I am trying first hibernate application from tutorial. It works for hibernate 2.0 but it doest not work with hibernate 3.0.

private List listEvents() {
Session session = HibernateUtil.currentSession();
Transaction tx = session.beginTransaction();

List result = session.createQuery("from Event").list();

tx.commit();
session.close();

}

It is throwing following exception.

It's hard to say, as you don't provide the actual line number that it is failing on. But, from the looks of things, you probably don't have a required jar file in your classpath.
