Detailed Description

This example shows how to subscribe to a device property through the pubsub API.

<blockquote>

 public void subscribeToProperty() {
   String topic = MappingService.mapPropertyToTopic(DEV_CLASS, DEV_INSTANCE, DEV_PROPERTY);
   String cycle_selector = MappingService.mapCycleSelectorToSelector(CYCLE_SELECTOR);
   try {
     subscriptionToken = sub.subscribe( topic, this, cycle_selector);
   } catch(javax.jms.JMSException je) {
     je.printStackTrace();
   } catch (javax.naming.NamingException ne) {
     ne.printStackTrace();
   }
 }
