More Migration Woes

ryoung2504 Jul 12, 2005 4:41 PM

I'm just migrating some code from Preview 5 to Beta.

Previously I had an abstract class that had @Id and @Column annotations but no @Entity annotation on the class. I entended this with two classes that were annotated with @Entity. This gave me two tables with the same structure and no redundant code.

Now when I try to deploy this pattern on the Beta version of EJB3 I get "org.hibernate.AnnotationException: No identifier specified for entity:"

Short of moving the code from the abstract class into the two concrete classes (which will produce some duplication) is there a way to do this in the latest version of EJB3?

The spec has clarified this area.
map your superclass with @EmbeddedSuperclass (have a look at the doc for more infos)
