Re: Please help....Struts 1.0.2b and JDK 1.4.2

[Martin Cooper]

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. :-)

Can anyone either confirm or deny if Struts 1.0.2b is compatible with
JDK 1.4.2?


Thanks a lot!

decided to explain detailedly and completely of what I did and hope you 
nice buddies can help me find the problem


goal: I want to submit an array of Fonbean(java class file listed below) to 
an action
strategy: I decide to use html:form and logic:iterate to do this

1.what I have in my configruation xml


type="com.mycom.form.TestBeanForm"/>



type="com.mycom.action.TestAction"
name="testBeanForm"

if(testBean==null)
{
testBean=new FontBean[2];
testBean[0]=new FontBean();
testBean[1]=new FontBean();
}
return testBean;
}

public void setTestBean(FontBean[] testBean) {
this.testBean = testBean;
}

FontBean[] testBean;
}


3. FontBean.java

public class FontBean {
public int getSize() {
return size;
}

public void setSize(int size) {
this.size = size;
}

public String getFontName() {
return fontName;
}

public void setFontName(String fontName) {
this.fontName = fontName;
}

private int size;
private String fontName;

}

4. my jsp file


type="com.mycom.bean.propertybean.FontBean" id="mybean" indexId="index1">
indexed="true"/>

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


Submit Changes



5.my action class file

public class TestAction extends Action {
public ActionForward execute(ActionMapping actionMapping,
ActionForm form,
HttpServletRequest servletRequest,
HttpServletResponse servletResponse) 
throws Exception
{
System.out.println("stepped into action");
TestBeanForm bform=(TestBeanForm)form;

/*I stopped here to check if the form has its testBean variable filled 
with
"font1" of its fontName attribute, but it doesnt, the testBean of form is 
just the object I created in getTestBean(),that is, contains two elements, 
both the fontName attributes of the two elements are null */

return actionMapping.findForward("error");
}
}



so what on earth is the problem?

Thank you so much for your help. I started from scratch again this morning.  I created 
a new project in Eclipse and imported my files one by one double checking the 
directory structure each time. I also was sure to include the message resources tag in 
the struts-config.xml file. This resolved my problem. Thanks again for your help and 
good -bye to that nasty error message :-)

Hehe, dont let trolls like me scare you away from asking questions. ;-)
The struts list is actually one of the friendliest and helpful mailing lists
there is.

Actually I think that this question comes up quite a bit on the list. Im not
sure of the answer myself, but a search of the archives will probably turn
up some helpful posts.

The archives can be found at:
http://mail-archives.apache.org/eyebrowse/SummarizeList?listId=42

But Ive always found that one a pain to search, so Id suggest trying the
copy at MARC:
http://marc.theaimsgroup.com/?l=struts-user&r=1&w=2

hmmm.

do you have a  element entry in your struts-config.xml?

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



in struts config?

(This goes after the  element in the struts config, which comes

I think you are missing this :





Where  resources is the directory within WEB-INF and
application.properties is the properties file. 

You may put the null = "true" to get null value if there is a message
missing. I personally prefer "false" as I can catch any errors that may
not have been defined in the properties file 

Put this after the   tag in struts-config.xml and see
if it works.

RE: Please Help - ClassCastException

I've been responding to your questions here and at JavaRanch on this
subject.

It seems like you are missing the point of DynaActionForms.

Please read 4.3 and 4.4 of the user guide.

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:

AND

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_topic&f=58&t=
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.

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):
 

 
 
 
 
 
 
 
 
 
  

Then create an action mapping that uses this ActionForm:

  ...
  
  


Then modify the Action to use the new DynaActionForm:
public class UserRegistrationAction extends Action {

 ...
public ActionForward execute(...
  /* Cast the form into a DynaActionForm */
   DynaActionForm userDynaForm =
 (DynaActionForm) form;
log.debug("userForm email " +
   userDynaForm.get("email"));

Notice how the action accesses the email property of the DynaActionForm
(userDynaForm.get("email")). Working with DynaActionForms is a lot like
using a HashMap.
The nice thing about DynaActionForms is that the BeanUtils framework treats
them just like regular JavaBeans. Thus, the following code does not really
change from the static version of ActionForm as follows:
/* Create a User DTO and copy the properties
 from the userForm */
User user = new User();
BeanUtils.copyProperti

RE: Please Help - ClassCastException

[Caroline Jen]

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

AND

Re: Please Help - ClassCastException

[Martin Gainty]

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,

Here is the problem. Replace

org.apache.struts.validator.DynaValidatorForm

for

org.apache.artimus.message.PostForm

That should work

RE: Please Help - ClassCastException

[Joe Hertz]

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?

