Which webserver to use for hosting socket.io-java?

I am pretty new to groovy/java. I would like to host a socket.io-java server (https://github.com/tadglines/Socket.IO-Java).

In python I used gevent (https://bitbucket开发者_Go百科.org/Jeffrey/gevent-socketio) to host a similar service since it provides an efficient no-blocking io event loop.

Which container in the java world provides such event loop and is suited for the job?

Thanks

I am looking at the pom
Looks like you might want to start with jetty?
