUtils.copyProperties( threadBean, postForm
);
if (parentPostID == 0 ) // new topic
{
threadBean.setLastPostMemberName( memberName
);
threadBean.setThreadCreationDate( now );
.
.
threadID = thandler.insertThread( threadBean
);
}
...
...
}
}
4. the action mapping in my struts-config.xml is like:
action
roles=administrator,editor,contributor
path=/message/NewTopic
type=org.apache.artimus.message.StoreMessage
name=postForm
scope=request
validate=true
input=.message.Form

name=success

/action
Thank you.

I see you are defining your form bean in your
struts-config.xml as type
'org.apache.struts.validator.DynaValidatorForm'. So,
why are you trying to
cast it as this
'org.apache.artimus.message.PostForm' class. Does
that
class extend DynaValidatorForm? If it doesn't,
you'll get a
ClassCastException like you're getting now.
Personally, I expected you to
cast it as:
DynaValidatorForm postForm = (DynaValidatorForm)
form;
Or us it as-initially defined (not casting like
above) and use BeanUtils
such as:
String receiver = (String)
PropertyUtils.getSimpleProperty(form,
receiver);

David

Thank you for trying to help. I have added
import org.apache.artimus.message.PostForm;
to my action class. I do not fully follow what I
should check in the struts-config.xml file. And
should I use name=postForm with lowercase 'p' or
uppercase 'P'?
In my struts-config.xml file, I have:
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
form-property
name
RE: Please Help - ClassCastException
Well, first off:
In your (dyna) form, you don't create setters and getters for the properties
though. With DynaForms you would say set(myPropertyName, myString)
instead of calling setMyPropertyName(myString). This is the Dyna part of
DynaForms. It's much less tedious IMHO.
In your action, you absolutely want to cast the form to PostForm. Otherwise
the form variable has no way to know properties are associated with it. So
yes, once you cast it to PostForm calls to BeanUtils.copyProperties() can and
will work properly.
Hope this helps,
-Joe

I need your sharp eyes and experience. I keep
getting this error message in the browser:

This postForm.jsp had worked find before I inserted:

html:text property=creator value=bean:write
name=author/ size=82 maxlength=25

And the error message points at the bean:define ...

wrapped around) in my file.
cr is passed to the postForm.jsp in a session object
this way:
c:set var=cr value=${articleForm.creator}

C,
You can't nest tags as you did in the value attribute.
bean:define ... value=bean:write name=author/ /
The rest of the list will croak when I recommend that you use
%= author %
instead of
bean:write name=author/
Maybe they can tell you a fancy -el/JSTL way to do it. :)

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction
Hi Caroline,
have you checked the source of the HTML page in the browser to see what
the value of username is, client-side? I expect the value is being sent
to the browser as null.
If that is the case, it is because request.getRemoteUser() is returning
null and that would be because you don't have or are losing your login
session.

The value of the 'username' is found to be a 'null' in
the FindEditorData.java while the value of keyName is

Re: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction
Rats, the thread broke, hence my other reply. Like everyone says, you
need to check the return value of getRemoteUser() - try looking at the
value of the hidden field in the HTML via IE's 'Show page source'.

It is impossible for request.getRemoteUser(); in my

reaches request.getRemoteUser(); the user has already
been successfully logged in with a valid name.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction
I followed your advice. In the Bean.java, I did the
following:
private String username = natalie;
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}
and I compiled all the relevant classes, re-run the
application, the FindEditorData.java writes out the
following in the browser:
The process did not complete. Details should follow.
name=natalie; kn=journal_category; kv=null
Now, the question is why the Bean.java does not pick
up the value of the hidden field 'username' from my
JSP while successfully picks up the value of the other
hidden field 'keyName'.
There is some data processing activities going on in
the FindEditorData.java:
String username = getUsername();
EditorService service = new EditorService();
String value = service.findEditorData( username );
The above data accessing codes had been tested outside
the environment of the application (the codes did what
I expected them to do without problem) before they
were integrated into the application.

null,
then you are reading the wrong request parameter

Why don't you dump request parameters that you

I did another test. I took out those data access

of data access activities have nothing to do with the
value of the 'username' becoming null in the
FindEditorData.java.

