[Hibernate] Re: Hibernate vs. Castor example

[Dave J. <sno...@nc...>]

In the Hibernate implementation of the DAO, I implement the 
removeNewsfeed method shown below. Why is the call to ses.load()
necessary?

- Dave


   public void removeNewsfeed( Newsfeed feed ) throws DAOException {
     removeObject( ag.Newsfeed.class, feed.getId(), feed );
   }

   private void removeObject( Class clazz, String id, Object obj )
     throws DAOException {
     Session ses = null;
     try {
       ses = sessionFactory.openSession();
       obj = ses.load(clazz,id);
       ses.delete(obj);
       ses.flush();
       ses.connection().commit();
     }
     catch (Exception e) {
       try { ses.connection().rollback(); }
       catch (Exception ex) { e.printStackTrace(); };
       throw new DAOException(e);
     }
     finally {
       try { ses.close(); }
       catch (Exception ex) { ex.printStackTrace(); };
     }
   }
