I couldn't save data in DB using Hibernate in WAR

When I use a simple class test (HibernateTest.java) .it works well and I can save my object in my mysql Database, but when I use it in a WAR I couldn't save my bean into Database.

this is my HibernateTest.java :

package com.live.presentation;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

import com.live.hibernate.util.HibernateUtil;
import com.liver.beans.User;
import com.live.business.UserBusiness;
import com.live.business.UserBusinessImp;
import com.live.dao.UserDao;
import com.live.dao.UserDaoMysql;

public class HibernateTest {

    private Session session;


    private void openSession(){
        SessionFactory sessionFactory=HibernateUtil.getSessionFactory();
        session = sessionFactory.openSession();
        session.beginTransaction();
    }

    private void closeSession(){
        session.getTransaction().commit();
        session.close();
    }

    public HibernateTest() {
UserBusiness userBusiness = new UserBusinessImp();
        userBusiness.add(new User("Lee", "lee@gmail.com", "pass00Z"));
    }

public static void main(String[] args) {

        new HibernateTest();
    }

}

Business layer has UserBusiness interface and UserBusinessImp class.

interface UserBusiness :

package com.liver.business;

import com.live.beans.User;

public interface UserBusiness {

    public void add(User user);
}

class UserBusinessImp :

package com.live.business;

import com.live.beans.User;
import com.live.dao.UserDao;
import com.live.dao.UserDaoMysql;

public class UserBusinessImp implements UserBusiness{

    public void add(User user) {
        UserDao userDao = new UserDaoMysql();
        userDao.insert(user);
    }

}

DAOlayer has UserDao interface and UserDaoMysql class.

interface UserDao :

package com.liver.dao;

import com.live.beans.User;

public interface UserDao {

    public void insert(User user);
}

class UserDaoMysql:

package com.live.dao;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

import com.live.hibernate.util.HibernateUtil;
import com.live.beans.User;

public class UserDaoMysql implements UserDao {

    private Session session;


    private void openSession(){
        SessionFactory sessionFactory=HibernateUtil.getSessionFactory();
        session = sessionFactory.openSession();
        session.beginTransaction();
    }

    private void closeSession(){
        session.getTransaction().commit();
        session.close();
    }

    public void insert(User user) {
        openSession();
        User p = new User(user.getName(), user.getEmail(), user.getPassword());
        session.save(p);
        System.out.println("sauvegarde reussi");
        closeSession();
    }

}

Now when I would like to save my data while click on sign up button it doesn't work.

    public void save(){

        System.out.println("name :"+name);

        UserBusiness userBusiness = new UserBusinessImp();
        userBusiness.add(new User(name, email,password));

    }

}

so when I click on sign up for save data, it throws an exception with below root cause:
