IPC problem
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

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
