Hi,
I'm using Hibernate 2.1.1, Windows 2000, Jdk 1.3, WebSphere 4.02 and DB2 7.2. I'm having trouble using a websphere datasource. Here's what I do:

Code:

Session session = null;
try {
  session = SessionFactoryPlant.getSessionFactory().openSession( new RKTInterceptor());
  session.saveOrUpdate(case);   
} catch( HibernateException e ) {
  LOGGER.debug( "An HibernateException occured during saving, thrown as a PersistException", e );
  throw new PersistException( e );
} finally {
  if (session != null && session.isOpen() ) {
    try {
      session.close();
    } catch (HibernateException h) {
      LOGGER.warn("Exception while closing session.", h);
    }
  } 
}

This result in the following exception:

Code:

javax.transaction.TransactionRolledbackException: CORBA TRANSACTION_ROLLEDBACK 0 No; 

nested exception is: 
 org.omg.CORBA.TRANSACTION_ROLLEDBACK: com.ibm.websphere.csi.CSITransactionRolledbackException: 
 at com.ibm.ejs.csi.TranStrategy.commit(TranStrategy.java:194)
 at com.ibm.ejs.csi.TranStrategy.postInvoke(TranStrategy.java:67)
 at com.ibm.ejs.csi.TransactionControlImpl.postInvoke(TransactionControlImpl.java:414)
 at com.ibm.ejs.container.EJSContainer.postInvoke(EJSContainer.java:1772)

Here's the hibernate.cfg.xml:

Code:

<hibernate-configuration>
    <session-factory>
        <property name="show_sql">true</property>
        <property name="dialect">net.sf.hibernate.dialect.DB2Dialect</property>
        <property name="hibernate.transaction.factory_class">net.sf.hibernate.transaction.JDBCTransactionFactory</property>
        <!-- Database properties, in app server environment -->
        <property name="hibernate.connection.datasource">jdbc/rkt</property>  

Any ideas on what I'm doing wrong? All help appreciated!

Regards,
Ola

net.sf.hibernate.transaction.JDBCTransactionFactory is definately wrong for usage in an AppServer. You need to delegate transactions to the underlying JTA api. You need to use JTATransactionFactory, and set transaction manager lookup class. And stuff :) Sorry, have no conrete example here, search your way through the docs and the forum.

As you can see of my code, I'm not using the transaction API at all, and it still don' work...

Inside an appserver (suspect this is an EJB) you are allways using transactions (JTA). In any case, you should allways use transactions. And integrate Hibernate the way it is supposed with the AppServer and not in some crude JDBC based transaction way.

Try using the following settings...

Code:

<property name="transaction.factory_class">net.sf.hibernate.transaction.JTATransactionFactory</property>
<property name="transaction.manager_lookup_class">net.sf.hibernate.transaction.WebSphereTransactionManagerLookup</property>

Cheers
Chris
