Hello

I'm Using Teneo (http://wiki.eclipse.org/Teneo/Hibernate ... nd_Install) and Hibernate to map EMF objects into the Database.

Teneo 2.0.0 was released a few days ago, with Hibernate 4.1 support. http://martintaal.wordpress.com/2012/05 ... bernate-4/

So I'm trying to update from Hibernate 3.6.2 to 4.1.3. During startup I now get a lot of the following Warnings:
WARN: org.hibernate.ejb.AbstractEntityManagerImpl - HHH000326: Cannot join transaction: do not override hibernate.transaction.factory_class

I looked at the 3.6.2 code and found that Ejb3Configuration was setting JoinableCMTTransactionFactory as transaction factory class. In the new code CMTTransactionFactory is set, which seems to have less functionality than JoinableCMTTransactionFactory, since JoinableCMTTransactionFactory extends CMTTransactionFactory.
I do not manually set the factory class.

Do I have to configure a different factory? May this be a bug?

greets and thanks for help!

It was actually a problem of our Software at some place we called EntityManager.joinTransaction(), which is not required anymore in Hibernate 4.1.

I did have to set the following property to get CMT to work.
<prop key="hibernate.transaction.factory_class">org.hibernate.engine.transaction.internal.jta.CMTTransactionFactory</prop>