RE: Please Help - ClassCastException

[Caroline Jen]

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

...
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.commons.beanutils.BeanUtils;

import org.apache.artimus.message.PostForm;

{
   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" ) );
 
  ActionForm postForm = ( ActionForm )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

RE: Please Help - ClassCastException

[Joe Hertz]

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

RE: Please Help - ClassCastException

[Caroline Jen]

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:

 
  
  
  .
  .


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:

RE: Please Help - ClassCastException

[David Friedman]

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");

Regards,
David

Re: Please Help - ClassCastException

[Pedro Salgado]

  On your struts config file check if the form bean for StoreMessage action
is of type pkg.pkg.PostForm and if the action name is pointing to the
correct form bean... It also seems to be missing the import of the PostForm
on your action class.

yes, if you use html-el:text instead then you should be able to use an el

Re: Please Help With This Error Message

[Caroline Jen]

Hi, I tried and tried.  I cannot figure out the error.
 I need your sharp eyes and experience.  I keep
getting this error message in the browser:

ServletException in:/article/content/postForm.jsp]
/article/content/postForm.jsp(32,67) equal symbol
expected' 

This postForm.jsp had worked find before I inserted:


" size="82" maxlength="25"
tabindex="1"/>

And the error message points at the 
tag.  The statements are in ONE line (they do not
wrapped around) in my file.

"cr" is passed to the postForm.jsp in a session object
this way:

 

Thanks a lot.

maybe you don't have a space character between "creator" and scope... try to
write the tag in one line, not multiple lines.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Caroline Jen]

I did another test.  I took out those data access
activities in the FindEditorData.java and ran the
application.  The conclusion is that those few lines
of data access activities have nothing to do with the
value of the 'username' becoming null in the
FindEditorData.java.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Caroline Jen]

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.

Caroline,
As a sanity check, in your bean, initialize the
username variable to something ie. "XX". and
re-run your app. This will show if your setUsername is
ever called.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Richard Yee]

Caroline,
In your FindEditorData.java class, is the value for
your username variable null or "null"?  If it is null,
then you are reading the wrong request parameter since
request.getParameter() will return null if the
parameter doesn't exist. If the String value is
"null", then you have a problem with getRemoteUser()
Why don't you dump request parameters that you are
getting in your FindEditorData?

Hidden input tags work fine.

Richard

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Caroline Jen]

Hi, I think that we are in different time zones.

As you have mentioned, I, too, suspected that the
statement in my JSP:

request.getRemoteUser(); 

returns nothing.  Therefore, I did a test in my JSP. 
In addition to request.getRemoteUser(); I created
another String manually:


<% 
   String username = request.getRemoteUser(); 
   String userrole = "author"; 
%>   
<% out.println("The user name is: " + username +".");
%>
<% out.println("The role is: " + userrole +"."); %>


And the browser shows:

The user name is: Gloria Jen.  The role is: author. 

Gloria Jen is the name that I provided while logging
on and authenticated by the container.  Therefore, the
request.getRemoteUser(); does not return a null.  And
I hope that it means I am not passing a null value
when I use the hidden field technique.

Then, I pass two hidden fields (with value in them)
from my JSP to a Java class (FindEditorData.java),
which is of scaffold.ProcessAction type.  One of the
field is passed with its value correctly retrieved. 
The other field is passed with its value found to be
null.

What could go wrong?  I have been thinking about it
for days and so do those who try to help me.  



<% 
   String username = request.getRemoteUser(); 
   String userrole = "author"; 
%>   
<%out.println("The user name is: " + username +".");%>
<%out.println("The role is: " + userrole +".");%>

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
JSP returning a null.  (see code below) Before it
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.ProcessAction

[Adam Hardy]

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.

Caroline,
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?

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,.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Yee, Richard K,,DMDCWEST]

Caroline,
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.

Regards,

Richard

I pass two hidden fields: username and keyName at the

value in it.  The username is passed but its value
turns out to be a null.

It is impossible for request.getRemoteUser(); in my
JSP returning a null.  (see code below) Before it
reaches request.getRemoteUser(); the user has already
been successfully logged in with a valid name.

