Oh, sorry,
I think the Audit-Interceptor must be the culprit. I had the same
problem when adding a Message-Driven thingy into one of my projects.
You'll need to define a second instance of the SessionFactory, contrary
to what I told before, like this:
<service-point id="HibernateSessionFactory" parameters-occurs="none"
interface="org.apache.hivemind.ServiceImplementationFactory">
<invoke-factory model="singleton">
<construct autowire-services="false"
class="com.javaforge.honeycomb.hivemind.hibernate.HibernateSessionFactor
y"
initialize-method="init">
<configuration>
honeycomb.hibernate.HibernateSessionFactory
</configuration>
<service>hivemind.ShutdownCoordinator</service>
<service-id/>
<set property="updateSchema"
value="false"/>
<set property="transactionManager"
value="false"/>
</construct>
</invoke-factory>
<interceptor service-id="hivemind.LoggingInterceptor"/>
</service-point>
It's important to turn off autowiring otherwise HiveMind will
auto-inject the wrong AuditInterceptor Service. Of course, if you need
auditing, you can also configure a second instance of the interceptor
and wire it up explicitly.
