Hello,

After Migrating an Application J2EE from JDK 1.4 to JDK6, WAS6.1 to WAS7, EJB2 to EJB3 (Ejb session: persistence with Hibernate3.2 : No JPA); An Error is blocking transaction to an DB Oracle (We use JTA).

Error traced : "Current transaction is not in progress".

This error is occured when we tray to instanciate/recupere current session hibernate from SessionFactory:

sessionFactory.getCurrentSession();

Extract of file config Hibernate.cfg.xml:

<hibernate-configuration>
<session-factory>
<property name="session_factory_name">Mgb/HibernateFactory</property>
<property name="show_sql">false</property>
<property name="connection.datasource">jdbc/mgb</property>
<property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
<property name="hibernate.jta.UserTransaction">java:comp/UserTransaction</property>
<property name="hibernate.current_session_context_class">org.hibernate.context.JTASessionContext</property>
<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
<property name="hubernate.transaction.manager_lookup_class">org.hibernate.transaction.WebSphereExtendedJTATransactionLookup</property>
. .
</session-factory>
<hibernate-configuration>

Do you have any idea which could be the issue ?
Thanks in advance
