    Hibernate/JPA & JBoss 4.2.2 - DuplicateMemberException: dupl

    Guillaume Jeudy Master

      Hi,

      Though originally posted in JBoss Seam forum, it seems to me that this issue is not related to seam but to JBoss 4.2.2 Hibernate/JPA integration.

      I'm getting a duplicate method getId() at startup with 2 JPA Entity classes which I didnt get in jboss 4.0.5. Since the issue only appears on 2 Entity classes I expect these should be fixable and not become a show stopper to the upgrade to jboss 4.2.2.

      One of the faulty JPA entity looks like this:

      @Entity
      @Name("productLookup")
      @DiscriminatorValue("PRS")
      public class ProductImpl extends SpecificationImpl implements Product {
      
      }


      getId() method is implemented in SpecificationImpl

      public java.lang.Long getId() {
       return specificationId;
       }


      The method getId() is declared on Specification interface implemented by SpecificationImpl.

      SpecificationImpl has no superclass (i.e. Object)

      @Entity
      @Table(name = "SPECIFICATION")
      @Inheritance(strategy=InheritanceType.SINGLE_TABLE)
      @DiscriminatorColumn(
       name = "TYPE_CD",
       discriminatorType=DiscriminatorType.STRING
      )
      public class SpecificationImpl implements Specification


      Product interface extends Specification interface which extends in turn ReferenceDomainInstance interface. I noticed the later 2 interfaces also extend java.io.Serializable. I think I read somewhere only concrete JPA Entity classes should implement Serializable, is this what could be wrong here ?

      public interface Product extends Specification


      public interface Specification extends Serializable, ReferenceDomainInstance


      public interface ReferenceDomainInstance extends Serializable, Comparable<ReferenceDomainInstance>


      Below is the stacktrace:
