I am using Hibernate 2.03 and when I use the following code the objects are not being persisted. I have read the docs and this seems to be the way it should be done.

There is no exception. The mapping and log are below. Please assist

public void updateww(List wwscores) throws HibernateException{
Session s = null;
Transaction tx = null;
try{
s = Data.getInstance().getSession();
tx = s.beginTransaction();

for (int i = 0; i < wwscores.size(); i++) {

IWWScore score = (IWWScore)wwscores.get(i);
Wwscore wwscore = (Wwscore) s.load(Wwscore.class, score.getAppno());
boolean saved = false;
if (wwscore == null){
saved = true;
wwscore = new Wwscore();
wwscore.setAppno(score.getAppno());
}
wwscore.setWwone(score.getWwone());
wwscore.setWwtwo(score.getWwtwo());
wwscore.setWwthree(score.getWwthree());
wwscore.setWwfour(score.getWwfour());
wwscore.setWwfive(score.getWwfive());
wwscore.setWwsix(score.getWwsix());
wwscore.setWwseven(score.getWwseven());
wwscore.setWweight(score.getWweight());
wwscore.setWwsummary(score.getWwsummary());
if (saved)
s.update(wwscore);
else
s.save(wwscore);
logger.info("Update of Candidate " + wwscore.getAppno());
}
tx.commit();
}catch (HibernateException e){
logException(logger, e, BaseDAO.LOG_ERROR);
if (tx != null){
tx.rollback();
}
throw e;
}finally{
s.close();
}
}

anyone listening?

From the session.load javadoc




Will always log "Update of Candidate " + wwscore.getAppno() because of {} missing.

If you load an object from a session, you don't have to call session.update. Hibernate knows when it is updated and will flush it.

Try this kind of code

I used find no problems there but there is no update to the objects state which was the problem that I was having. There are no errors. As you can see from the log it sees 0 updates

Do you update with different values ?
I saw in your first logs that null values are retruned by DB.

I'm not sure of me but Hibernate don't update your object if no real / different update is done.

Sorry for wasting your time, this is working fine the problem was on the struts side and the fact that the values coming back were exactly the same.

Thanks for the help
