Hello,

I'm using OSWorkflow, which currently manages its own persistence with Hibernate 2. Spring loads it, so whatever Spring interfaces use OSWorkflow must also use Hibernate 2.

The primary Hib2 objects I see being used are SessionFactory, Session, Criteria, Expression, and HibernateCallback.

My questions is, could I expect any performance gain if I moved OSWorkflow completely to Hibernate 3? The mapping files between the 2 versions are the same. The only real difference I've noticed (at least in OSWorkflow) is the packages the Hibernate classes mentioned above come from. The only reason this is even worth considering is that there's a lot of code I'd need to write for OSWorkflow to use Hibernate 3, and I want to be sure it's worth the effort.

So to sum this all up - Is there a big difference between Hibernate 2 & Hibernate 3? :-)

Thanks.

yes and no. read the hibernate 3 migration guide. (search on our wiki)