As the JavaDoc says: Whether the user name is sent with each subsequent

If you are doing it yourself (ie. through a db lookup) then the server

hidden field I want to pass from my JSP to the
scaffold.ProcessAction.
If it had been the lowercase/uppercase problem, I
would
have gotten a message
saying that the variable could not be recognized.
I pass two hidden fields at the same time. One of
them is successfully passed with correct value.
The
other is passed but its value shows a 'null' in
the
scaffold.ProcessAction. What could go wrong? Let
me show my code
again:
Two hidden fields: username and keyName are passed
from a JSP via a SUBMIT button:
req:isUserInRole role=editor
html:form action=/find/Category
% String username = request.getRemoteUser();%
html:hidden property=keyName
value=journal_category/
html:hidden property=username
value=%=username%/
html:submitView Articles/html:submit
/html:form
/req:isUserInRole
and an action mapping:
action
roles=editor
path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.apache.artimus.article.FindEditorData
name=articleForm
scope=request
validate=false
forward
name=success
path=.article.Result/
/action
The value of the 'username' is found to be a
'null'
in
the FindEditorData.java while the value of keyName
is successfully
retrieved. In the browser, I got:
name=null; kn=journal_category; kv=null
The code of my FindEditorData is shown below:
public final class FindEditorData extends Bean
{
public Object execute() throws Exception
{
// Obtain username
String username = getUsername();
EditorService service = new EditorService();
String value = service.findEditorData( username
);
String property = getKeyName();
if (( null==property ) || ( null==value ))
{
StringBuffer sb = new StringBuffer();
sb.append( name= );
sb.append( username );
sb.append( ; kn= );
sb.append( property );
sb.append( ; kv= );
sb.append( value );
throw new ParameterException(
sb.toString() );
}
ResultList list = new ResultListBase

Caroline,
Did you check the result of getRemoteUser(). Does it return null or null?
If so, it's not a problem with your hidden form variables,.

Imposible? Look at the HTML that is generated by the
JSP page. I think you
will see that it returns null.
Take a look at the JavaDoc for
HttpServletRequest.getRemoteUser();
getRemoteUser
public java.lang.String getRemoteUser()
Returns the login of the user making this request,
if the user has been
authenticated, or null if the user has not been
authenticated. Whether the
user name is sent with each subsequent request
depends on the browser and
type of authentication. Same as the value of the CGI
variable REMOTE_USER.
Returns: a String specifying the login of the user
making this request, or
null
As the JavaDoc says: Whether the user name is sent
with each subsequent
request depends on the browser and type of
authentication. Are you using
basic authentication or are you authenticating the
user yourself?
If you are doing it yourself (ie. through a db
lookup) then the server
doesn't know about the user being authenticated and
will return null.

Richard

I pass two hidden fields: username and keyName at

Why are you passing the result of request.getRemoteUser() in a hidden
variable anyway since it is available as part of the HttpRequest and thus
will be available in the action class?

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction
I must pass the result of request.getRemoteUser()
because it is a Java class that receives the
hidden field. If you read my code carefully, you will
see that FindEditorData.java is a Java class and I
cannot use 'request' or 'session' in a Java class. It
takes a servlet or a class extends Action to use
'request' or 'session'.
But, this class is of ProcessAction type defined in
the struts-config.xml:
action
roles=editor
path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.apache.artimus.article.FindEditorData
name=articleForm
scope=request
validate=false
forward
name=success
path=.article.Result/
/action
And, it is easy to see that I use container-managed
authentication. In my JSP, there is req:isUserInRole
role=editor before reaching % String
username=request.getRemoteUser(); % Again, I have
provided my code:
req:isUserInRole role=editor
html:form action=/find/Category
% String username = request.getRemoteUser(); %

the way, I do not use 'request' to retrieve the value

Re: Please Help!!! A Validation Rule Fail On A Second-Page Causes A Blank Page To Show Up
Hi Ted, Thank you for your time in helping me out. After your email message I take a hard look at the jsp file and can not find what was wrong with it. The secondPage.jsp is almost the same as the firstPage.jsp. When I move all the code from the secondPage.jsp to the firstPage.jsp the validation process went fine. All fields are validated by the validator. I have given up the hope to create a multipage form for now. And by the way I have purchased the Struts In Actions book along with other three books on the same subject. But there was not must information on multipage form. Do you have any suggestion on book that I may find some complete example on multi page form. To answers your your question about why do I reset all input fields to its original state when the getPage() is equal to 2 is that I only have two pages,firstPage.jsp and secondPage.jsp, each page would set the page number to 0 and 1 correspondingly. I set the page to 2 in the action class when the secondPage.jsp was executed. Then I call the form's reset method to clear all the fields before the control goes back to the firstPage.jsp. I guest you are right about removing the form bean should be good enough to remove all attributes in form for both pages. Thank again.

Sometimes the page doesn't render because of errors in the HTML, which might only be exposed when the page is trying to display error messages. I'm not sure why you would reset everything if getPage() is equal to 2. The usual approach is to allow the properties to accumulate, until the end of the workflow, and then dispose of the (session-scoped ActionForm altogether. Generally, the only thing you ever need to reset is a checkbox to false on a session-scope ActionForm. -Ted. Hi, I have been looking at this problem for the last four days and can't figure out. I have an application that required workflow form. I created a CreateUserAccountAction class that extends the DispatchAction and a form MultiCreateUserAccountForm that extends the ValidatorForm. The reset method of the MultiCreateUserAccountForm clears all attributes under the current session when the getPage() is equal to 2. The CreateUserAccountAction has two methods that are similar to the execute method that are named createUserAccountActionOne and createUserAccountActionTwo. I got this concept out of chapter 12 of the book Profession Jakarta Struts by James Goodwill and Richard Hightower. *** Here are the symptoms ** If there is a required field that is missing (leaved out) or does not fulfill the validation rule on the firstPage.jsp when the submit button is pressed. A new dialog box popped up on the screen with the validation message(s) from the resource property file. When all fields are validated the control is forwarded to the secondPage.jsp. If there is a required field that is missing (leaved out) or does not fulfill the validation rule on the secondPage.jsp when the submit button is pressed. A blank page is showed up on the window without a new dialog box shows up on the screen. The server.log indicates an error occurred and the control returns to the same page (secondPage.jsp). To fixing this problem, I pressed the back page button of the browser and correctly filled in all missing fields or making sure the input is conforming to the validation rule. When all fields on the second page are filled in correctly according to the validation rules then the control is correctly forwarded back to the firstPage.jsp. ** My questions Any suggestion and how to fix this problem is deeply appriciated. Kam Lung Leung *** ***More detail on how the jsp was set up ** The createUserAccountActionOne method calls the MultiCreateUserAccountForm.validate() method to validate the user input fields of the firstPage.jsp. Second, it calls the setPage() method with 1 as its input parameter. Finally, it calls the MultiCreateUserAccountForm.setMethodToDispatch() with createUserAccountActionTwo as the input parameter. The createUserAccountActionTwo method calls the MultiCreateUserAccountForm.validate() method to validate the user input fields of the secondPage.jsp. Secondly, it remove the obsolete form bean with session.removeAttribute(mapping.getAttribute()). Thirdly, it calls the setPage() method with 2 as its input parameter. Finally, it calls the reset() method to clear all attributes under the current session. ** This are action

