Integration

Hi

I get the following errormessage if I try to apply a more recent build of the JPA Toplink Essentials.
If I use the glassfish-persistence-installer-v2-b45.jar all things work fine, but if a try to upgrade my program will fail. I tried the glassfish-persistence-installer-v2-b54.jar, all also tried all builds between?!
I have no idea how I may resolve the problem?!
Any ideas?

Thanks

Marcel
