Hi,
I am getting problem with user transaction at the time server start. This problem is coming when hibernate session get closed. Details given below:-


Hibernate version: 3.2.0.cr3

Websphere version: 6.0.2

Mapping documents:
My Hibernate.cfg.xml looks as following:-
My SessionFactory configuration file looks as follows:
<session-factory>

<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>

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

<property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WebSphereExtendedJTATransactionLookup</property>


</session-factory>




Code between sessionFactory.openSession() and session.close():

Any help would be greatly appreciated, thanks in advance.

Try to add jta.UserTransaction property into your hibernate.cfg.xml file, like this:

<property name="jta.UserTransaction">
java:comp/UserTransaction
</property >

I have already done this but the response is the same.

Did you use Bean-Managed Transaction or Container-Managed Transaction? What type of container you use - web container or ejb container?

Try to use jta/usertransaction as the value of jta.UserTransaction property to your Hibernate.cfg.xml file, like this:

<property name="jta.UserTransaction">jta/usertransaction</property>

I'm using bean managed transaction and everything is runing inside the webcontainer only.....and below are the some of properties of my hibernate.cfg.xml




warm regards,

shikhar, as i understand, this isn't new problem. Look at this issue in Hibernate JIRA: http://opensource.atlassian.com/projects/hibernate/browse/HHH-198?page=comments#action_25691

and also to the post in this forum:
