I updated the blog entry by the single working PL.
http://www.jroller.com/HazemBlog/entry/implementing_hibernate_open_session_per
*Here it is:*
public class OSPVFPL implements PhaseListener {
public void beforePhase(PhaseEvent event) {
SessionFactory sessionFactory =
HibernateSessionFactory.getInstance();
sessionFactory.getCurrentSession().beginTransaction();
}
public void afterPhase(PhaseEvent event) {
SessionFactory sessionFactory =
HibernateSessionFactory.getInstance();
try {
sessionFactory.getCurrentSession().getTransaction().commit();
} catch (Throwable ex) {
// very bad error here, occured...
if (sessionFactory.getCurrentSession().
getTransaction().isActive()) {
sessionFactory.getCurrentSession().
getTransaction().rollback();
}
}
}
public PhaseId getPhaseId() {
return PhaseId.INVOKE_APPLICATION;
}
}
