I am trying to configure to listener in mine persistence.xml but it is not functioning:

Here is my persistence.xml file:

<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="myapp" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/myapp</jta-data-source>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hibernate.ejb.event.pre-update" value="com.mypackage.MyAPPClassListener"/>
</properties>
</persistence-unit>
</persistence>


Parts of the MyAPPClassListener:

public class MyAPPClassListener implements PreLoadEventListener, PreInsertEventListener, PreDeleteEventListener,PreUpdateEventListener,
PostDeleteEventListener, PostInsertEventListener, PostUpdateEventListener, PostLoadEventListener{

....
public boolean onPreUpdate(PreUpdateEvent event) {
// code pre-update here...
}
....
}

helpe-me. thank you

I cannot reproduce your problem (added an explicit test case), which version are you using (please use the question template next time, it is useful)
