    PortableRemoteObject.narrow - ClassCastException

    elaineqs Newbie


      I'm using Jboss 3.2.2RC4. I have two enterprise application. A.ear has a servlet and B.ear has some EJBs and JSPs. My servlet code (in A.ear) is similar to (UserEJB is in B.ear):

      // inside doGet .... //MainFormBean is a JavaBean
      jndiContext = new InitialContext();
      Object ref = jndiContext.lookup("UserEJB");
      UserEJBHome home = (UserEJBHome) PortableRemoteObject.narrow (ref,UserEJBHome.class);
      UserEJB user = home.create();
      MainFormBean response = (MainFormBean) user.addUser("test");

      I need to deploy A.ear separetely (before B.ear). All works fine if i deploy A.ear and B.ear at the same time, but it fails (PortableRemoteObject.narrow - ClassCastException) if i try to undeploy and redeploy B.ear without to do the same with A.ear (servlet continues running).

      My questions are: After call the EJB, servlet maintains some information about it? Should i close (destroy) something after method invocation? Why do i receive that exception?

      The exception occurs at jndiContext.lookup("UserEJB"). After i redeploy B.ear, ref is not an instance of UserEJBHome, but i can not discover which type it is. Please, help me!!

      Thanks in advance!
