I am trying to implement wsrp between weblogic and websphere where weblogic 10.3.4 is the producer and websphere 6.1 is the consumer. I have created weblogic portlet which displays the logged in user details like remote user, authentication type princpal name.
When i consume the portlet through websphere portal admin console, getting the remote user name and authentication type as FORM but the principal name is returning null.

Here is my producer portlet code:

package com.demo.portal.portlet.supersnoop;


import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

* SuperSnoopPortlet
public class SuperSnoopPortlet extends GenericPortlet implements Version{

* @see javax.portlet.GenericPortlet#doView(RenderRequest, RenderResponse)
protected void doView(RenderRequest req, RenderResponse resp) throws PortletException, IOException {

PrintWriter out = new PrintWriter(resp.getWriter());

String remoteUser = req.getRemoteUser();
String authentication = req.getAuthType();
String principalName = (request.getUserPrincipal() == null)
? null
: request.getUserPrincipal().getName();

out.println("<h3>User Attributes</h3>");

out.println(authentication );
out.println(principalName );


I couldn't find anything on web, Is there a way to fix this issue? Can some one help me with this ?
