configuration: hiberante events in seam

[mars1412]

I am trying to create some eventlisteners for hibernate:
http://www.hibernate.org/hib_docs/reference/en/html/events.html#objectstate-events
but my listeners seem not to fire.

I think, it's just a configuration issue.

I created a simple listener, by overriding the default hibernate update event listener:

public class HibernateUpdateEventListener extends DefaultUpdateEventListener {
 @Override
 public void onSaveOrUpdate(SaveOrUpdateEvent event) {
 System.err.println("update-event listener fired");

 super.onSaveOrUpdate(event);
 }

}

the configuration in my hibernate.cfg.xml file:

<event type="update">
 <listener class="com.twentyfouract.web.session.util.HibernateUpdateEventListener"/>
 </event>

this file will be located in my.ear/my.jar/hibernate.cfg.xml (in the same direcotry, as the seam.properties file)

• is this the correct place fo the hibernate.cfg.xml file?
  
• do I need some other configuration?
  When I now call update() in my EntityHome class, I expect the message to be written to stderr, which does not happen...

Ask on the hibernate forum.

ok, I'll try:

The examples/wiki/codebase uses custom hibernate listeners. You are extending the wrong listener superclass.

thanx, that works, but I still don't understand why the hibernate-config does not work:

I thought, the following 2 configurations should do the same:

persistence.xml - works

 <property name="hibernate.ejb.event.post-insert"
 value="com.twentyfouract.web.session.util.HistoryInsertEventListener"/>

hibernate.cfg.xml - does not work

 <event type="post-insert">
 <listener class="com.twentyfouract.web.session.util.HistoryInsertEventListener" />
 </event>

any ideas?
