Hibernate core vs Hibernate through JPA api

[Michael Enudi]

Hello All,

I have been quizzing myself through this lately trying to find out which is a better way to use hibernate: Hibernate core vs Hibernate through JPA api.

I have been using JPA api for over four years now and simply define the implementation framework in my Persistence.xml file. The rest of course is left to the implementation as I simply code against interfaces.
I have also attempted to use Hibernate implementation through JPA but have never used Hibernate core (simply because I don't want to learn a new HQL).

My question therefore is that for those with experience with any of both method, what would be the gains and loss of using one as against the other.

Many thanks.

I do like to use Hibernate through JPA api because if you need to move from Hibernate to Toplink you will not need to change the classes code.

Only the persistence.xml and the jar. For performance I do not have any data about that. =/

We share the same view and currently that is what I do but I would really like to know what I could have been missing by not building on Hibernate core or using HQL.
Thanks
