Pavel, look at hibernate config values for the following. The ones with question-marks I can't help you with - I'm using local wrappers, and can't take time to look up generic solutions. Check the Hibernate docs, etc for these properties. I'm (obviously) on WebLogic - you'll need different values for other containers. -Ed Staub <!-- CMT transaction properties (begin) --> | <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> | <!--property name="hibernate.transaction.manager_lookup_class">????????????????????????</property> --> | <!-- CMT transaction properties (end) --> | | <!-- JTA transaction properties (begin) === | <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property> | <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WeblogicTransactionManagerLookup</property> | === JTA transaction properties (end) --> | | <!-- CMT transaction properties (begin) --> | <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> | <!--property name="hibernate.transaction.manager_lookup_class">????????????????????</property> --> | <!-- CMT transaction properties (end) --> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4157412#...