[Yee, Richard K,,DMDCWEST]

Caroline,
Are you having problems with the username or the keyName hidden variable? If
it is the username, then I'd suspect that request.getRemoteUser() in your
JSP is returning null.

Richard

I did not mess up lowercase and uppercase of the
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:



<% String username = request.getRemoteUser();%>


View Articles



and an action mapping:


   


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
(

Access.findByProperty( this,property,value
)

);
list.setLegend( property,value );

return new ProcessResultBase( list );

   } // end execute

} // End FindEditorData

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction

[Caroline Jen]

I did not mess up lowercase and uppercase of the
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:



<% String username = request.getRemoteUser();%>


View Articles



and an action mapping:


   


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
(

Access.findByProperty( this,property,value
)

);
list.setLegend( property,value );

return new ProcessResultBase( list );

   } // end execute

} // End FindEditorData

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction

[Caroline Jen]

My code was shown in my original message.  I used two 
 tags to pass two hidden fields, one
is successfully passed while the other shows null.  By
the way, I do not use 'request' to retrieve the value
of the hidden field because my Java class is a
scaffold.ProcessAction type.  I simply use getXxx.

Let me show my code again:


<% String username = request.getRemoteUser();%>

Are you using the  or html:hidden attributes? I 
didn't see it in your email.
If you do, the values will be available in the request.

Re: PLEASE HELP: Exception handling

[Vic Cekvenich]

Say this in WEB.XML

java.lang.Exception
/error.jsp
 
Then this in error.jsp or what ever you consider friendly:
<%@ page isErrorPage ="true" %>
You are at a J2EE error page:

<%= exception.getMessage() %>
and then:

throw new Exception("Oops, I did it again");
Or if you want to localize.
There are many variations, but KISS will start you.

Re: Please Help!!! A Validation Rule Fail On A Second-Page Causes A Blank Page To Show Up

[Kam Lung Leung]

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.

RE: Please help: Cannot find message resources under key org.apache.struts.action. MESSAGE

[Rajat Pandit]

According to your struts config, the path for the res. File should be
something like this.
/WEB-INF/classes/ApplicationResources/properties.properties

The res file being named properties.properties which Is not wrong just
that it sounds funny. 
I guess you got my hint. So you will need to make osme changes. And I
guess RTFM!!
Take care and hope this helps!

Re: please help: ActionForms of same type but different name?

[Kirk Wylie]

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  instance of each of 
LoginFormA, and LoginFormB.

For each visible , you would have a form which, on submit, 
would populate the hidden LoginFormA or LoginFormB instance, setting a 
hidden value indicating which visible  was actually 
submitted, and then submit the HIDDEN  corresponding to the 
particular form bean you needed to use.

Would this pattern work for you?

Continued..

So there are two levels of distinction here - the first one being
between
LoginFormTypeA and LoginFormTypeB. But that is no big issue since
the actions that map to them are different.
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  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!

Re: please help: ActionForms of same type but different name?

[Sonam Belbase]

Continued..

So there are two levels of distinction here - the first one being
between
LoginFormTypeA and LoginFormTypeB. But that is no big issue since
the actions that map to them are different.

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  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!

Re: please help: ActionForms of same type but different name?

[Sonam Belbase]

Tim,

We do have the same form and the same action and more
specifically, we have the LoginFormTypeA processed by loginActionA
and LoginFormTypeB processed by loginActionB. Of the
5 login forms, three could be of type A, 2 could be of type B.

RE: please help: ActionForms of same type but different name?

[Chen, Gin]

The problem here is that with 5 login forms.. How would you know or even
care which of the 5 was used to submit?
Is it processed differently if I pick m of n versus x of n?
In any case sounds like what you really want is the same form and the same
action.
Ie..

I might have a bean such that it only contains one parameter.
(don't mind syntax as stupid outlook keeps trying to apply spelling and
grammer rules which I don't want to turn off cause I'm the worst
speller/grammulator)





This bean is mapped to the same action. (ex. /loginAction)

Then for my JSP :
//remember n is simulated ie. don't put n in end (duh) :)

 
  
  
 
  
 


Now your action is pretty simple.
Based on the formIteration value you know which of the n forms was used to
login.
Hope that helps.

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
 sections. User will specify at runtime
how many he/she wants. The  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.

Re: please help: ActionForms of same type but different name?

[Sonam Belbase]

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
 sections. User will specify at runtime
how many he/she wants. The  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.

RE: please help: ActionForms of same type but different name?

[Chen, Gin]

One approach, you can define as many form-beans as you want iteratations.
Ex:




.
.
.



