Hibernate and instandDB

I have been using Enhydra, Barracuda and DODS very well.

I have decided to use less of DODS and move to hibernate instead as there
were some good reviews on it.

The DB I am using at the moment is InstantDB.

Are there any issues with using Hibernate with instantDB.
If there is some modification or setup can you guys let me know in advance.

Cheers.
