Is EJB inheritance through different EJB modules possible?

Question

Is it possible to have an entity class which inherits from another (abstract) entity class from another ejb module?

EclipseLink for example doesn't create the depending columns in database table of the subclass. It simply ignores the (abstract) superclass entity.

Answer 1

The annotation @Entity didn't work in my project but the annotation @MappedSuperclass which is also part of JPA 1.0 now works very well.

Sorry for that maybe stupid question. ;-)
