Hi,

I'am using a simple dialog that implements CRUD-functionality on one single entity. If only one user works with the datebase (mysql) there is no problem but multi-user environment is a big problem. If another user changes data the fist one doesn't see the changing. I can't believe why hibernate doesn't refresh the data. Before showing it to the user. I'm creating a new Session (HibernateDAOFactory instantiate...(xxx.class)) and start a new transaction. I even tried so run dao.getSession().refresh(e) for every result of the received list from the findByCriteria(). Only if I completely reconnect to the database which means closing / starting the program shows up the "correct" data from the database. Does anybody know the reason for thus behaviour? Any hint would by nice. Thanks a lot.

Jonny

Hi,

I am totally frustrated. I can't understand what's happening there. Even if I use

Code:

      HibernateUtil.shutdown();
      org.hibernate.Session s = HibernateUtil.getSessionFactory().getCurrentSession();
      
      s.beginTransaction();

      Criteria crit = s.createCriteria(Rooms.class);
      List<Zimmer> res = new LinkedList<Rooms>();
      res = crit.list();
      for (Room r : res) {
         s.refresh(r);
      }
      s.close();
      return res;

I'll get the f.... wrong (not current) data from the db. I also disabled the 2nd level cache. I don't know what to do. PLEASE any hint may help. THANKS

Jonny
