      I'm working with JBOSS 4.2.3 and JPA/Hibernate, and Postgress.
      I managed to create my tables, but then I created a new class to be mapped as a new tables but when I deploy the jar,I got the following error:

      Problem starting service persistence.units:unitName=JPAResources
      javax.persistence.PersistenceException: org.hibernate.HibernateException: cannot
      simultaneously fetch multiple bags

      --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---

      JPAResources is the name of may persistence-unit
      JPAResources.jar is the name of the jars containing the classes and de pesistence.xml file

      I will apreciate any help you can provide me.
      Thanks
