 Post subject: persisting data with saveOrUpdate() -- question

i am using the statment block:
Code:
      
try
{
    ses.saveOrUpdate( obj );
    ses.connection().commit();
}
catch( Exception e )
{
..
}
to persist a change to an object and the save does not seem to work. I get the object as a result of one session and then do the saveOrUpdate on another session. In the mapping file, i set the unsaved-value=none to be sure an update will occur.

Any and all help is greatly appreciated.

That didn't work, the code now looks like this:
Code:
   protected void storeObject( Session ses, Object obj )
   throws DAOException
   {
      try
      {
         ses.saveOrUpdate( obj );
         ses.connection().commit();
         ses.flush();
      }
      catch( Exception e )
      {
         // if we have an exception try to roll back
         try
         {
            ses.connection().rollback();
         }
         catch( Exception ex )
         {
            CPLog.persistence.fatal( e.toString() );
         }

         ;
         throw new DAOException( e );
      }
   } // end storeObject


Something is wrong and there is nothing weird in the log file... any other thoughts?

LOL!


You flush() the session _before_ committing, obviously!


look, all this is documented in the Hibernate manual and is even the first question in the FAQ.

i have it working, what i did was modify my mapping document and removed the cascade attribute in my set collection. this probably is a hack isn't it?

yeah, i will need to figure this one out... looks like the cascade is causing issues. i will report back with my findings. Thanks for your help, i appreciate it, and next time i will try to do a bit more reading before blasting off with a question.
