Struts2: unable to load HibernateSessionFactory.getSession()

Question

I am running an application on JBoss server which is developed using struts2 & Hibernate. But I am facing a problem in my getEmployee method of LoginDAOImpl class.The code is as below:-

@SuppressWarnings("unchecked")
public List<UserView> getEmployee(String empId) {
    Session session = null;
    List<UserView> list = null;
    try {
        System.out.println("in LoginDAOImpl getEmployee : 1 ");
        session = HibernateSessionFactory.getSession();
        System.out.println("in LoginDAOImpl getEmployee : 2 " + session);
        String str = "from UserView  where empId='" + empId + "'";
        list = session.createQuery(str).list();
        System.out.println("LoginDAOImpl.getEmployee()::" + empId);
    } catch (HibernateException e) {
        e.printStackTrace();
    } finally {
        HibernateSessionFactory.closeSession();
    }
    return list;
}

On Console Iam getting "in LoginDAOImpl getEmployee : 1 " but i am not getting "in LoginDAOImpl getEmployee : 2 ".That means it is not able to find Hibernatesessionfactory class.But I have included Hibernatesessionfactory in my path. I have included jars for Hibernate :- hibernate3.jar,hibernate-annotations-3.2.1.ga.jar,hibernate-annotations.jar,hibernate-commons-annotations.jar,hibernate-entitymanager.jar,hibernate-valid

Try

session = HibernateSessionFactory.openSession();

Actually in my HibernateSessionFactory class there is no openSession method..so it is showing error after writing – 3076843 Dec 30 '13 at 11:50

You can give something like :

     @SuppressWarnings("unchecked")
        public List<UserView> getEmployee(String empId) {
                private static SessionFactory factory; 
                 try{
                      factory = new Configuration().configure().buildSessionFactory();
                 }catch (Throwable ex) { 
                    System.err.println("Failed to create sessionFactory object." + ex);
                     throw new ExceptionInInitializerError(ex); 
                 }

            Session session = null;
            List<UserView> list = null;
            try {
                System.out.println("in LoginDAOImpl getEmployee : 1 ");
                session = factory.openSession();
                System.out.println("in LoginDAOImpl getEmployee : 2 " + session);
                String str = "from UserView  where empId='" + empId + "'";
                list = session.createQuery(str).list();
                System.out.println("LoginDAOImpl.getEmployee()::" + empId);
            } catch (HibernateException e) {
                e.printStackTrace();
            } finally {
                session.close();
            }
            return list;
        }
