It is automatically doing the message.acknowledge. I've set the
DefaultMessageListenerContainer to do CLIENT_ACKNOWLEDGE as
<bean id="listenerContainer"
class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="concurrentConsumers" value="1"/>
<property name="connectionFactory" ref="jmsConnectionFactory" />
<property name="destination" ref="destination" />
<property name="messageListener" ref="jmsReceiver" />
<property name="sessionAcknowledgeModeName"
value="CLIENT_ACKNOWLEDGE"/>
<property name="receiveTimeout" value="-1"/>
</bean>
