    Jboss AS 7 remote EJB 3.1 ClassCastException from 2 different ears

    Andrea D'Angelo Newbie

      Hi to all i am studyng ejb 3.1 and jboss as 7

      I would like to understand haw call a remote ejb from another ear 

      like in this example:

      i have 2 ears

      like in this example below

       

      in the same app server i have 2 ear :

       

          myapp.ear

              |

              |

              |

             +------------------- myappEJB.jar

                                             |

                                             |                             @Stateless

                                             + it.test.MyEjb        public class MyEjb implements MyEjbRemote

                                             |

                                             |                                        @Remote

                                             + it.test.MyEjbRemote        public interface MyEjbRemote {

       

       

       

      test.ear

        |

        |

        |  

      +------ testweb.war

                      |

                      |

                     + --------------------- WEB-INF

                                                 |

                                                 |

                                                + classes

                                                        |

                                                        |

                                                        + it.test.MyEjbRemote (is the copy of the interface)

                                                        |

                                                        |

                                                        + it.test.servlet TestServlet

                                                                  String url = "java:global/myapp/myappEJB/MyEjb!it.test.ejb.MyEjbRemote";

                                                                  Context ctx = new InitialContext();

                                                                  MyEjbRemote remote = (MyEjbRemote) ctx.lookup(url);

       

      i always receive the same error :

       

      java.lang.ClassCastException: it.test.ejb.MyEjbRemote$$$view1 cannot be cast to it.test.ejb.MyEjbRemote

       

      My question is haw i could call the remote EJB ?

      And Haw i could call the EJB if the ejb was installed in another machine ?

      With previous versions of jboss i used the prefix jnp:// etc

      what change now ?

       

      thank you very much Andrea
