 Post subject: Annotations vs XML files with Hibernate in Eclipse

Need help with Hibernate? Read this first:
http://www.hibernate.org/ForumMailingli ... AskForHelp
Read that. Also read the first 6 chapters of Java Persistence with Hibernate. I've successfully reverse-engineered the legacy DB using the Hibernate tools (though Ant) and created a JPA project in Eclipse to allow me to work on the code. My problem is that Eclipse won't let me create a Hibernate project - only a JPA project (which expects full use of persistence.xml and orm.xml) and I want to use Annotations. However, using Annotations with the empty skeletons of xml files causes JPA errors at the Entity annotations that the entity cannot be resolved. Adding the entities to persistence.xml through <class> tags removes the errors at the Entity tags and now complains about every column name as
Quote:
cannot be resolved
.

I can generate a Hibernate Console Configuration (and have), but that doesn't remove the errors. Is there a way to remove the errors besides listing all the classes and all their attributes in the xml files?

All help is greatly appreciated.

Craig

We are using a 100% annotation based mapping system with Hibernate and Eclipse and it works fine. We don't have any xml mapping files apart from persistence.xml which looks similar to yours, that is it defines the PU and the entity classes. Have you tried removing orm.xml?

Nice try, but I still get the same result.
