Solved it. I was uploading exported jar instead of the bundle which gets generated in /generated folder.
Regarding approach, I found it working. I have blogged about my PoC here: https://exploringsoftwareworld.blogspot.in/2018/02/osgi-plugin-framework-using-http.html Hope it helps people in future. Can we use it for the demo of HTTP whiteboard on the enroute site? ( http://enroute.osgi.org/services/org.osgi.service.http.whiteboard.html).
