public class HibernateUtil {
private static final SessionFactory sessionFactory=buildSessionfactory();
//private static
String path="/hibernate.cfg.xml";
public static SessionFactory buildSessionfactory()
{
try {
//URL url= HibernateUtil.class.getResource(path);
Configuration config=(Configuration) new Configuration().configure().buildSessionFactory();
return (SessionFactory) config;
} catch (Throwable e) {
// TODO Auto-generated catch block
System.out.println("Initial SessionFactory creation failed \t" +e);
