I have placed all hibernate related jars in Jboss/server/standard/lib folder

My method which opens the session is as follows

public static int insertRecords(){
		int success=0;
		Configuration cfg =null;
		SessionFactory sessionFactory=null;
		Session session = null; 
		try{
		 sessionFactory = new AnnotationConfiguration()
         .configure("hibernate.cfg.xml").buildSessionFactory();
		//sessionFactory=cfg.buildSessionFactory();
			session =sessionFactory.openSession();
				System.out.println("Test5");
				Transaction tx = session.beginTransaction();
				System.out.println("Test6"+tx);
				System.out.println("Inserting Record");
				TO_DEBUG user = new TO_DEBUG();
				user.setSLNO(1);
				user.setV1("Sample testing for hibernate1");
				user.setV2("Sample testing for hibernate2");
				user.setV3("Sample testing for hibernate3");
				user.setV4("Sample testing for hibernate4");
				user.setVL("Sample testing for hibernateVL");
				session.save(user);
				success=1;
				tx.commit();
		}catch (Exception e) {
			e.printStackTrace();
			// TODO: handle exception
		}finally{
			if(session!=null){
				session.flush();
				session.close();
			}
		}
		return success;
	}

Thanks,
Shyam.
