Code between sessionFactory.openSession() and session.close():

Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();

Event theEvent = new Event();

theEvent.setDate(theDate);
theEvent.setTitle(title);

session.save(theEvent);
System.out.println("isS COnnecTED : "+ session.isConnected());
System.out.println("WAS COMMITED : "+tx.wasCommitted());
session.flush();
tx.commit();
System.out.println("After Commit");
System.out.println("WAS COMMITED : "+tx.wasCommitted());

session.close();
}catch(ArrayIndexOutOfBoundsException e){
System.out.println("EXCEPTION :: "+ e);
e.printStackTrace();
}
catch (HibernateException e) {
e.printStackTrace();
}

The problem can be solved using postgresql new driver named pg74.215.jdbc3.jar...
Copy this particular jar to JBOSS_HOME/server/default/lib and restart the server.

Be carefull, This driver won't work with WebRowset and CachedRowSet...
If anybody got that problem solved please forward that to the forum
