    JBossIDE-Tutorial problem.

    Kent Zhou Newbie

      I followed JBossIDE-Tutorial.pdf to create the fibo application. Everything is okay now.

      When I try to run this app, it is okay, index.html come out.

      But when I sibmit the form, it report error as :

      type Exception report
      message
      description The server encountered an internal error () that prevented it from fulfilling this request.
      exception

      After debuging, I found this error is caused by casting:

      home = (FiboHome) PortableRemoteObject.narrow(ref, FiboHome.class);

      The EJB FiboEJB already is there.

      What's the wrong with this jboss application?

          Hi: I'm certainly not an expert, but had similar problems. When you deploy the application, does is say:

          Bound EJB Home 'Fibo' to jndi 'ejb/Fibo'

          in the log? HTH.

            Remove the FiboEJB-clint.jar from FiboWeb.war when do the Packaging Configurations.

              After removing FiboEJB-client.jar form FiboWeb.war, I still got the error as below:

                After deploying the app, the info as

                ejb/Fibo already there, why servlet can not reference it in following code?
                Object ref = context.lookup("java:/comp/env/ejb/Fibo");

                OR

                Object ref = context.lookup("ejb/Fibo");
