[b]Hibernate version:[3.1.3]

We are planning to start using Hibernate in our browser based Enterprise Application. We are trying to implement it on a small part of our core structures to see how feasible it would be for us to use on the legacy code and database. Few queries regarding the same..

Intitially we wanted to keep one transaction open for all the read operations and keep on opening and closing other transactions for write operations (Since it needs a commit). But, it seems we cant keep two transactions open on the same session. So, we tried opening a new session for write operations, but again we cannot share the dettached object read from session 1 (which is still open) and save it through session 2.

I could read a obj from session 1, detach it by committing the transaction on session 1 and then reuse the object on session 2 by updating it. But, this would mean lot of sessions/transactions opening and closing.

Any suggestions on the basic design or path way to implement hibernate on the existing code?

Would hibernate 3.3 be of any help?
