Hi try this..

Code:

public static void main(String[] args) {
SessionFactory sessionFactory;
//configfile stored in src folder.. 
String configFile="/hibernate.cfg.xml";
Configuration configuration = new Configuration();
configuration.configure(configFile);
sessionFactory = configuration.buildSessionFactory();
Session s= sessionFactory.openSession()
Transaction tx = s.beginTransaction();
//hibernate action...
tx.commit;
}
