<syn:target>
<syn:inSequence>
<syn:property name="OUT_ONLY" value="true"/>
<syn:send>
<syn:endpoint>
<syn:address
uri="jms:/Adding?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&transport.jms.DestinationType=queue"/>
</syn:endpoint>
</syn:send>