Re: please help: ActionForms of same type but different name?
Are the number of different form instances going to be determined
dynamically? If so, this is an intractible problem, because you won't be
able to make every possible determination in the struts-config.xml file
in advance.
This might be a good use of JavaScript though. In that case, you would
have two form beans: LoginFormA, and LoginFormB. Each one would have one
potential action coming out of the page (ActionA and ActionB).
You would then create one hidden html:form instance of each of
LoginFormA, and LoginFormB.
For each visible html:form, you would have a form which, on submit,
would populate the hidden LoginFormA or LoginFormB instance, setting a
hidden value indicating which visible html:form was actually
submitted, and then submit the HIDDEN html:form corresponding to the
particular form bean you needed to use.
Would this pattern work for you?

So there are two levels of distinction here - the first one being

So when m of n is submitted, the request processor knows whether
m is of type LoginFormTypeA or of type LoginFormTypeB. Problem
is that you cannot have multiple html:form elements on a page,
all with the same name LoginFormTypeA or LoginFormTypeB.
This is why we gave them different names through iteration-
LoginFormA_1, LoginFormA_2, LoginFormB_1,
etc. When LoginFormA_1 is submitted, you would think that
the request processor would look for a form called LoginFormA_1
and form.get(userName) would return the value of LoginFormA_1's
userName property. This doesn't happen.
Instead, the request processor looks at the action associated with the
submitted form, sees that it is loginActionA, looks for the
associated form (which from the action-mapping is LoginFormTypeA)
and since it cannot find one, creates one. Thus form.get(userName)
returns null.
Hope this is not too confusing!

There is no knowing until runtime how many iterations there are
going to be.
That's why we can't define the n number of LoginForms.
The requirement is that on the same jsp, we will have repeating
html:form/html:form sections. User will specify at runtime
how many he/she wants. The html:forms will all be of the same
type. Restriction is that only one can be submitted at a time, i.e.
user
might have specified 5 Login sections of the page, and therefore is
shown 5
login sections, but can only save one at a time.
The save action needs to know which form to retrieve the values

Re: please help: ActionForms of same type but different name?
There is no knowing until runtime how many iterations there are going to be. That's why we can't define the n number of LoginForms. The requirement is that on the same jsp, we will have repeating html:form/html:form sections. User will specify at runtime how many he/she wants. The html:forms will all be of the same type. Restriction is that only one can be submitted at a time, i.e. user might have specified 5 Login sections of the page, and therefore is shown 5 login sections, but can only save one at a time. The save action needs to know which form to retrieve the values username and password from. SB Chen, Gin wrote: One approach, you can define as many form-beans as you want iteratations. Ex: form-bean name=LoginForm_1 type=com.oreilly.struts.storefront.security.LoginForm /form-bean form-bean name=LoginForm_2 type=com.oreilly.struts.storefront.security.LoginForm /form-bean . . . form-bean name=LoginForm_n type=com.oreilly.struts.storefront.security.LoginForm /form-bean You can also just use a single form bean for all your actions.. If they are the same class then they are the same formbean anyways. So just use the same name for all of them (well not html:form name in Struts 1.1+ but rather use name in action definition). Or If you explain your requirements a bit more we could come up with a better solution/explanation. -Tim -Original Message- From: Sonam Belbase [mailto:[EMAIL PROTECTED] Sent: Monday, October 27, 2003 6:16 PM To: Struts Users Mailing List Subject: please help: ActionForms of same type but different name?

