I have changed some jpa properties of my entityManagerFactory, and everything looks like ok... | <property name="jpaPropertyMap"> | <map> | <entry key="hibernate.current_session_context_class" value="jta"/> | <!-- entry key="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory"/ --> | <entry key="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereTransactionManagerLookup"/> | </map> | </property> | Now the next step watching jboss cache statistics.
