I apologize for not giving all the details
Hibernate version 2.1 using MS SQL Server 2000
Code for closiong and opening session.
public static Session currentSession() throws DAOException {
Session s = (Session) session.get();
try {
if (s == null) {
s = getSessionFactory().openSession();
session.set(s);
System.out.println("Creating session");
}
} catch (HibernateException he) {
he.printStackTrace();
throw new DAOException(he);
} finally {
}
return s;
}
public static void closeSession() throws DAOException {
Session s = (Session) session.get();
session.set(null);
System.out.println("------");
if (s != null) {
try {
s.close();
System.out.println("Closing session");
} catch (HibernateException he) {
throw new DAOException(he);
}
}
}
This mapping works in at other places and I don;t any problem with this mapping. This is for your reference