Re: Please Help!!! A Validation Rule Fail On A Second-Page Causes A Blank Page To Show Up
Kam Lung Leung wrote: Why don't I get a pop up dialog box with error messages? Why the secondPage.jsp did not get executed when a validation error occurred? Why do I get a blank screen? Are you sure that it's blank? Sometimes the page doesn't render because of errors in the HTML, which might only be exposed when the page is trying to display error messages. I'm not sure why you would reset everything if getPage() is equal to 2. The usual approach is to allow the properties to accumulate, until the end of the workflow, and then dispose of the (session-scoped ActionForm altogether. Generally, the only thing you ever need to reset is a checkbox to false on a session-scope ActionForm. -Ted. Hi, I have been looking at this problem for the last four days and can't figure out. I have an application that required workflow form. I created a CreateUserAccountAction class that extends the DispatchAction and a form MultiCreateUserAccountForm that extends the ValidatorForm. The reset method of the MultiCreateUserAccountForm clears all attributes under the current session when the getPage() is equal to 2. The CreateUserAccountAction has two methods that are similar to the execute method that are named createUserAccountActionOne and createUserAccountActionTwo. I got this concept out of chapter 12 of the book Profession Jakarta Struts by James Goodwill and Richard Hightower. *** Here are the symptoms ** If there is a required field that is missing (leaved out) or does not fulfill the validation rule on the firstPage.jsp when the submit button is pressed. A new dialog box popped up on the screen with the validation message(s) from the resource property file. When all fields are validated the control is forwarded to the secondPage.jsp. If there is a required field that is missing (leaved out) or does not fulfill the validation rule on the secondPage.jsp when the submit button is pressed. A blank page is showed up on the window without a new dialog box shows up on the screen. The server.log indicates an error occurred and the control returns to the same page (secondPage.jsp). To fixing this problem, I pressed the back page button of the browser and correctly filled in all missing fields or making sure the input is conforming to the validation rule. When all fields on the second page are filled in correctly according to the validation rules then the control is correctly forwarded back to the firstPage.jsp. ** My questions Any suggestion and how to fix this problem is deeply appriciated. Kam Lung Leung *** ***More detail on how the jsp was set up ** The createUserAccountActionOne method calls the MultiCreateUserAccountForm.validate() method to validate the user input fields of the firstPage.jsp. Second, it calls the setPage() method with 1 as its input parameter. Finally, it calls the MultiCreateUserAccountForm.setMethodToDispatch() with createUserAccountActionTwo as the input parameter. The createUserAccountActionTwo method calls the MultiCreateUserAccountForm.validate() method to validate the user input fields of the secondPage.jsp. Secondly, it remove the obsolete form bean with session.removeAttribute(mapping.getAttribute()). Thirdly, it calls the setPage() method with 2 as its input parameter. Finally, it calls the reset() method to clear all attributes under the current session. ** This are action mapping *** action path=/multiCreateUserAccountFirstSubmit type=com.wlwa.CreateUserAccountAction name=multiCreateUserAccountForm scope=session validate=true parameter=methodToDispatch input=/CreateUserAccountLink.jsp forward name=success path=/CreateUserAccountSecondLink.jsp / /action action path=/multiCreateUserAccountSecondSubmit type=com.wlwa.CreateUserAccountAction name=multiCreateUserAccountForm scope=session validate=true parameter=methodToDispatch input=/CreateUserAccountSecondLink.jsp forward name=success path=/CreateUserAccountLink.jsp / /action - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Ted Husted, Junit in Action - http://www.manning.com/massol/, Struts in Action - http://husted.com/struts/book.html, JSP Site Design - http://www.amazon.com/exec/obidos/ISBN=1861005512. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Please help with this error ???en_US.errors.required???
Hi Vivien,
Take a look at your web.xml. Maybe you copied it from Struts dist and
message-resources was
already configured there. As settings in web.xml will override settings in
struts-config.xml,
classloader can't find resource to be loaded and then you get that messages.
Hope i helped you.

RE: Please help with this error ???en_US.errors.required???
Hi Vivien,
I think it depends on Struts version you are using. I use 1.1 and everything works
fine.
Your message-resources/ config tells Struts to look for your resources at package
org.apache.struts.webapp.tiles.dev1-1. So, you should have, for instance, this:
WEB-INF
--
|
|--- classes
--
|
|--- org/apache/struts/webapp/tiles/dev1-1
|
| - ApplicationResources.properties
If you are not using 1.1, please, upgrade to. If problem still happens, you know how
to find us.
Hope it was useful.

