I have been working on a video chat application using `WebRTC` and using `Java Websocket` as a Signalling server. 

This application is working successfully on `Tomcat`.

Currently I am using​ Google's STUN server.

>  "stun:stun.l.google.com:19302"}]}; var pc = new
>  RTCPeerConnection(pc\_config);

I don't want to relay on a public or 3rd party STUN server, like above.

Since my application will be published to public Tomcat server with dedicated domain. I want use/setup my own STUN or TURN server.

Can I do that with Tomcat?  

Are there any stable open-source libraries available for this? 

Please point me to an example if any such.
