 Post subject: Looking for Annotations Despite exclude-unlisted-classes

Hi, everyone.

I am converting from TOPLink Essentials to Hibernate 3.4, both using JPA, all inside of Spring 2.5, inside of Tomcat 6, running against MySQL 5.

My application currently functions with TOPLink. To convert to Hibernate, I updated the files below.

I'm not using any annotations, only the orm.xml for mapping. However, I get the exception below, seeming to indicate that Hibernate wants an ID defined for that first entity.

I'm using exclude-unlisted-classes, which I didn't seem to need with TOPLink, but I understand I need with Hibernate. The Spring docs say to use it like I do below, but I've also tried putting a true in there, but the same thing happens.

I'm not sure if my persistence.xml is not being picked up (it's in a META-INF in one of my jars), but it's in the same place as it was for TOPLink (same with the orm.xml which Hibernate seems to find).

I've searched around and found the same error but not the same context.

Any help is greatly appreciated.

Hibernate version: 3.4.0