Daniel.

Re: Please Help Me To Understand forward
The first snippet redirects to a Struts ActionForward named welcome. This places controls within the Struts controller where it can be managed from the struts-config. In the global-forwards section, the ActionForward element for welcome is mapped to the page /do/Menu. This application uses prefix mapping, so any request for /do/* is sent to the Struts ActionServlet. The Struts ActionSerlvet then looks for a matching ActionMapping. The matching ActionMapping in this case is /Menu (the URI stripped of the prefix or suffix registered to the Servlet). If you look again, I think you will find this ActionMapping: action path=/Menu name=menuForm type=org.apache.struts.scaffold.ExistsAttributeAction parameter=application;HOURS forward name=success path=.article.Menu/ forward name=failure path=/do/MenuCreate/ /action Here, if the attribute exists, the page will be rendered by the .article.Menu Tile. Otherwise, control will go the /MenuCreate action first. The .article.Menu tile (in tiles-def.xml) assembles the page using these instructions: definition name=.article.Menu extends=.article.Base put name=title value=article.Menu.title/ put name=content value=/article/content/menu.jsp/ put name=navbar value=/article/common/navbarMenu.jsp/ /definition The menu.jsp is the main content page, but other pages are also used to create the final response. -Ted.

Sorry to plead, but I have been fighting this for the better part of two
days now. I've done a line by line review of just about all of my code.
Cannot find anything that appears out of whack - compared to similar
programs that are working.
Would really appreciate any tips or suggestions on how to track this down.
Let me know if there is additional documentation needed.
First, I am running the regular Struts 1.1 production release on
Windows XP
using Sun Java 1.4.1.
In my main JSP I'm running into some type of exception that is
causing me to
switch to my error.jsp. However it never makes it there and I get
about 2/3
of my original JSP page. This only occurs when I encounter an error in a
multi-line update.
I've turned on logging for the tiles and appropriate struts classes. The
most I can see is that I'm getting an NPE in:
org.apache.struts.taglib.html.MessagesTag.doAfterBody(MessagesTag.
java:312)
Below is my error.jsp file and the exception stack trace (sorry, its long
chain of exceptions). Each exception refers to the same line in my main
JSP - 849 - which is this line, I've just finished the /tiles:put tag
for an inline put, and am encountering the /tiles:insert to
end my tiles
structure (I've included several lines after it):
/*line 849*/ if (_jspx_th_tiles_insert_0.doEndTag() ==
javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
return;
_jspx_tagPool_tiles_insert_flush_definition.reuse(_jspx_th_tiles_i
nsert_0);
out.write(\r\n);
out.write(!-- html-el:javascript formName=\subjectAspectsForm\
dynamicJavascript=\true\ staticJavascript=\true\ htmlComment=\true\
cdata=\false\/ --\r\n\r\n);
} catch (Throwable t) {
out = _jspx_out;
if (out != null out.getBufferSize() != 0)
out.clearBuffer();
if (pageContext != null) pageContext.handlePageException(t);
} finally {
if (_jspxFactory != null)

