[Hibernate] Manage the easy example

Previously I posted a easy hibernate mapping.
Here is the example manager class for this and a testcase main

The manager java class:
package hibernate.databaseTables;

import hibernate.HibernateSessionFactory;
import java.sql.Date;
import java.util.Iterator;
import java.util.List;
import org.apache.log4j.Logger;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;

public class UserManager {
    private Logger log;

    public UserManager(){
       log = Logger.getLogger(this.getClass());
    }

    public UserValue createUser(UserValue user) {
       log.info("creating User");
       Session session = HibernateSessionFactory.currentSession();
       Transaction tx = session.beginTransaction();
       Integer id = (Integer) session.save(user);
       user.setuserid(id);
       tx.commit();
       HibernateSessionFactory.closeSession();
       return user;
    }

    public void updateUser(UserValue user) {
       log.info("updating User");
       Session session = HibernateSessionFactory.currentSession();
       Transaction tx = session.beginTransaction();
       UserValue dbuser = (UserValue) session.get(UserValue.class, user.getuserid());

       if (user != null) {
          dbuser.setusername(user.getusername());
          dbuser.setpassword(user.getpassword());
          dbuser.setsurname(user.getsurname());
          dbuser.setfirstname(user.getfirstname());
          dbuser.setsex(user.getsex());
          dbuser.setaddress(user.getaddress());
          dbuser.setzipcode(user.getzipcode());
          dbuser.setcity(user.getcity());
          dbuser.setemail(user.getemail());
          dbuser.setphone(user.getphone());
          dbuser.setmobile(user.getmobile());
          dbuser.setdateofbirth(user.getdateofbirth());
       }
       session.flush();
       tx.commit();
       HibernateSessionFactory.closeSession();
    }

    public void listUser() {
       log.info("list User");
       Session session = HibernateSessionFactory.currentSession();
       Transaction tx = session.beginTransaction();
       List UsersList = session.createQuery("from UserValue").list();
       for (Iterator iter = UsersList.iterator(); iter.hasNext();) {
          UserValue user = (UserValue) iter.next();
          System.out.println("Id " + user.getuserid() + " Name " + user.getusername());
       }
       tx.commit();
       HibernateSessionFactory.closeSession();
    }

    public void tc_UserManager(){
       // testcase to create a user to the DB
       UserValue user=new UserValue();
       user.setaddress("tiensestraat");
       user.setcity("zichem");
       user.setdateofbirth(new Date(0));
       user.setemail("nico.beylemans@gmail.com");
       user.setfirstname("nico");
       user.setmobile("0478/540878");
       user.setpassword("eenwachtwoord");
       user.setphone("geen");
       user.setsex(false);
       user.setsurname("beylemans");
       user.setusername("beyle");
       user.setzipcode(3271);
       try{
          user=this.createUser(user);
          this.listUser();
       } catch (HibernateException e) {
          // problem with Hibernate happened
          e.printStackTrace();
       }
       System.out.println("primary key is " + user.getuserid());
    }
}

The main testcase class:
package hibernate;

import hibernate.databaseTables.ApplicationManager;
import hibernate.databaseTables.PermissionManager;
import hibernate.databaseTables.RoleManager;
import hibernate.databaseTables.TariffTypeManager;
import hibernate.databaseTables.UserManager;
import hibernate.databaseTables.UserRoleManager;

public class TestAsApplication {
   public static void main(String[] args) {
       // Testcases
       //testing UserManager OK
       UserManager usermanager=new UserManager();
       usermanager.tc_UserManager();
    }
}
