Has anyone got envers (http://www.jboss.org/files/envers/docs/index.html)
running with Tapestry5/hibernate and care to share their configuration notes?
I'm trying:
<hibernate-configuration>
<session-factory>
...
<listener class="org.hibernate.envers.event.AuditEventListener"
type="post-insert"/>
<listener class="org.hibernate.envers.event.AuditEventListener"
type="post-update"/>
<listener class="org.hibernate.envers.event.AuditEventListener"
type="post-delete"/>
<listener class="org.hibernate.envers.event.AuditEventListener"
type="pre-collection-update"/>
<listener class="org.hibernate.envers.event.AuditEventListener"
type="pre-collection-remove"/>
<listener class="org.hibernate.envers.event.AuditEventListener"
type="post-collection-recreate"/>
...
</session-factory>
</hibernate-configuration>
having previously tried:
<property name="eventListeners">
<map>
<entry key="post-insert"><bean
class="org.hibernate.envers.event.AuditEventListener"/></entry>
<entry key="post-update"><bean
class="org.hibernate.envers.event.AuditEventListener"/></entry>
<entry key="post-delete"><bean
class="org.hibernate.envers.event.AuditEventListener"/></entry>
<entry key="pre-collection-update"><bean
class="org.hibernate.envers.event.AuditEventListener"/></entry>
<entry key="pre-collection-remove"><bean
class="org.hibernate.envers.event.AuditEventListener"/></entry>
<entry key="post-collection-recreate"><bean
class="org.hibernate.envers.event.AuditEventListener"/></entry>
</map>
</property>
and variants, but end up with the same NPE at sessionfactory init:

This happens whether I annotate any of my entities with @audited or not. Would
be grateful for any pointers/gotchas, indications that envers does play nice
with Tapestry5, or even any alternative generic entity auditing facility (not
trigger based) that someone could recommend - thanks.
Regards,
Jim.
