Page Created : CXF : DOSGi Discovery Demo page

DOSGi Discovery Demo page has been created by David Bosschaert (Jun 08, 2009).

Content:

This page describes the demo that shows the Discovery functionality of Distributed OSGi.

It assumes that you have set up your DOSGi/ZooKeeper based Discovery system as outlined in DOSGi Discovery.

Demo design

This demo contains of a display controller node that writes messages on all the available display instances. Display instances are realized as remote OSGi services, which are registered with the ZooKeeper-based Discovery system. The discovery system informs the controller, which is a consumer of the DisplayService, of any available remote instances of this service.

As with most of the other demos, the actual implementation consists of 3 bundles.

  • A DisplayService interface bundle.
  • A DisplayService implementation bundle.
  • A DisplayService client bundle, which takes the role of the display controller.

The Display Service interface is like this:

public interface DisplayService {
    boolean displayText(String text);
    String getID();
}
