    Mogration from JBoss 4 to 7 --> problem with @RemoteBinding/@LocalBinding

    Stefan Schulz Newbie

      Hello.

       

      We are trying to migrate from JBoss 4.3.0.GA to JBoss 7.2.0.Final. In our session beans, we use annotations as '@RemoteBinding' and '@LocalBinding' like this:

       

      --------------------------------------------------------------->snip

      ...

      import org.jboss.annotation.ejb.LocalBinding;

      import org.jboss.annotation.ejb.RemoteBinding;

      ...

       

       

      @Stateless(name = "UserDAO")

      @Remote(UserDAORemote.class)

      @RemoteBinding(jndiBinding = "xyz/remote/UserDAO")

      @LocalBinding(jndiBinding = "xyz/UserDAO")

      public class UserDAOBean extends AbstractGenericDAO implements UserDAO {

      ...

      }

      ---------------------------------------------------------------<snap

       

      These annos come from the jar 'jboss-annotations-ejb3-4.3.0.GA.EAP'. We need this annotations in order to use our beans in JBoss 4. When i try to build an ear containing session beans like the one described above in an ejb module and deploy it to JBoss 7, i get the following error on start up:

      If i just copy+paste a bean like the one above and remove the lines with the pointed out annotations, it works fine in JBoss 7. That means, that JBoss 7 does not need those annotations, but nevertheless fails on deployment if i deploy beans containing them. As the error message i get talks about a default, my idea is to just implement something like an empty default for the 'RemoteBinding' class in my jar/ear. Is that possible? Or can i use some dependency containing a 'RemoteBinding' class which is compatible with JBoss 7 just to suppress the error?

       

      Thank you in advance.

       

      Cheers,

      Stefan
