Weld's @Inject cannot be used in a no-interface session bean

    Details

      Description

      The session bean:

      @Stateless
      public class Kundenverwaltung {
      @PersistenceContext
      private EntityManager em;

      @Inject
      private KundenverwaltungDao dao;
      ...
      }

      The CDI bean:
      @Named
      public class KundenverwaltungDao {
      @PersistenceContext(unitName="hskaPersistence")
      private EntityManager em;
      ...
      }

      The deployment results in a NPE:
