First up all I like to thanks Rick since you have reply. Basically I am new
here..
I tried to give all the details-
Actually, I am trying to implement the common ActionForm which holds the
value of the JSP/HTML fields. So then I did not need to implement the
ActionForm for all my jsps. This ActionForm will pass it to common Action
Class that will be responsible to handle all the events. For of now I need
this much functionality.
To accomplish this I found out in the struts docs that you can use 'MAP
BACKED ACTIONFORM' so then I have tried that as follows-
//Common ActionForm-
package com.web.controller;
import java.util.Map;
import java.util.HashMap;
import java.util.Iterator;
import org.apache.struts.action.ActionForm;
public class GenForm extends ActionForm
{
private final Map values = new HashMap();
public void GenForm()
{
System.out.println("GenForm Constructor");
}
public void setValue(String key, Object value)
{
System.out.println("Keys=" + key + " ;value=" + value);
values.put(key, value);
}
public Object getValue(String key) {
return values.get(key);
}
}
//Common Action Class
package com.web.controller;
import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.lang.reflect.Modifier;
import java.util.Enumeration;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
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.config.impl.ModuleConfigImpl;
import com.web.controller.GenForm;
public class CommonEventHandler extends Action
{
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception
{
System.out.println("reached here");
if (form == null)
{
System.out.println("Action Form is null");
}
else
{
System.out.println("Action Form is Filled");
}
System.out.println(((GenForm)form).getValue("username"));
return null;
}
//struts-config Entries
<form-beans>
<!-- Generic form bean -->
<form-bean name="GenForm"
type="com.web.controller.GenForm"/>
</form-beans>
<action-mappings>
<action path="/button"
type="com.web.controller.CommonEventHandler"
name="GenForm"
scope="request"
validate="false"
input="login.jsp">
<forward name="failure" path="/mainMenu.jsp"/>
<forward name="success" path="/jsps/t.jsp"/>
</action>
//Login JSP
<HTML>
<HEAD>
<TITLE>Login Page</TITLE>
</HEAD>
<BODY>
Login
<BR>
<FORM METHOD=POST ACTION="button">
Username:<INPUT TYPE="text" NAME="username">
Password:<INPUT TYPE="text" NAME="password">
<INPUT TYPE="submit" value="SignIn">
</FORM>
</BODY>
</HTML>
Now, for of now I have not coded forward and all.. If in the Action Class, I
ll get fields value for username and password then I can go ahead. Control
has reached upto CommonEventHandler Action class but ActionForm has not
filled up with the username and password?
So, now my questions are -
1. Is am I on a right track???
2. Is this possible in Struts Framework what I need?
3. Is there any other way around or any other framwork which I can use to
accomplish my requirement?
Kindly get back to me If you have any further queries. Expecting some one
will help me in this struts world.
Thanks and Regards,
Vishal Agashivala

Why don't you explain what you need help with? Like what you have tried
so far? What you want to accomplish? What isn't working? Anything would
be helpful to give us some direction. My first question would be why do
you want to back your form by a Map?
