How to stop/start spring DefaultMessageListenerContainer?

I have developed project using Spring JMS to receive the message from Queue. and it is deployed Websphere application Server (WAS 7.5) clustered environment. it is working fine once it is deployed in server.Later i have update my logger information and deployed in to server. it seems server not picking the latest code base. Even though i have stop/start the cluster.

Please refer below config xml.

<bean id="connectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory">
            <property name="hostName" value="${hostName}"/>
            <property name="port" value="${port}"/>
            <property name="queueManager" value="${queueManager}"/>
            <property name="transportType" value="${transportType}"/>
            <property name="channel" value="${channel}"/> 
   </bean>

   <jms:listener-container container-type="default"
connection-factory="connectionFactory" acknowledge="auto" concurrency="5" >
<jms:listener destination="DEV.TESTQUEUE" ref="jmsMessageListener" 
</jms:listener-container>

 <bean id="jmsMessageListener" class="JmsMessageListener"/>


      public class JmsMessageListener implements MessageListener { 

    public void onMessage(Message message) {

      }
    }

Could you please advise how to stop/start the container?
