Just figuring out what jars to put in my application drove me away. TopLink was a single jar. Besides, why Hibernate and not TopLink? :) James,

Thanks Hi Romain,

May I know why you don’t want to use hibernated with JPA?

Thanks

The orm.xml file is a way to externalize your configuration and override all or some of your annotations so they can be changed without having to recompile your code. This is of course a moot point when you are using Groovy :) You can have multiple orm.xml files and specify the names in the persistence.xml file. I have no idea why specifying the class in the orm.xml file works while specifying it in persistence.xml doesn't. Hopefully someone from the TopLink project can shed some light here.

I was indeed using a snapshot of Groovy that does support annotations, which is not Groovy 1.0. What is orm.xml? How is it different from specifying <class /> entries in persistence.xml? I'll use this until a fix is found in either Groovy and/or TopLink though. Thanks again! Thomas, thanks a lot!

Groovy 1.0 doesn't work with the annotations but built a current snapshot of Groovy 1.0.1 and now the JPA annotations are picked up. I still need a minimal entry in orm.xml to get the class to be found - probably a classloading issue. If I use this <entity class="Person" name="Person" metadata-complete="false" access="FIELD"> </entity> in orm.xml instead of referencing the class in persistence.xml everything works OK.
