Integrating JTA, Hibernate 4 and Spring 4 with WebLogic
hibernate, jta, spring, weblogic
Solution
Based on the answer from @M. Deinum (if you put your comments in an answer, I'll mark it as correct), I have figured out the problem.
The solution was to add the data source (referencing the JNDI data source I specified earlier) as `<property name="dataSource" ref="NCS"/>`. I also reference the jtaTransactionManager as `<prop key="hibernate.transaction.jta.platform">org.hibernate.service.jta.platform.internal.WeblogicJtaPlatform</prop>`
NOTE: for other servers other than WebLogic, replace `.WebLogicJtaPlatform` with your specific server's JtaPlatform name. Specific implementations can be found at http://docs.jboss.org/hibernate/orm/4.1/javadocs/org/hibernate/service/jta/platform/internal/AbstractJtaPlatform.html
Finally, I changed the `sessionFactory.openSession()` to `sessionFactory.getSession` in my DaoImplementation file.
I hope this helps someone else as well!

Problem
I am having serious issues with implementing a JTA / Hibernate / Spring application (with WebLogic 10.3 for the server). I originally was using the Spring programmatic configuration, but have moved it over to the Spring XML configuration to filter out potential problems. It was working perfectly when I used the HibernateTransactionManager instead of the JtaTransactionManager, but now is not finding the Session for the thread. When I look at the sessionFactory it is not null, but getSession() does not return a session. Could you assist me in troubleshooting this? Thank you! My Dao implementation: ``` import java.util.Collection; import java.util.LinkedHashSet; import java.util.List; ... import org.hibernate.Criteria; import org.hibernate.Hibernate; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.criterion.Restrictions; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; import mil.navy.navsupbsc.utilities.HibernateConfiguration; @Repository public class ContactDAOImpl implements ContactDAO { @Autowired SessionFactory sessionFactory; public Session getSession() { try { sessionFactory.openSession(); return sessionFactory.getCurrentSession(); } catch (NullPointerException e) { e.printStackTrace(); throw e; } } @SuppressWarnings("unchecked") public List<Contact> listContact() { List<Contact> contactList = getSession().createCriteria(Contact.class) .list(); ... ``` My Spring-Servlet.xml file is: ``` <?xml
