I am using the HibernateUtil in my DAO class to retrieve the current session, as such:

Session currentSession() {
        return HibernateUtil.currentSession();

The util works fine when the DAO methods are called from my controller, but if I call from SessionInit, i.e.
public class SessionInitiator implements SessionInit {

    public void init(Session sn, Object o) throws Exception {
           User user = new AuthDAO().findUserByUsername("a_user_name");
           sn.setAttribute("user", user);//set user to session

I get this error:

WARNING: StandardWrapperValve: PWC1406: Servlet.service() for servlet auEngine threw exception
org.hibernate.HibernateException: get is not valid without active transaction

Why is this? Thanks

Hi RichardL,
Try to use "HibernateUtil.getSessionFactory().openSession() " instead of using "HibernateUtil.getSessionFactory().getCurrentSession()".