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.

"LoginForm_2" in the second iteration, and so on.

In struts-config:



LoginForm extends ActionForm.

I understand that the attributes "name" and "type" have been deprecated
but I am trying to get the iteration to create and display a new
instance of the LoginForm, each with it's own name and properties. After
submit, the request processor seems to look for a formbean associated

property values are all null.

Anyone know how I can get it to look for the formBean with the unique

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 ***

RE: Please help with this error "???en_US.errors.required???"

[Daniel H. F. e Silva]

Hi Vivien,
 I think it depends on Struts version you are using. I use 1.1 and everything works 
fine.
Your  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.

Regards,
 Daniel.

RE: Please help with this error "???en_US.errors.required???"

[Chen, Vivien]

Thanks for your tips which gave me some idea what to look for. My web.xml is fine. The 
problem is I have the following in my struts-config.xml, which I copied/pasted from 
the strust-config.xml in the Struts tiles_documentation examples. Will my application, 
which uses tiles, breaks at some point if I don't include it as the comment states?

Hi Vivien,
  Sorry, but i did not make myself clear. Property you have to check existence in 
web.xml is
"application". It has same effect as "parameter" attribute of . So,
if you find it there (web.xml), remove it.
  Hope it helped you.

Regards,
 Daniel.

I checked my web.xml and did not see message-resources being defined there. Do you 
have any other idea where I might do wrong. I am really stuck with this problem now.

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.

Kind regards,

Hi Daniel,
do you use JSTL as well as struts taglibs?  I was wondering how you 
would configure multiple 'localization contexts' in web.xml for use by 
different JSTL taglibs.

And if so, how do you make one the default?

e.g.

  

  javax.servlet.jsp.jstl.fmt.localizationContext

Re: Please Help Me To Understand "forward"

[Ted Husted]

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:






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:






The menu.jsp is the main content page, but other pages are also used to 
create the final response.

-Ted.

I am studying the code in Artimus_1_1 to make sure

at the beginning of the application.  Please kindly
help me.  The index.jsp of the application contains
two lines:
code:
--
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

Does this redirect forward tells the browser to submit
a new request to the path with logical name "welcome"?
I then searched the config.xml file, 

code:
---


 
name="baseStyle" 
path="/article/assets/styles/base.css"/>

 
name="welcome"
path="/do/Menu"/>
 
name="cancel"
path="/do/Menu"
redirect="true"/>
 
name="done"
path="/do/Menu"/>
 ...


---

The path of the logical name "welcome" is "do/Menu"
(note it is upper case Menu).  The other place that
"do/Menu" appears in the config.xml is:

path="/MenuCreate"
name="menuForm"
   
type="org.apache.struts.scaffold.ProcessAction"
   
parameter="org.apache.artimus.article.MenuCreate">
   
name="success"
path="/do/Menu"/>

name="failure"
path=".article.Menu"/>


There is no Menu ActionServlet in the application.

There is a menu.jsp (note it is lower case menu) file
in the application. Does this application display
menu.jsp when it is first launched? Apparently, it
does. This menu.jsp is in the
artimus_1_1/WEB-INF/src/pages/article/content folder.
I am confused - does /do/Menu locate the menu.jsp 

1. in the /src/pages/article/content folder?
2. regardless upper or lower cases?

RE: PLEASE HELP with Exception in error.jsp with Tiles

[Richard Mixon]

Hue,

Thanks. That did help as it showed it had nothing to do with the error.jsp.
Turned out to be a real rookie mistake - a mispelled message key. I'm
embarrassed, to say the least - but very, very happy to be on my way again.

Hi Richard,

First things first - ditch 1.4.1 and get 1.4.2 - I've had endless unusual
problems with 1.4.1 - except the very latest release - but 1.4.2 seems
faster to me as well. Hmmm - lots to look through ... "msanger" - Microsoft
make you that mad, eh?

It looks to me like a further exception is being thrown in the error.jsp
(possibly relating to bean:message key="errorPage.heading" - is this line
correct?).

My advice would be to simplify the error.jsp significantly (i.e. start with
static content) and build it back gradually. I remember a post a while ago
about a gotcha in that when using tiles the error page appears after the
already committed content of the tiles - so you may need to consider this
too?

Good luck!

RE: Please Help With Simple Tiles Problem

[Terry Brick]

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 ;)

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:
" flush="true" />

Then in page.jsp you need to do two things the easy one is include form_wrapper.jsp:

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:


Now the definition can look like this:
 

 


 

 

 

I know it is messy - but it should work.

