    reflection use on home/proxy

    sebastien Newbie

      Hello !

      I'm trying to perform some common code to invoke method on home computed with the reflection API (code without try/catch):

      Object homeref = initial.lookup(compName);
      Class xClass = homeref.getClass();
      InvocationHandler invctHandler = Proxy.getInvocationHandler(homeref);
      Method findByPrimaryKey = xClass.getMethod("findByPrimaryKey", new Class[] {scopedAidClass});
      object = invctHandler.invoke(homeref, findByPrimaryKey, new Object[] {scopedAid});

      at runtime I get the following exception:

      15:32:52,378 INFO [STDOUT] homeref class is $Proxy134
      15:32:52,388 INFO [STDOUT] Sucessfull xClass.getMethod findByPrimaryKey

      I have define correctly the ejb-external-ref to be able to use the bean on which I'm invoking the home.

      I know somewhere the code has to be downloaded into the proxy. So I tried to narrow the homeref with the PRO though in local:
      Object homestub = (Object)PortableRemoteObject.narrow(homeref, thisHomeClass);
      without any effect, still getting the same proxy and getting the same exception at runtime.

      Thank you for any help.

      seb.
