Hi, I'm having trouble using Hibernate 3 with bean managed transactions (BMT). I have currently adopted a thread local approach to transaction management, but I would prefer to use the global transaction provided by my J2EE container (Websphere version 5.1). Also, as an FYI, my database is DB2, version 8.1

In my hibernate config file, I have the following items:
<property name="hibernate.transaction.factory_class">
org.hibernate.transaction.JTATransactionFactory</property>
<property name="jta.UserTransaction">
java:comp/UserTransaction</property>
<property name="hibernate.transaction.manager_lookup_class">
org.hibernate.transaction.WebSphereTransactionManagerLookup</property>

Furthermore, my EJB's are configured for BMT. When I invoke the code:
sessionFactory.getCurrentSession(), hibernate throws a HibernateException...the excepiton is "Could not located global transaction"

I'm not sure why this error arrises. I have written a test case that does a JNDI lookup of "java:comp/UserTransaction" and I am able to find the UserTransaction object without problem.

Anyone have any ideas?

Thanks...
Mike

did you solve your problem?
I have a similar one, if I do tx.begin() before sessionFactory.getCurrentSession() it works and I can read from the database, but later on it does not write to the database when I commit()...

Have you solved the problem ?

I have got the same problem. If you solved , how did you solve it ?

Thanks,

JSV.

You must start transaction if you are using BMT, "currentSession" is mapped to transaction.

can you say what is the BMT means please ?
