Seems like this adresses the error. Why isnt my mapped superclass accepted? ;(

Internal Exception: Exception [TOPLINK-7243] (Oracle TopLink Essentials - 2.1 (Build b60e-fcs (12/23/2008))): oracle.toplink.essentials.exceptions.ValidationException
Exception Description: [b]Missing meta data for class [/b][de.myapp.core.model.AbstractEntity]. Ensure the class is not being excluded from your persistence unit by a <exclude-unlisted-classes>true</exclude-unlisted-classes> setting. If this is the case, you will need to include the class directly by adding a <class>[de.myapp.core.model.AbstractEntity]</class> entry for your persistence-unit.
