Thank you verry much. I got it now. In the example the message passed by quartz component is published to the topic. So in real life, some component of mine will publish the message to org.apache.servicemix.wsn.spring.PublisherComponent and gets delivered to the subscribers.
Is this dynamic way of sending/receiving messages http://servicemix.goopen.org/site/ws-notification.html I will clean up the xml files when I get time.
