    Welding problems with generic ejb producer

    Anders Åberg Newbie

      Hi guys


      I am trying to make a producer method that can produce references to our remote EJB's, basically a replacement for @EJB. The purpose is to be able to introduce proxies on the client side, caching, and dynamic remote host configuration.


      I have got the plumbing in place, but I'm having problems welding it all together.. What I would like to do is this:


      @Inject @Service
      private StatusService statusService;



      Where a producer method is able to find the right service. And my working producer method looks like this:


      @Produces @Service
      public StatusService getStatusService(InjectionPoint ip) throws NamingException {
           return lookupRemoteEJB((Class)ip.getAnnotated().getBaseType());
      }
      



      But, if I change the return type of this method to BaseService (which StatusService inherits from), or just Object, I get this exception:


      UnsatisfiedResolutionException: WELD-001308 Unable to resolve managed beans for Types: [interface no.evote.service.StatusService]; Bindings: [@no.evote.presentation.Service()]



      Which is sort of..unsatisfying.


      StatusService looks like this:


      @Service
      public interface StatusService extends BaseService {
      ...
      }



      And @Service is a qualifier:




      @Target( { TYPE, METHOD, PARAMETER, FIELD })
      @Retention(RetentionPolicy.RUNTIME)
      @Qualifier
      @Inherited
      public @interface Service {
      }






      Is there any way I can keep the producer method generic while still having the clean injection syntax?


      Regards,
