We are basically migrating from JBoss 5 to Jboss 6.1.  We have EJB 1.2 packed in our ear file and able to fix all the migration error and the application works fine.  Along with this, we do have a remote client application calling the ejbs packed in the ear  also.  I am stuck in that point now

Please find the code snippet

client code "...............................................................

logger.info("DefaultJDBCFacility1 get else  1111 ...");

         final Hashtable jndiProperties = new Hashtable();

         jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

         ctx = new InitialContext(jndiProperties);

         logger.info("DefaultJDBCFacility1 get else  2222...");

     String homeClassName = "org.ts.tris.util.client.service.ClientServiceHome";

     String jndiName = "ejb:TrisApp/TrisEJB/ClientService!org.ts.tris.util.client.service.ClientServiceHome";

       Object obj = ctx.lookup(jndiName);

      logger.info("DefaultJDBCFacility1 ... lookup completed...");

      logger.info("DefaultJDBCFacility1 ... next to lookup Portable class.."+PortableRemoteObject.narrow(obj,ClientServiceHome.class).getClass().getName());

      logger.info("DefaultJDBCFacility1 ... next to lookup Portable class.."+PortableRemoteObject.narrow(obj,ClientServiceHome.class).getClass().getInterfaces().getClass().getName());

      ClientServiceHome home = (ClientServiceHome) PortableRemoteObject.narrow(obj,ClientServiceHome.class);

      //ClientServiceHome home = (ClientServiceHome)obj;

      logger.info("DefaultJDBCFacility1 ... Portableable object completed");

      ClientService cs = (ClientService) home.create();

      logger.info("DefaultJDBCFacility1 ... create () complete ..." );

.........................................................................

ClientServiceHome is home inteface packed in the ear and runs the JBoss 6.1 app server.

The above code is aclient code which should get the home object. 

I am stuck while getting home object for ClientServiceHome.  ie in this line

................................

ClientServiceHome home = (ClientServiceHome) PortableRemoteObject.narrow(obj,ClientServiceHome.class);

................................................

It throws the following error
