AndyW commented on HHH-5287:
----------------------------

please close the issue, because the problem was on my side. using @MappedSuperclass and @Entity in one class does not make sense. thanks.

> hi,
> i am using 
> Hibernate Annotations 3.4.0.GA
> Hibernate EntityManager 3.4.0.GA
> Hibernate 3.3.2.GA
> with JPA 1.0
> hibernate fails to create the entities using a SINGLE_TABLE Inheritance when the Discriminator is
> part of the composite primary key. I have attached a testcase. 
> hibernate is expected to only create a table LADEEINHEIT_EINAUS. however it also creates
> a table for each of the two entities that extend the base class and defines a DiscriminatorValue
> @Entity
> @DiscriminatorValue("EINGANG")
> public class LadeeinheitEingaenge extends LadeeinheitEinausgaenge 
> @Entity
> @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
> @DiscriminatorColumn(name = "LAEA_TYP", discriminatorType = DiscriminatorType.STRING)
> @Table(name = "LADEEINHEIT_EINAUS")
> @MappedSuperclass
> public abstract class LadeeinheitEinausgaenge
> i have executed the same code using EclipseLink. EclipseLink only created one table 'LADEEINHEIT_EINAUS' 
> which is what i expected.
