Use JPA with JDBC Transaction isolation

Hello,

how is it possible to configure Hibernate while using JPA Annotations and entitymanager to use Transaction demarcation with plain JDBC?

The examples and tutorials do this while accessing the Session through the factory and start an transaction, like described here: http://hibernate.org/42.html

I haven't found an option to set this in case of JPA. Since i don't create the EntityManager/Factory through the configuration of Hibernate.

How can I accomplish this?

Hibernate version: 3.2.6

thanks for the Help

you can still set all hibernate-specific options in persistence.xml

Hey thanks for the answer,
but i figured out a much simpler way:

Code:

EntityManagerFactory emf = Persistence.createEntityManagerFactory("myunit");

EntityManager em = emf.createEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();

// persist and do stuff

tx.commit();

But yesterday after hours of looking for the wrong places, I just could not figure that out.

thanks again.
