After downloading the “Eclipse classic” from Eclipse then proceed with the following steps to create Chat Program with OSGi.

The first step is to create the Chat Interface which is the Service Provider in the Program. This defines and provides the services available and the requirements and outcomes for those services.

Define the service interface

a) Create a new Plug-in Project

c) Be sure to uncheck the “Generate an activator” option as you will not be needing an activator then go ahead and click finish.
