form bean doesn't come into picture

I'm writing a simple application using struts & trying to deploy it on Tomcat Server.

First page of an application just accepts two values(userName and password) from user & passes onto next page via formbean, which then gets displayed on that page.

But my bean never gets populated i.e. no reset(), validate() and setter method gets invoked. THE request just gets forwarded to next page and no value appears there.

Please find below the struts-config.xml file I'm using:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>

<form-beans>
<form-bean name="loginForm" type="forms.LoginForm">
</form-bean>
</form-beans>

<action-mappings>
<action name="loginForm" path="/login" scope="session" type="action.LoginAction">
<forward name="success" path="/login.jsp">
</forward>
</action>
</action-mappings>


<message-resources parameter="resource.ApplicationResources"/>

</struts-config>

I have crosschecked the spelling of class names. My formbean also extends ActionForm.

What can be the possible causes, which prevents the bean to come into picture. Any help would be highly appreciated.

Thanks.

need to see your form, action and jsp that uses this form for presentation.
Please use code tags

I agree...I cannot see anything wrong in your mappings but seeing at least your jsp would help. I take it that you are showing the initial page directly and not using an action.

You are right, Brent. Thanks for your reply.
I'm directly invoking my first JSP without action class.
Below are the Action class, Form bean and jsp I'm using:

Index.jsp(which I'm accessing directly as first page)

-------------------------------------------

LoginForm.java (The form bean)

-------------------------

LoginAction.java

package action;
 
import javax.servlet.http.*;
import javax.servlet.*;
import org.apache.struts.action.*;
import forms.*;
 
import forms.LoginForm;
 
/**
 * @version 1.0
 * @author
 */
public class LoginAction extends Action 
{
 
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception 
{

ActionErrors errors = new ActionErrors();
ActionForward forward = new ActionForward();

LoginForm loginForm = (LoginForm) form;
 
try
{
System.out.println(loginForm.getUserName());

}
catch (Exception e) 
{
 
// Report the error using the appropriate name and ID.
errors.add("name", new ActionError("id"));
 
}
 
// If a message is required, save the specified key(s)
// into the request for use by the <struts:errors> tag.
 
if (!errors.isEmpty()) 
{
saveErrors(request, errors);
 
// Forward control to the appropriate 'failure' URI (change name as desired)
forward = mapping.findForward("failure");
 
}
else
{
 
// Forward control to the appropriate 'success' URI (change name as desired)
forward = mapping.findForward("success"); 
}
 
// Finish with
return (forward);
 
}
}

------------------------------------------

Login.jsp (The next page which should display userName entered by user)

Thanks...

Would you please create a default value for userName in the form. that way you can see if the form is being forund in the indicated scope or it is being created in the useBean tag.

It might just be a matter of the case on your method...change setUSerName to setUserName.

You are just perfect, Brent.
That was really a mistake.
Thanks a lot, both of you.
