I am running into following issue when trying to use WebSphere datasource and transaction management. It looks like it is able to get a handle on datasource but throws the exception as seen below. I have tried everything possible I can think of including using ojdbc14.jar driver for Oracle 9i, as it helped resolve some of Oracle database issues. My datasource in websphere is configure to run as Container managed persistence. I am attaching hibernate.cfg.xml and full error log. Please provide your input as soon as possible.

Class invoking save
try {
// This step will read hibernate.cfg.xml and prepare hibernate for use
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
//Uncomment below to use websphere jdbc connection pool
Context ctx = new InitialContext();
Object obj = ctx.lookup(factoryName);
sessionFactory = (SessionFactory) obj;
session = sessionFactory.openSession();
//some code here adding the objects to parent object
session.save(objects);
}
catch(HibernateException he) {
if (transaction != null)
transaction.rollback();
throw new NavisysException(he);
}
catch(NamingException ne) {
throw new NavisysException(ne);
}
finally {

session.flush();
session.close();
}
