hello, Stevo
    thank you very much for your prompt reply.
you have enlightened me and finally i finished my work as what i want. thanks again.
 
i'm using jms(amq5.5) with mule 3.1.2, what i want is to remove expired messages stored in amq automatically, and now my mule configuration file looks like this:
<mule ...>
<jms:activemq-connector name="jmsConnector"
  acknowledgementMode="AUTO_ACKNOWLEDGE"
  specification="1.1"
  persistentDelivery="false"
  cacheJmsSessions="true"
  connectionFactory-ref="activeMqConnectionFactory" />
 
 <spring:bean id="activeMqConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
  <spring:property name="brokerURL" value="tcp://localhost:61616" />
  <spring:property name="userName" value="system" />
  <spring:property name="password" value="manager" />
  <spring:property name="sendTimeout" value="30000" />
 </spring:bean>
 
<flow name="esbEntrance">
     <http:inbound-endpoint address="http://localhost:19090/esb/services" exchange-pattern="request-response">
        <byte-array-to-string-transformer encoding="UTF-8" />
    </http:inbound-endpoint>     
    <jms:outbound-endpoint queue="#[xpath:/flow/@id]" exchange-pattern="request-response" responseTimeout="60000" connector-ref="jmsConnector">
            <message-properties-transformer scope="outbound">
              <!-- tell amq to expire this message after some time. -->
              <add-message-property key="JMSExpiration" value="30000" />
              <add-message-property key="timeToLive" value="30000"/>
           </message-properties-transformer>
    </jms:outbound-endpoint>
 </flow>
</mule>
 
i've tested this, it seems, actually amq will remove this expired message when responseTimeout after 60 seconds yet not timeToLive which is 30 seconds
but it doesn't matter, i'll study about this further.
 
Regards,
Eric.