Sorry to plead, but I have been fighting this for the better part of two
days now. I've done a line by line review of just about all of my code.
Cannot find anything that appears out of whack - compared to similar
programs that are working.
Would really appreciate any tips or suggestions on how to track this down.
Let me know if there is additional documentation needed.
First, I am running the regular Struts 1.1 production release on
Windows XP
using Sun Java 1.4.1.
In my main JSP I'm running into some type of exception that is
causing me to
switch to my error.jsp. However it never makes it there and I get
about 2/3
of my original JSP page. This only occurs when I encounter an error in a
multi-line update.
I've turned on logging for the tiles and appropriate struts classes. The
most I can see is that I'm getting an NPE in:
org.apache.struts.taglib.html.MessagesTag.doAfterBody(MessagesTag.
java:312)
Below is my error.jsp file and the exception stack trace (sorry, its long
chain of exceptions). Each exception refers to the same line in my main
JSP - 849 - which is this line, I've just finished the /tiles:put tag
for an inline put, and am encountering the /tiles:insert to
end my tiles
structure (I've included several lines after it):
/*line 849*/ if (_jspx_th_tiles_insert_0.doEndTag() ==
javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
return;
_jspx_tagPool_tiles_insert_flush_definition.reuse(_jspx_th_tiles_i
nsert_0);
out.write(\r\n);
out.write(!-- html-el:javascript formName=\subjectAspectsForm\
dynamicJavascript=\true\ staticJavascript=\true\ htmlComment=\true\
cdata=\false\/ --\r\n\r\n);
} catch (Throwable t) {
out = _jspx_out;
if (out != null out.getBufferSize() != 0)
out.clearBuffer();
if (pageContext != null) pageContext.handlePageException(t);
} finally {
if (_jspxFactory != null)
_jspxFactory.releasePageContext(pageContext);
}
}
HERE'S the error.jsp:

RE: Please Help With Simple Tiles Problem
Thanks for your response. Your assumption is correct in that my design is not very static and therefore need the ability of dynamic embedded tiles (so the first solution would not work). However, you did give me some good ideas and insight into how Tiles works. What I got out of all of this is is that it seems Tiles was intented to work better with flatter structures rather than this dynamic, tree structure thing I'm trying to implement (tiles within tiles within tiles, branching off into other tiles, etc). It certainly has that capability but my definition.xml is getting UGLY... but it's worth it ;) --- Holman, Cal [EMAIL PROTECTED] wrote: Terry Hard to tell from a snippet of an entire site but if the definition page does not define anything except the page.jsp and if you always have form_wrapper.jsp around each for then you could move form_wrapper.jsp functionality to page.jsp and simplify the design. The other way to reduce is to have the functionality for form_wrapper .jsp in the formX.jsp. The tiles context is only for the definition being used not for any embedded definitions so unless you take measures to pass attributes down tiles will not see them. I pass the page definition being called for some menuing style changes but to do so you need to define a bean with the attribute in request scope then pluck it in the lower tiles definition. I have an example on my web site - if you look for the code for the level 3 index you will see the same technique: http://www.calandva.com/holmansite/do/blog/blogging. Although I have been having a lot of problems with my DSL connection over the last few weeks - so email me if you would like more info. If you must do the nested definitions then you can pass the inner tiles insert parameter as a bean and script the formX.jsp. This is pretty ugly and Cedric or someone else may know a better way - I just hacked this together. First the hack: In form_wrapper.jsp add this line where you want form1.jsp to be inserted: tiles:insert name=%= request.getAttribute(form).toString() % flush=true / Then in page.jsp you need to do two things the easy one is include form_wrapper.jsp: tiles:insert attribute=body flush=true/ or you could use your def calling a def routine. Also in page.jsp include a line near the top of the page prior to any tiles:insert tags to create the request scope bean this will make the form visible to the next tile: tiles:useAttribute id=form name=form scope=request/ Now the definition can look like this: definition name=page path=page.jsp/ definition name=form_type_page extends=page put name=body value=form_wrapper.jsp put name=form value=form1.jsp/ /definition definition name=form_page2 extends=form_type_page put name=form value=form2 /definition I know it is messy - but it should work.

So the alternative, I guess, is to have another action that NEVER

have one of these... it's my create action.
Aaron, this sounds like a good idea if it works for you. You can also
manually validate in your save action (the action your form submits to)
by doing something like:
// Validate form parameters ...
ActionErrors errors = yourForm.validate(mapping, request);
if (errors != null !errors.isEmpty()) {
saveErrors(request, errors);
//do whatever you need to do to put your
//drop-down list values back into the request.
return new ActionForward(mapping.getInput());
}// end validate
And set validate=false in your edit action mapping.
Susan Bradeen
This appears to be the best practice in this situation anyone else
have any feedback?
Thanks again,
Aaron

