As requested I wrote a test that consisted of the following code... Injected session: | @PersistenceContext(unitName="PicsEM") | Session session; | Method content: | try | { | Statement s = this.session.connection().createStatement(); | String del = "DELETE FROM ZCOREINV.COUNTRY WHERE ZCOREINV.COUNTRY.ID = '158';"; | s.execute(del); | this.session.close(); | } | catch (HibernateException e) | { | e.printStackTrace(); | } | catch (SQLException e) | { | e.printStackTrace(); | } | The test failed in exactly the same way as before.
