Hello,
I already have a huge application uses hibernate & derby, I don’t have an application server running, only Tomcat web server.
I got tired of managing transactions myself :( most of my problems appear because of the sessions & transactions, and some of them because of loosing the DB connections & deadlock due to none lazy relations & multi threading!!

I’m trying to revamp my work slowly, so I’m thinking to use a stand alone transaction manager, so it can help me in order to manage the transactions.

Question:
1- Doe’s anybody know a good transaction manager library so I can use it.
2- What is the impact of this change on my code (my hibernate DAO classes) according to that?


Thanks,
