This means you no longer need to define at least 1 Message Aware Listener. In fact, you no longer need to define any listeners on a Service e.g. | <service category="ServiceCat" name="ServiceName" description="Test Service"> | <actions mep="RequestResponse"> | <action name="action" class="org.jboss.soa.esb.listeners.SetPayloadAction"> | <property name="payload" value="Tom Fennelly" /> | </action> | </actions> | </service> | See the Programmers Guide for me details (page 41).
