Hi,

i am trying to get the UserTransaction working with Hibernate, but having massive problems in resolving my issues.

I already did what has been written in hibernate tutorials with usertransactions and jboss, but hibernate won't synchronize with the JTA.

Generally i do the following in my application:
0) SessionFactory set up
1) In each Constructor of a bean: getting the UserTransaction and beginning it (works without hibernate)
2) try to get the current session in hibernate (won't work-->Exception)
3) try to use the getters and setters of my loaded objects (won't work because of 2)
4) in finalize method of each bean: commit the transaction (won't work because of 2 - but without hibernate it works fine)

I try to get hibernate not to load the complete object-path at once. I thought to use jbossusertransaction and wrap my application with it (step 1-4): If i call a get-method of my objects in step 3) hibernate will load it once the get-method is accessed. But i won't get that far because i am stuck in 2).

Maybe i did something wrong or somebody knows a better way to use transactions in jboss with hibernate.

Many thanks in advance,

Ingo

It would be of some help to post the exact exception you got in step 2.


Am I understanding you correctly?
point 2) says: you are creating a new transaction in the constructor of your persistent entities.

If that's true, that is of course the reason for your problem.

If you want to work with UserTransaction the general usage pattern is like that:

1. Start your transaction in your service bean or DAO and therin at the begin of a service method, not in the constructor.
2. Call SessionFactory.getCurrentSession() and work with it.
3. At the end of your service method call commit() or rollback() on the UserTransaction.

Normally their is absolutely no reason to access the UserTransaction from within persistent objects aka entities.