Thanks for your response David.  Correct me if I'm
wrong, but isn't this exactly what I had in my
example?  Maybe I'm just not grasping something...
It looks to me like I'm still having to add two
 blocks for each form I want to add.
Under your "form_page" definition you point to form1
-OR- form2. But in reality can't you only have one or
the other?  I have an struts action pointing to each
form so wouldn't I have to do something like...


 

 

 

 

 

 

 

 

 


So I would have an action pointing to "form_page1" and
an action pointing two "form_page2".  But I would have
to add two definitions to my tiles-config file for
each form.  It just seems redundant to me.

Sorry if I'm being dense, your patience is much

Re: Please Help With Simple Tiles Problem

[Terry Brick]

Ok, I've finally gotten this to work.  However, I
don't think it's the "right" solution and it's
certainly not one I'm happy with.  But maybe by
showing how I'm getting it to work, that will better
communicate to people what I'm trying SO HARD to do.

This works:




   



   


So this gives me...

  

  


The problem is that "form1.jsp" will not always be
"form1.jsp".  I want to be able to swap that for a
"form2.jsp", "form3.jsp", etc.  Using this method, I
would have to add TWO definitions into the
tile-defs.xml for each new form I wanted!  (form2,
form2a, form3, form3a, etc)
There must be a better way where I only have to add a
single definition for each new form.  Any ideas? 
Advice is much appreciated. Thanks.

Thanks.  I've seen that page and many other.  Believe, I feel stupid from seeing so

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.

Re: Please Help: ActionForm Re-Population

[Aaron Longwell]

Oops, spoke too soon.

You discussed 2 options:

1) All drop-down list data goes into session
2) "input" attribute for the update event goes back to "edit" Action 
instead of "edit" JSP

I went with #2 and that brings up a new issue. Doing that causes all of 
the current values for the fields to be lost (i.e. the user inputs a bad 
number format in a field they click submit and receive the JSP with 
a list of errors at the top) Because the process went through the "edit" 
action again, the Action re-queried the database and updated the 
ActionForm with database values, overwriting all the user's values 
(including ones that were correctly edited and contained no errors).

To avoid this I have to insert code in the "edit" Action to check for a 
populated ActionForm before querying the database. This feels a little 
messy.

Of course I could use the session solution (#1), but I like to avoid 
using sessions unless absolutely necessary. In addition, these drop 
downs could have 100's of items in them, I'd like to keep big chunks of 
data like that in the request.

So the alternative, I guess, is to have another action that NEVER 
queries the database, but just prepares a blank form. I actually already 
have one of these... it's my "create" action.

This appears to be the best practice in this situation anyone else 
have any feedback?

Thanks again,
Aaron

After the RequestProcessor has populated your action form, validate is
called. This happens before your action is called.

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
action.

Dirk,

Thank you, thank you thank you thank you.

It was almost too easy. I just changed the input attribute to point to 
my action instead of my JSP and the problem is solved.

After the RequestProcessor has populated your action form, validate is
called. This happens before your action is called.

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
action.

Then you must be using an old pre-Struts version of Tiles.  Sorry but I 
can't help you there.

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

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:

Re: Please help a Tiles problem

[Vernon]

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?

Re: Please help no getter method nightmare

I partially solved this error writing


but why does this work only with this deprecated solution???

Thanks in advance,

Hi all,
I've a big problem in my project:
I can't add any getter method in any new form since on every jsp form 
i get back message.

javax.servlet.jsp.JspException: No getter method for property fooProp 
of bean org.apache.struts.taglib.html.BEAN

I tryed with several foms (also the famous FooForm), but the result is 
always the same.
I attach my struts-config.xml file.

The thing I really can't understand is that all forms perfectly work 
except the one defined in /chooseAgenda action or those created from 
scratch and inserted (no matter the position).

Please I really need help !!

enrollDate should be a String in your formBean. Are you sure you
aren't trying setting enrollDate as a Date type in your form bean?

I cc'd Samir as well, since I think he is having similar problems. I
think it's nice and clean to deal with Dates in forms this way:

1) Have a form bean with all Strings representing your jsp form. So
something like birthDate would be set up as a String.

2) Have a business bean with the correct data types. For example..
java.util.Date birthDate, double someNumber, etc.

