Video Conferencing using Java

Hi.. My name is Kris, and I am a final yr engineering student in CS. Well, I am

involved in an open source project (Using fedora). It is actually an e-learning

Program. So I have to do a module in video & audio conferencing. I am familiar with

C#.NET but I am relatively new to Eclipse and Java. I am learning the basics of

Eclipse using video tutorials, but I have no idea how to start learning the

Networking Part I mean that audio and video conferencing part.
So how or where can I find resources that can help me to complete my module...

Please help me....
