Implementing an IceStorm Subscriber

An IceStorm subscriber is an Ice server application that hosts a subscriber object, and registers a proxy to this object with a Topic hosted by the IceStorm service.

The IceStorm/weather demo program provides a complete subscriber application. It’s available in all programming languages with server-side support.

Our weather station implementation takes the following steps:

  1. Obtain a proxy for the TopicManager. This is the primary IceStorm object, used by both publishers and subscribers.
  2. Create an object adapter to host our WeatherStation servant.
  3. Instantiate the servant and add the servant tot the object adapter.
  4. Subscribe to the weather topic.
  5. Process report messages until shutdown.
  6. Unsubscribe from the weather topic.
