RE: Map Backed Action Form
Vishal, First of all. Quit whining. We are not here to just answer YOUR questions. You would get better responses if you read http://www.catb.org/~esr/faqs/smart-questions.html, read the FAQs, and did a search in the archives. Have you read the documentation? There is how-to guide there that describes what to do. http://localhost/struts-docs/faqs/indexedprops.html You could also search the archives as this question is covered often. If you are using a mapped backed form just to avoid writing ActionForm classes, then you should look at DynaForms. You will find that they are better for this purpose. I personally think you are going down the wrong path because you will not be able to use the validation feature of the Validator very easily with your approach.

In your Action, CommonEventHandler , you'll decide, based on
tha value of a
certain field, which should be present in all your jsp and
let's call it op,
what you should do . So for example
in your CommonEventHandler you'll have
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception
{
GenForm gform = (GenForm)form;
String op = (String)gform.getValue("op");
if(op.equals("Signin")){
String login = (String)gform.getValue("login");
String password = (String)gform.getValue("password");
//do your stuff here
}else if(op.equals("Signout")){
..
}
}
So based on your op parameter you'll know what you have in your
GenForm each
time you're executing CommonEventHandler.
That's a way to do it, but you could also have your
CommonEventHandler extends
DispatchAction and implement this in a more clean way

RE: Map Backed Action Form
Hi
I have checked the URL which you have suggested but there I did not find the
example of accessing a field value of form in Action class. It only gives to
use it JSP via .
Can you give me some more information on the same?
Thanks and Regards,

RE: Map Backed Action Form
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
//Login JSP
Login Page
Login
Username:
Password:
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?

Subject: Map backed action form
Hello,
I have a problem with my map backed form.
When I try to validate the form, when I try to retrieve value it throws a
null pointer exception, as if the map was null.
I am successful going through my jsp and populating the bean, so i am not
sure what is going on.
What might be the problem?
form:
private Map properties;
public Map getProperties() {
return this.properties;
}
/** Setter for property properties.
* @param properties New value of property properties.
*
*/
public void setProperties(Map properties) {
this.properties = properties;
}
public void setValue(String key, Object value) {
properties.put(key, value);
}
