Let me make one recommendation, Steve. Especially given that you have
used Hibernate before, and some time ago. Try not to use Hibernate
native APIs - stick to JPA. At least in a Java EE environment. I'm not a
Hibernate guy any more - haven't been since the first few years after it
came out - but I see that since 3.5 Hibernate has had JPA 2 support, and
I'd expect that by now it's in pretty good shape.

With JPA 1.0 there were sizeable API gaps that made forays into native
ORM (Toplink, EclipseLink, Hibernate, OpenJPA etc) APIs justifiable and
somewhat common. But even with JPA 1.0-compliant implementations you
could do most of your work with standard JPA. With JPA 2.0 it's much
more comprehensive.

Why use JPA at all? It's standard. It simplifies your reasoning about
persistence. Considering that there will still be plenty of need to
think about caching strategies, and persistent object lifetimes, and
query optimization, and object relationships, and lazy loading - in any
API and implementation that you choose - it's not a bad idea to
standardize and simplify what you can.

My 2 cents worth.
