Which JPA Implementations work?

Hello,
besides the included Toplink, which other JPA implementations work with Glassfish V2 beta 2 or newer? I tried Hibernate and OpenJPA according to some older blog entries that I found and apparently that information is outdated, as I'm getting exceptions all over the place when following the instructions.
So, are there any current experiences of switching from Toplink to another implementation?

Hi,
I'm using JPOX. It's open source (Apache 2.0 license) and supports both JPA and JDO standards.
In my project works fine.
ciao,
Luca Garulli

We track both OpenJPA and Hibernate; if there are problems plugging
tghem in, we should try to fix them...

Hello. All JPA implementations works in Glassfish. But the problem is that you must make sure that the library does not conflict between the current JPA implementations that is bundled with Glassfish (which is Toplink essentials). This is the tricky part to do

What sort of conflicts are you seeing? I have not come across any such
issues while trying Hibernate or OpenJPA.
Thanks,

I also used openJPA some time ago. I just neded to drop the jars into GF and modify the persistence provider property in my persistence.xml. It even was easily possible to switch between toplink and openJPA. From my experience I can say that the openJPA devs are very cooperative, if you have any trouble using openJPA.

GlassFish takes care of enhancement during deployment.

If you are using Java EE style JPA access (injection or lookup), the enhancement will happen automatically on entities load. So this change should not affect you.
