    JBoss 4.0.4.GA HomeHandle NoInitialContext

    Marcelo Giorgi Newbie

      We use some kind of cache of HomeHandle objects in a remote JVM that obtains the Home object using the following code:

      Hashtable environment = new Hashtable();

      environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
      environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
      environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");
      InitialContext context;
      try {
      context = new InitialContext(environment);
      Object obj = context.lookup("ejb/EJBTest"); //ejb-name
      EJBHome home = (EJBHome)PortableRemoteObject.narrow(obj,EJBTestHome.class); // (1)

      ...

      } catch (NamingException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
      }

      After (1) we store the HomeHandle of the EJBHome object in that way we can use it in a latter time saving the overhead of the lookup opeartion. BUT we get the following error when we invoke getEJBHome() on the stored HomeHandle object.

      Caused by: java.rmi.ServerException: Could not get EJBHome; nested exception is:
      javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

      Anyone know why it is not working ? Anyone knows if there is a problem using a remote client (that lives outside de Jboss JVM) that stores/retrieve the HomeHandle of an EJBHome object that resides in the JBoss JVM.
