I am trying to deploy hibernate (3.1.3) in OC4J 10.1.2. When I attempt to run my application I get the following exception:

org.hibernate.HibernateException: Unable to locate current JTA transaction
at org.hibernate.context.JTASessionContext.currentSession(JTASessionContext.java:61)

This happens after I make a call to SessionFactory.getCurrentSession(); I am not sure if this is a configuration issue of if there is an incompatability between hibernate and OC4J 10.1.2. I have tried reading up on the configuration of both the app server and hibernate and have tried different configurations. They all seem to lead to the same excpetion. Has anyone seen this issue? Also if you have gotten hibernate to work in OC4J it would be good to know that it is not an compatability issue. Thanks.


Here is the hibernate config:

<hibernate-configuration>
<session-factory>
<property name="hibernate.cglib.use_reflection_optimizer">true</property>
<property name="hibernate.connection.datasource">jdbc/DevDS</property>
<property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.OC4JTransactionManagerLookup</property>
<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property>
<property name="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</property>
<property name="hibernate.cache.use_minimal_puts">true</property>
<property name="hibernate.cache.use_query_cache">true</property>
<property name="hibernate.transaction.auto_close_session">true</property>
<property name="hibernate.transaction.flush_before_completion">true</property>
<property name="hibernate.current_session_context_class">jta</property>
<property name="show_sql">false</property>
</session-factory>
</hibernate-configuration>

Doesn't seem like a problem with Hibernate though. The transaction manager is there, it just returns null for transaction. According to the code in org.hibernate.context.JTASessionContext class if transaction manager returns null, the context is not trying to begin a new transaction but throws HibernateException. Here's the exact place (lines 59-62):



I don't know if the context should try to start a new transaction when this happens. Probably not. It's the application server's job to do JTA.

Any help is appreciated.

Thanks.
