I am having problems when i register event listeners programatically, i have extended the SaveorUpdateListener and i register programatically with the following code:

Configuration configuration = new Configuration();
sessionFactory = configuration.configure().buildSessionFactory();
configuration.getSessionEventListenerConfig().setSaveOrUpdateEventListener(new SaveOrUpdateEventListenerImpl());

Now when the statement saveOrUpdate is called, only the defualt listeners are called, i fail to fathom what am i missing. Can anyone please help me out here.

The Alternate was to add the tag in hibernate.cfg of :
<listener type="SaveOrUpdate" class="SaveOrUpdateEventListenerImpl"/>
but application crashes giving error :

i would appreciate if anyone could help me out in this problem especially in registering programaticaly as well as through cfg xml file. Thank You.

the crashing problem was resolved by replacing SaveOrUpdate by save-update but the Binding problem still existed, When saveorUpdate was called, again only the default listener was called instead of my custom listeners, please anyone who can help me out that i cant seem to bind my custom built listeners to application, everytime default listeners are being invoked when an event is fired. What problem is in my approach.Thank You
