Hi,
I've created a utility class from which I'll obtain my sessionFactory which look as follows:
...................
static final Configuration configuration = new Configuration().configure();
System.out.println("PRE-CONFIGURE");
sessionFactory = configuration.buildSessionFactory();
System.out.println("POST-CONFIGURE");
................
I've also created my hibernate.cfg.xml file which I've placed in the conf dir of my Jonas appln server. When I call a method from my sessionBean which looks as follows:
..................
public void createUser() throws Exception
{
Session session = HibernateUtil.currentSession();
...............
...............
}
...............
I got a null pointer exception in Jonas. When I try to debug it I found that the jonas display my msg: PRE-CONFIGURE and then throws the nullpointer exception. So, it means there is something wrong in the line:
sessionFactory = configuration.buildSessionFactory();
Here is the msg from Jonas console:
