Hi guys,

I have had problems with hibernate 2 when using it in WAS 5.X. The problem concerns the management of transactions.
I have an EJB Session Bean method which requires a transaction. I have configured the .cfg.xml file to use JTATransactionFactory and a ConnectionProvider like this:

<!-- Part of my configuration file -->
<property name="connection.datasource">jdbc/qgraosDs</property>
<property name="dialect">net.sf.hibernate.dialect.OracleDialect</property>
<property name="connection.provider_class">br.com.project.hibernate.websphere.WSDataSourceConnectionProvider</property>
<property name="jta.UserTransaction">jta/usertransaction</property>
<property name="hibernate.transaction.factory_class">net.sf.hibernate.transaction.JTATransactionFactory</property>
<property name="hibernate.transaction.manager_lookup_class">net.sf.hibernate.transaction.WebSphereTransactionManagerLookup</property>

... (the mappings)

I implemented a connection provider class - br.com.project.hibernate.websphere.WSDataSourceConnectionProvider - as specified in Wiki Community Area Hibernate in WAS 5.x - fixes possible deadlock problem ( http://www.hibernate.org/204.html ).

Well, I have done all this and, in my DAO layer and I call hibernate open session and begin transaction before perfoming any database method such as findBykey, create, and after I commit the transaction and close the session.

So here is the problem, specfically, I get the following error messages when executing:

O O contador da sessão session_oracle foi inicializado: 1

I have tried changing the jta.UserTransaction property in the cfg configuration file but still it hasn´t worked. I tried:

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

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

- <property name="jta.UserTransaction">comp/UserTransaction</property>

So, can anyone please help me, show me a light at the end of the tunnel. I really need this help.

Thanks,
Carol

I've used the JTA Support for Hibernate in the Spring Framework and had it working just fine. Also, since JTA Support is part of Spring, their forum is a bit more active on the subject. Also, the Hibernate concepts in Spring are quite nice.

Hey

I have the same problem with JTA transaction lookup

I tried all the combinations u have tried.

Did u find any solution for that
