jmsRouter reply problem

[cammette]

hi
i want to use jmsRouter to invoke another esb service in a jboss esb ,and reply the message.
jmsRouter config:

<action name="routeToReplyQueue" class="org.jboss.soa.esb.actions.routing.JMSRouter">
 <property name="jndi-URL" value="127.0.0.1:1099" />
 <property name="connection-factory" value="ConnectionFactory" />
 <property name="jndiName" value="queue/testjmsgw" />
 <property name="unwrap" value="true" />
 <property name="security-principal" value="guest" />
 <property name="security-credential" value="guest" />
 </action>

another esb service:

<service category="esbCategory" description="esb test" name="testjms">
 <listeners>
 <jms-listener busidref="test_jms" name="test_jms" />
 <jms-listener busidref="testgw_jms" name="testgw_jms"
 is-gateway="true" />
 </listeners>
 <actions>
 <action name="printMessage" class="com.test.service.invoke.TestRouter">
 </action>
 </actions>
 </service>

invoke successfule,but i can't reply the message.
