    Corba

    ollka k Newbie

      Hi,

      I'm trying to find answer on using ejb3 with corba.

      With ejb2.1 it works fine, i set up iiop invoker in jboss.xml and my bean register at corba naming service.

      But i cannot find any possibility to do it with ejb3.

      Please, give me some links or advices to work woth ejb3 and corba.

      Thanks.

          To make a bean available over iiop use:

          @RemoteBinding(factory=org.jboss.ejb3.iiop.IORFactory.class)

            Thanks for your answer.

            And where I can find org.jboss.ejb3.iiop.IORFactory.class?
            I have tried almost all of jboss libs but there is no such class...

                And what name component should i use to resolve my bean?

                with ejb2 in deploying log i could see iiop and jndi name
                [Home IOR for MyBean bound to ejb/MyBean in JNP naming service
                Home IOR for MyBean bound to iiop/ejb/MyBean in CORBA naming service]
                , but now i can see nothing.

                I know jndi names, to that it binds automaticly, but what iiop name?

                  And should my Remote interface implements java.rmi.Remote?

                  When i try to use REmoteBinding in Bean Metadata, i have following:

                  When i use it before my remote interface, i have not such exception, so i think it doesn't work in that way...

                  • 6. Re: Corba
                    Carlo de Wolf Master

                    The JNDI names and Corba Naming names are equal.

                    So: HomedStatelessBean/home or MyStatelessBean/remote

                      What about exception?

                      When i try to use same name, i have org.omg.CosNaming.NamingContextPackage.NotFound exception.

                      I tryed to use RemoteBinding before remote interface and before bean.
                      In first case i have no exceptions while deploying, but nothing happens when i try to resolve by bean (i have NotFound exception)

                      In the second case i have exception, listed in my previos post, so i think, something doesn't work and it doesn't boud to corba naming service, or smth else happens, but result is the same - i have NotFount exception on my client.

                      • 8. Re: Corba
                        Carlo de Wolf Master

                        The bean must comply to EJB 2.1 API, so the Remote interface is mandatory. In JBoss the home interface is optional.

                        To lookup the bean I use the following properties:

                        Properties props = new Properties();
                         props.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
                         props.put("java.naming.provider.url", "corbaloc::localhost:3528/NameService");
                         props.put("java.naming.factory.object", "org.jboss.tm.iiop.client.IIOPClientUserTransactionObjectFactory");
                         props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming.client:org.jnp.interfaces");

                          Maybe i don't understand something...

                          Look
                          example of myBean
                          I have
                          @Remote
                          public interface MyBeanRemote extends java.rmi.Remote {...}

                          @Stateless
                          @Remote({MyBeanRemote.class})
                          @RemoteBinding(factory=org.jboss.ejb3.iiop.IORFactory.class)
                          public class MyBean implements MyBeanRemote {...}

                          When i deploy this - i have exception listed before (org.omg.PortableServer.POAPackage.AdapterAlreadyExists: IDL:omg.org/PortableServer/POA/AdapterAlreadyExists:1.0) (but bean is deployed)
                          And when i try to resolve bean from client, using your properties, i have NotFound exception.

                          If i try to move @REmoteBinding to MyBeanRemote interface, i have no exceptions but still have NotFound exception.

                            As i understand, my exception is a result of "double" binding to the same name. I don't know, why it happens, but it occurs only when i redeploy my ejbs.

                            If i restart whole server, i have another exception:
                            java.lang.ClassCastException

                                  Problem solved by patching file IORFactory (in jboss-ejb3.jar)
                                  Method createProxy make return CORBA.Object, don't narrow to EJBObject
