I have been assigned a project regarding Web-Services.The project is to develop a Web-Service for the P2P Radio through which client can register itself.
  P2P-Radio is a program that can distribute audio and video streams (MP3/Ogg Vorbis/NSV) over the Internet in a peer-to-peer manner.So,we want to use web-services instead of client-server set-up.I want to develop the web-service in java.
     Can anyone please tell me how to go about it?

  Thanks in Advance,
  Piyush
