Hi,

I am trying to use Hibernate as the OR mapping tool within WebSphere Application Server. loadParents method is a session bean method with TX attribute Required.

The data retrieval logic of session.find works fine standalone however when I add the update logic with the transaction begin and commit portion I get the exception trace attached. The config.xml is also attached for reference. Can any one provide a solution for the problem.


Hibernate version:2.1.2

Code between sessionFactory.openSession() and session.close():
public void loadParents(){
Session session = HibernateUtil.currentSession();
try {
Transaction t = session.beginTransaction();
List l = session.find(" FROM Parent p WHERE 1=1");

int parentCount = l.size();
for(int i=0; i<parentCount; i++){
Parent p = (Parent)l.get(i);
p.setMiddleName("CHG");
System.out.println("Parent: " + i+"--");
System.out.println(p);
session.update(p);
}
t.commit();
session.close();
} catch(HibernateException hibEx){
hibEx.printStackTrace();
}
}

Full stack trace of any exception that occurs:
