    java.lang.reflect.UndeclaredThrowableException

    Tsuki Kawahara Newbie

      Hello all,

      I've been getting java.lang.reflect.UndeclaredThrowableException from my client class. This is the part of my code:

      Object obj = ctx.lookup ("DataLoader");
      DataLoaderHome home = (DataLoaderHome)PortableRemoteObject.narrow (obj,DataLoaderHome.class);
      item = home.create ();
      if (item!=null) {
      ValueList vl = item.getValueList ("Select * from ComputerQuiz", "java:/comp/env/jdbc/ItemBankSource");

      This very last line issues the error. The ValueList is basically ArrayList having a little more functionalities. When I call some test methods from the bean class (item), it was successful, so I am wondering if the problem comes from the communication between the server side and client side when sending certain objects such as ArrayList.

      Any suggestion would be appreciated.

      Thank you!

            Do you get warnings from the verifier when you deploy your bean?

              I dont know if this helps, but i got the same exception when i was migrating from 3.0.4 to 3.2.1. In my case, the error was because i was using a Stateless Session Bean configuration whose "invoker-proxy-binding-name" element was no longer valid in 3.2.1.
              when i checked the configurations my error was resolved

                Juha-
                No, I don't get any warings or errors for this when I deploy the bean. It is a runtime exception.

                raghu-
                I believe the invoker-proxy-binding-name you mentioned is specified in standardjboss.xml in server/conf and I use the default setting. Could you tell me how you change it? I use the version 3.2.1, too.

                  hi
                  if you are using the default configurations then you should not have any problems.
                  in my case i was using the jboss.xml file that i had created for 3.0.4 and when i deployed on 3.2.1 those settings for container configuration were not valid.
                  are you by any chance trying to migrate to 3.2.1 from an earlier version ?
