还是不能运行
Ins.jsp这个页面可以填写表单，但是提交表单就出错，下面语句有问题

你的事务开启有问题
一般是这样写：
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction tx= session.beginTransaction();
session.save(user1);
tx.commit();
session.close();
sessionFactory.close();

Session session = sessionFactory.openSession();
Transaction tx= session.beginTransaction();
session.save(user1);
tx.commit();
session.close();
sessionFactory.close();

Hsession他是什么没看见定义啊！
beginTransaction是方法吧！！
