I'm running a test case which tests my application's hibernate stuff which is deployed on a Weblogic 8.1 server.

here is the setup method

private Session session;
private Transaction t;

protected void setUp() throws Exception {
Configuration config = new Configuration();
config.configure();
SessionFactory sessionFactory = config.buildSessionFactory();
session = sessionFactory.openSession();
t = session.beginTransaction();
}


While doing a session.beginTransaction i get the following error.

Please, help me to solve this problem.

I included the relevant settings from our hibernate config file. We use WLS 8.1 SP6.



Try changing the transaction factory class from JTATransactionFactory to CMTTransactionFactory:

<property name="hibernate.transaction.factory_class">
org.hibernate.transaction.JTATransactionFactory
</property>

<property name="hibernate.transaction.factory_class">
org.hibernate.transaction.CMTTransactionFactory
</property>

And adding:

<property name="current_session_context_class">
jta
</property>

Retest calling getCurrentSession() instead of openSession() and post your results. Also, please let us know what version of Hibernate you are using. I seem to remember a similar problem in our environment when we tried a release candidate of Hibernate 3.2. We are currently using Hibernate 3.1.
