The following code works for as a standalone client.

    Properties props = new Properties();
    props.put("java.naming.factory.initial", "com.ibm.websphere.naming.WsnInitialContextFactory");
    props.put("java.naming.provider.url", "corbaloc::hostxxx:1031");

    System.out.println();
    System.out.println("Running IIOP test...");
    Context intCtx = new InitialContext(props);
    System.out.println("Found IIOP InitialContext");
   
    Object obj = intCtx.lookup( "cell/clusters/Services_Cluster/ejb/FacadeBean") ;
    System.out.println("Context Lookup found ");
    FacadeBeanHome remote = (FacadeBeanHome) javax.rmi.PortableRemoteObject.narrow(obj, FacadeBeanHome.class);
    System.out.println("Found IIOP EJB Remote");
    FacadeBean bean= (FacadeBean) remote.create();

However, when I used the JNDI context as above in my war project and deploy in Jboss AS 7, I've got an error as below:
