Re: enhancing entity which is a subclass
After looking at the spec, it looks like you should be using the mapped-superclass XML descriptor on the UserModelBaseImpl class and com.example.model.impl.UserModelImpl needs to be added to your list of persistent classes. See section 2.11 - 'Inheritance' for more details. Let me know how it goes! -Rick -- View this message in context: http://n2.nabble.com/enhancing-entity-which-is-a-subclass-tp612p3335590.html Sent from the OpenJPA Users mailing list archive at Nabble.com.

enhancing entity which is a subclass
Everything works with EclipseLink and TopLink but fails with OpenJPA. Tried with runtime as well as build time enhancement. The problem is the entity class is a subclass. In this test case, it is an empty class which inherits everything from the base class UserModelBaseImpl. ... ... ...