3) When you submit your jsp page to your action you can take care of
the conversion of the FormBean(all Strings) to the correct data types
and populate your business bean (usually called a DTO or ValueObject).
Similarly, when going the other direction you can take a business bean
and convert the Date fields into Strings (with the format you like)
and populate your FormBean and display that to the user.

As far as doing the conversion I usually take care of that outside of
the Action and use the BeanUtils.copyProperties(..) but you can also
just create your own helper class to do the conversions for you if you
like.

Thanks for your help! I corrected my mistake by using the String equals() method, and

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 
see if something miraculously appears.  Debuggers are not very clever at 
finding the real problems, like this one, if this is right.

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.

RE: Please help decide a religious discussion

[Jeff_Mychasiw]

We have done alot of this and have tried many things.

In our case, If possible all of our static lists (provinces ect) are loaded
at application startup and put into application scope.
The plug-in's are great for this but there are many other ways.
If the  lists are User specific, they go into session.

And as a last resort if they are required at request time, they are
absolutely put  in the LoadAction for that page.
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.

Well if the Action is needed to populate the drop-downs (these values being
in request scope I presume?) then after the form is submitted and
validation
has failed, you will need to reload these values. If you are loading the
values in an action you will need to go through that action. (The other
alternative is to store the info in session scope, but that creates the
potential problem of knowing when to get rid of it)
Perhaps the idea might be to have an action whose sole responsibility is to
populate the drop-downs and instead of forwarding directly to the view, you
go through this one first and it forwards you to the view after populating
the drop-downs.

The Action class...but the action should be asking a helper object for a
list of whatever goes in your drop down.  It shouldn't know about the
database directly.  So you might have in your action.execute():

List list = StateHelper.getStateList();
// put list in your form

RE: Please help decide a religious discussion

Yep. Eventually the session times out, but in the meantime a wandering user
could theoretically accumulate a lot of garbage in their session.

(And it just occurs to me that a malicious user could exploit it to fill up
the memory with junk)

If however one follows the recomendations to keep the size of stuff in the
session small (ie: dont be caching several megs of stuff!) then it probably
still wouldn't amount to enough to be a serious problem in most cases -
except on those very high traffic sites (ie: amazon.com).  As a matter of
principle however I don't particularly like have obsolete objects lying
round when they should be made eligible for the GC - though of course I dont
let this principle stop me from using the session ;->

Yes, but what happens if the user 'wanders off' in the meantime (ie: through

Drop down list data should be cached, if data is not updated dynamicly.
With Struts, if you are using Tiles, you can created a drop down list
components get the list data from cache via controller class.

RE: Please help decide a religious discussion

[Andrew Hill]

Well if the Action is needed to populate the drop-downs (these values being
in request scope I presume?) then after the form is submitted and validation
has failed, you will need to reload these values. If you are loading the
values in an action you will need to go through that action. (The other
alternative is to store the info in session scope, but that creates the
potential problem of knowing when to get rid of it)
Perhaps the idea might be to have an action whose sole responsibility is to
populate the drop-downs and instead of forwarding directly to the view, you
go through this one first and it forwards you to the view after populating
the drop-downs.

If I do that, will validation always go to the action class, even when it
fails?

Sounds like you need to define the action and not the jsp as your input in
struts-config.

That is what we are doing now. It goes through a controller to the
database, but we are using the validator and when an error occurs, the form
does not go to the Action class and the helper methods are not called and
as a result, the drop downs are empty.

The Action class...but the action should be asking a helper object for a
list of whatever goes in your drop down.  It shouldn't know about the
database directly.  So you might have in your action.execute():

List list = StateHelper.getStateList();
// put list in your form

RE: Please help decide a religious discussion

[Stephen . Chambers]

No, it is a little different.

The user calls Page-A
   ---> form-A is instantiated
 --->action-A is run and the execute method is called, prepopulating the
drop downs
--> the user does stuff and submits
 --> Validation of form-A fails and does not go to Action-A
--> Page-A re-displayed, but with empty drop downs

I hope this helps.

Wait a minute.  Is this the current setup?


  Action-A (does stuff, preps form-B for page-B)
--> Forward to Page-B
  -->  User does stuff and submits
 --> Validation of form-B fails
   --> Page-B re-displayed but with empty s?

Hard to believe!  I say so because the population of the selects is done by
the business logic invoked by Action-A which is no longer in the picture.

All that your validate should be doing is *test* the data and set
ActionErrors if necessary.  Make sure you aren't wiping out your
collections.
