    Everything appears to work until I get to the last line and then get the stack trace that follows.

    Properties env = new Properties();
    env.put(Context.INITIAL_CONTEXT_FACTORY, “org.jnp.interfaces.NamingContextFactory”);
    env.put(Context.URL_PKG_PREFIXES, “org.jboss.naming:org.jnp.interfaces”);
    Context ctx = new InitialContext();
    Object o = ctx.lookup(“ejb/com/spcs/intranet/calculationAppeals/business/ejb/CalculationAppealsManagerBean”);
    CalculationAppealsManagerHome home = (CalculationAppealsManagerHome) PortableRemoteObject.narrow(o,CalculationAppealsManagerHome.class);

    Stack trace from ProtableRemoteObject.narrow:

    brucesanders63 ,

    I am afraid this is not a MyEclipse problem.

    I suggest you cross post to EJB forums or to development forums like http://www.coderanch.com for better support.

    Sorry for inconvenience.
