Could it be that you need to store your session somewhere? Perhaps on the
ThreadLocalSessionContext, or your HttpSession? That way you can retrieve
and use the one you created. Your transaction code afterPhase looks ok. I
have had success storing the Hibernate Session on the HttpSession.
In the PL:
static{
sf = SessionFactorySingleton.getInstance().getSessionFactory();
}
Try this for the before phase:
public void beforePhase(PhaseEvent phaseEvent) {
ThreadLocalSessionContext.unbind(sf );
Session hibernateSession =
(Session)getHttpSession().getAttribute(SESSION_ATTR);
if(hibernateSession == null || !hibernateSession.isOpen()) {
log.debug("No Hibernate Session found on HttpSession, create and
bind");
ThreadLocalSessionContext.bind(sf.openSession());
hibernateSession = sf.getCurrentSession();
} else {
ThreadLocalSessionContext.bind(hibernateSession);
}
addHttpSessionBean(SESSION_ATTR,hibernateSession);
log.debug("Starting a database transaction");
sf.getCurrentSession().beginTransaction();
}
Then your afterPhase call should work ok.
Hope that helps

Hi Hazem,
I have implemented as per your suggestion using a single PL.
The PL is registered in facesConfig.xml and the hibernateconfig file has
<property name="current_session_context_class">thread</property>
still I am getting
"org.hibernate.LazyInitializationException: could not initialize proxy - no
Session" error
Any clues ?
==========================================
=========================================
public class RestoreViewPhaseListener implements PhaseListener {
public void beforePhase(PhaseEvent event) {
SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
sessionFactory.getCurrentSession().beginTransaction();
}
public void afterPhase(PhaseEvent event) {
SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
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;
}
}
=========================
HibernateUtil.java
==========================
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new
Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." +
ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
Can you tell me if I am missing anything here?
Thank you.
Regards
Ayub

Hi Ayub,
I tried this code before and it worked fine.
You should check your hibernate configuration, and make sure that:
1. You are registered your PLs.
2. <property name="current_session_context_class">thread</property>.
Another better idea, I got later, you can use only one PL on the
(INVOKE_APPLICATION) phase to implement the OSPVP.
Thank you.

Hi,
I have impleted the phaseListener using the idea presented on
http://www.jroller.com/HazemBlog/entry/implementing_hibernate_open_session_p
er
I am getting "org.hibernate.HibernateException: createQuery is not valid
without active transaction" error message.
Below is the code of phase listeners:
public class RestoreViewPhaseListener implements PhaseListener {
public void afterPhase(PhaseEvent event) {
}
public void beforePhase(PhaseEvent event) {
SessionFactory sessionFactory =
HibernateUtil.getSessionFactory();
sessionFactory.getCurrentSession().beginTransaction();
}
public PhaseId getPhaseId() {
return PhaseId.RESTORE_VIEW;
}
}
Please let me where to open and close session and transaction.
Thanks
Ayub
