I couldn't agree more, Shark *almost* got alternative db layer, but...
Vladislav has finished his work (on hibernate implementation) before we
did finished interface... :(
At that time Shark was *beta*, and we were extensively changing things
(interfaces included). Now, as version 1.0 is released, I doubt
interfaces will change that much :).

Can you share with us, what's the problem with DODS generator? We should
fix it anyways. How does it crash?

In HibernatePersistentManager there are exactly six (6) methods throwing
PersistenceException("Not implemented yet!"). Also Buffer has been
changed in the meantime.
As for the bug we saw originally, there are problems with restoring
process/activity variables (read: BLOB columns) from database, but we
didn't investigate further.

I would recommend to go component at a time. There are eight separate
database components, but most important are InstancePersistence, buffer
and counter (SharkUtilities/Hibernate).

If you decide to do it (or anybody else), we'll help you as much as we
