The logical flow of the program is:

1. The JMSClient, through ActiveMQConnectionFactory, connects to the topic , named "demo.org.servicemix.source" and sends a text message containing the message.soap file.
2. myComponent, being a subscriber of the topic "demo.org.servicemix.source," receives the message.
3. The myComponent implementation class, JmsServiceComponent, sends the message over the ServiceMix bus to the PxeBpelEngine by executing its onMessage() method. The destinationService property defines the destination of the message. Note: the destinationService property is found in the servicemix.xml file.
4. PxeBpelEngine sends a response back to myComponent through the ServiceMix bus, the NMR.
5. myComponent uses the jmsTemplate bean to publish the message.
6. jmsTemplate uses the jmsFactory bean to get a connection to the port associated with the JMS topic called "demo.org.servicemix.source." The message is published on the "demo.org.servicemix.source" topic.
7. JMSClient being a subscriber of topic "demo.org.servicemix.source," receives the message.
8. The response is printed on the console.
