    Can I reference or inheritance between two jar files?

    joeyli Newbie

      I have two EJB3 subsystem:
      Auth system: was packed in auth.jar file
      and
      Order system: was packed in order.jar file

      Now, I have a entity bean that's name is EOlocation, and it was packed in auth.jar:

      @Entity
      @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
      public class EOlocation implements Serializable {
      @ManyToOne
      @JoinColumn(name = "eoaccount_id")
      private EOaccount account;
      .....
      }


      Another entity bean is EOorderLocation, it's a subclass for EOlocation, but was packed in order.jar

      @Entity
      public class EOorderLocation extends EOlocation {
      .......
      }

      I am deploy the auth.jar before than deploy the order.jar file.
      Than I get the exception like the following:

      15:15:15,897 WARN [ServiceController] Problem starting service persistence.units:unitName=EatOutDS
      org.hibernate.AnnotationException: @OneToOne or @ManyToOne on com.tweatout.auth.domain.EOlocation.account references an unknown entity: com.tweatout.auth.domain.EOaccount

      How can I implement the reference or inheritance entity bean between two jar files?
