I'm using Hibernate Core (non-standard). Looking into using OpenJPA or 
an alternative such as Hibernate EntityManager, is on my to-do list. I 
just wanted to get the familiar Spring+Hibernate (Core) running first.
As such, I can't say to what extend (if any) I need to use Hibernate 
Core instead of JPA.

Is there any reason why Hibernate Core shouldn't be supported on 
Geronimo (implied it uses Geronimo managed DataSource and JTA/CMT 
transactions)? Seems to me that the Spring+Hibernate combination is 
pretty common.

Best regards,

Jonas Andersen
