How to call a non JBoss Application server (WebLogic) via IIOP using CNCtxFactory from JBoss EAP 5.0.1?

Issue

• Cannot retrieve appropriate EJBHome for EJB deployed on WebLogic server.
• Context.INITIAL_CONTEXT_FACTORY=com.sun.jndi.cosnaming.CNCtxFactory
• Context.PROVIDER_URL=iiop://WEBLOGIC_HOST:7001
• All other InitialContext properties unmodified

• Here is how we access the EJB

      Context context = new.InitialContext(environment)
      Object beanref = context.lookup(com.jboss.examples.ejb.Hello);
      Object beantmp=PortableObjectRemote.narrow(beanref, com.jboss.examples.ejb.HelloHome.class)
      my-bean-nameHome beanHome = (HelloHome)beantmp;
      my-bean-name NewBean = beanHome.create();
  

• The EJB is deployed on WebLogic using:

     <weblogic-enterprise-bean>
         <ejb-name>HelloBean</ejb-name> 
        <stateless-session-descriptor>
        <pool>
          <initial-beans-in-free-pool>5</initial-beans-in-free-pool> 
         </pool>
       <stateless-clustering>
           <stateless-bean-is-clusterable>true</stateless-bean-is-clusterable> 
       </stateless-clustering>
     </stateless-session-descriptor>
      <enable-call-by-reference>true</enable-call-by-reference> 
     <jndi-name>Hello/jndi-name> 
     </weblogic-enterprise-bean>
     <weblogic-compatibility>
       <entity-always-uses-transaction>true</entity-always-uses-transaction> 
     </weblogic-compatibility>
  

• The IIOP stubs are compiled for the EJB on WebLogic using:

     <target name="appc">
         <java classname="weblogic.appc" fork="yes" failonerror="yes"
               classpathref="compile.path">
               <arg value="-iiop" />
               <arg value="-basicClientJar" />
               <arg value="${dest.dir}/${ant.project.name}.jar" />
          </java>
     </target>
  

• We receive a non-null response with an embedded IOR from our "lookup" call and an object of type my-bean-nameHome_stub after our "narrow" call.

• There is a ClassCastException during the "create" method as follows:

  java.lang.ClassCastException: org.jacorb.orb.Reference cannot be cast to com.abc.my-bean-name 
        at com.com.abc.my-bean-nameHome_Stub.create(Unknown Source)
