       public static void main(String args[])
{
    Session session=null;
    try
    {
   SessionFactory sessionFactory =new Configuration().configure().buildSessionFactory();
        session =sessionFactory.openSession();

    Contact contact=new Contact();
   contact.setFirstName("mohan");
  contact.setLastName("raddy");
  contact.setEmailId("mm@gmail.com");
    contact.setCellNo("4664564564");
   contact.setWebsite("www.stackoverflow.com");
        session.save(contact);
       session.beginTransaction().commit();
      System.out.println("done");


    }catch(Exception e)
    {
    System.out.println(e);
    }




    session.beginTransaction();
    List<Contact> contacts = null;
    try {

        contacts = (List<Contact>)session.createQuery("from Contact").list();

    } catch (HibernateException e) {
        e.printStackTrace();
        session.getTransaction().rollback();
    }
    session.getTransaction().commit();


    for (Contact contact : contacts) {
        System.out.println(contact.getFirstName());
      System.out.println(contact.getLastName());
        System.out.println(contact.getEmailId());
          System.out.println(contact.getCellNo());
            System.out.println(contact.getWebsite());
    }   
   }}