You have at least 2 choices.
1) You can put your drop-down values into session scope.
2) You can set the input attribute of your action mapping to your edit

I start getting quite frustrated on this issue after a few days of
researching on the Tiles home page, Tiles Struts home page, Struts email
archive, the tiles-documentation.war, and google on Tiles. The whole
development is stop at this point.
I have read somewhere at the email archive: it is not need to process the
initialition if the definition is stored in a JSP file, which is the case
I posted my previous post.
I change the definition method, using a xml file instead. After having a
xml file and modification of web.xml, I get the logging message when I

Re: Please help a Tiles problem
I start getting quite frustrated on this issue after a few days of
researching on the Tiles home page, Tiles Struts home page, Struts email
archive, the tiles-documentation.war, and google on Tiles. The whole
development is stop at this point.
I have read somewhere at the email archive: it is not need to process the
initialition if the definition is stored in a JSP file, which is the case I
posted my previous post.
I change the definition method, using a xml file instead. After having a
xml file and modification of web.xml, I get the logging message when I
start/reload the applicaiton:

I noticed in your debug output that you're using TilesServlet. Are you
using Struts 1.1? You don't need the TilesServlet; all you need is to
configure the TilesPlugin.

Where the plug-in configuration shall go? I don't use Struts, but Tiles
only. According to the document on tiles-documentation.war, the
TilesServlet shall be used, if my understanding is correct.

Re: Please help a Tiles problem
Thanks very much for your information, Cedric.
I have read through the Tiles related articles linked to the Struts-Tiles
page, and have not seen the plug in procedure for standalone usage. A
plugin procedure, I find, is on the following page
http://www.onjava.com/pub/a/onjava/excerpt/progjakstruts_14/index2.html. It
is about Struts. I don't use Struts however. How I initialize the Tiles?

I don't know, but my guess is that you meant to use
someString.equals(someOtherString) rather than someString ==
someOtherString, unless you somehow are using a hidden myString.intern() in
there. My guess, in other words, is that you are getting nothing because
all your == tests yield false. Try sticking a ! or two in there and

RE: Please help decide a religious discussion
+1 on initializing static data at application start up time and caching it. In addition we found that putting the Collection directly into some scope with a well defined Constant.KEY_XXX was much better in the long run as opposed to trying to put in the form bean. This way the control on the page only needs to know the name of the collection but not where to get it. Why not just populate the form with the collection and use the nested tags to render the data from the form. This way you don't have to manage any attribute keys and the nested control only needs to know which property to access. robert -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, September 27, 2002 11:38 AM To: Struts Users Mailing List Subject: RE: Please help decide a religious discussion We have done alot of this and have tried many things.

In the case of validation we route back to the LoadAction and not the page. The only problem is that this forces us to consider when to pre-populate the form fields from the backend or let them be prepopulate from the request(in the case of a bad validation). There is usally some type of a flag in the page that will let us know what state the page is in. In addition we found that putting the Collection directly into some scope with a well defined Constant.KEY_XXX was much better in the long run as opposed to trying to put in the form bean. This way the control on the page only needs to know the name of the collection but not where to get it. As well we now use LabelValueBeans for every list. just my 2 canadian cents.

Correction, it seems that the version of Tomcat doesn't matter after all. A
JSP with nested logic:iterate tags worked before, but not now. Maybe it
was with an earlier version of Struts. Does anyone know if the behavior of
logic:iterate changed with respect to nesting the tags between Struts 1.0
and Struts 1.1b?

No. You could reference it as ${requestScope['key']} I believe. In

that may work too. I always go through the scope ...

Re: Please help decide a religious discussion
Put the list of objects to go in your select box in the session. Your jsp will use that session attribute to populate the select box, either using a struts tag or anything else. Your ActionForm only needs a String variable to hold the one option the user selected (for multiple selects I assume you'll need a String array). The ActionForm doesn't actually hold all of the choices just the selected value.
