[jboss-user] [JBoss Portal] - IPC problem

[senthilkumar.devan]

Hi..
Can anyone help me in IPC problem. I have portlet A and portlet B. I am trying to trigger from portlet A but there is no output and no exceptions. The problem is request havent went for processaction method in porltet B.

Steps i have followed is...
1. I have created a war file
war files contains web-inf and meta-inf.

in meta-inf i have jboss-service.xml
Inside this xml i have following code 

<?xml version="1.0" encoding="UTF-8"?>

   <mbean
         code="org.jboss.portal.core.event.PortalEventListenerServiceImpl"
         name="portal:service=ListenerService,type=ipc_listener"
         xmbean-dd=""
         xmbean-code="org.jboss.portal.common.system.JBossServiceModelMBean">
      
      <depends
            optional-attribute-name="Registry"
            proxy-type="attribute">portal:service=ListenerRegistry
      ipc_listener
      org.jboss.portlet.hello.HelloWorldPortletB$Listener
   


under web-inf i have 
helloworld-object.xml
<?xml version="1.0" encoding="UTF-8"?>

	
		<parent-ref>default</parent-ref>
		<if-exists>overwrite</if-exists>
		
			<page-name>IPC</page-name>
			
				<window-name>
					HelloWorldPortletAWindow
				</window-name>
				<instance-ref>
					HelloWorldPortletAInstance
				</instance-ref>
				
				center
				1
			
			
				<window-name>
					HelloWorldPortletBWindow
				</window-name>
				<instance-ref>
					HelloWorldPortletBInstance
				</instance-ref>
				ipc_listener
				left
				1
			
		
	
	

Then i have portlet A class 
package org.jboss.portlet.hello;


import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.PortletSecurityException;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import java.io.IOException;
import java.io.PrintWriter;

/**

public class HelloWorldPortletA extends GenericPortlet
{
   protected void doView(RenderRequest request, RenderResponse response) throws PortletException, PortletSecurityException, IOException
   {
      response.setContentType("text/html");
      PrintWriter writer = response.getWriter();
      writer.println("<form action=\"" + response.createActionURL() + "\" method=\"post\">");
      writer.println("<select name=\"color\">");
      writer.println("blue");
      writer.println("red");
      writer.println("black");
      writer.println("");
      writer.println("<input type=\"submit\"/>");
      writer.println("");
      writer.close();
   }
   
   public void processAction(ActionRequest request, ActionResponse response) throws PortletException
   , PortletSecurityException, IOException
      {
	   System.out.println("Entere process action");
       System.out.println("The parameter names are"+request.getParameter("submit"));
	   String requestBtn = (String) request.getParameter("submit");
	   System.out.println("The request btnis"+requestBtn);
       response.setRenderParameter("submit", requestBtn);
       	   
      }
}

Then i have portlet B class
