Problem with Hibernate3 on WAS 5.1

[markus lehrhuber]

I have a problem running Hibernate 3 on Websphere 5.1. I always get the following error when building the hibernate sessionfactory
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

org.hibernate.HibernateException: Unable to locate current JTA transaction

My config file looks like follows:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.session_factory_name">HibernateSessionFactory</property>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property>
<property name="hibernate.connection.datasource">jdbc/MyDataSource</property>
<property name="hibernate.transaction.factory_class">
org.hibernate.transaction.JTATransactionFactory
</property>
<property name="hibernate.transaction.manager_lookup_class">
org.hibernate.transaction.WebSphereTransactionManagerLookup
</property>
<property name="hibernate.jndi.class">
com.ibm.websphere.naming.WsnInitialContextFactory
</property >
<property name="hibernate.current_session_context_class">jta</property>

<mapping resource="User.hbm.xml" />

</session-factory>
</hibernate-configuration>

Can anyone help me? Thanks!

As for the exception that you are seeing, can you post the entire exception stacktrace?

Markus, thanks for changing your display name

[07.07.07 15:14:13:328 CEST] 38deb49a SystemErr R org.hibernate.HibernateException: Unable to locate current JTA transaction

So the exception is occuring when you are calling the getCurrentSession method and not while building the session factory. Is your listLoggingsWithQGNameAndUserName part of a transaction?

oh yes you are right - I got several stackraces because I tried a lot of different configurations.

But now it seems to work - it seems that the same WAS-Datasource was used by another Application which prevented hibernate caused this error.
