Implement the Chat Provider

Register the service in the class Activator

a) Create a new Plug-in Project
b) Name your Plug-in Project (cs.dps914.osgi.lab.provider) again be sure to select the target platform correctly
c) This time you can leave the Activator checked as you will need it. (Change the name of the activator to cs.dps914.osgi.lab.provider.ChatActivator)
