→2. Implement the Service Provider
=== 2. Implement the Service Provider ===
'''2.1. Create the provider bundle'''
: The process of creating the bundle is almost the same as interface bundle. Here we just need an activator to register the bundle. So, when creating the new plug-in project, make sure to leave the Activator checked:

'''2.2. Register the service in the class Activator'''
: Here is the implementation of the Activator class for registering the service:

'''2.2. Define the MANIFEST.MF for the service provider bundle.'''
: In the manifest that is created during the process of creating the bundle, we need to import the service package.
: Click on the ''MANIFEST.MF'' - > select the ''Dependencies'' tab -> click on ''Add'' to ''import'' a package:

: Type in the name of the package of your interface. After it was selected click ok:

'''2.3. Install and run the Service Provider Bundle'''
: Right click on ''MAINFEST.MF'' of the ''Provider'', and go to ''Run A - > Run Configuration''
: Right click on ''OSGI Framework'' and click on ''New''.
: In the ''Workspace'', check the interface bundle and the provider bundle.
: Uncheck the ''Target Platform'' and click on ''Add Required Bundles'', then check the ''Only show selected''.
