You might want to investigate a Java web application server like Tomcat or Glassfish. Their latest versions have websockets support.
One thing that bothers me about websockets programming is that it is very dependent upon the availability of those APIs in both browser and server, and that limits what you can support. If you use a transport abstraction framework like Atmosphere (
https://github.com/Atmosphere/atmosphere), you can code to a neutral API and the runtime will determine the right transport to use (websockets, comet, long polling, etc.)

Subject: [WEB400] Websockets on the IBMi
Has anyone else got anything working on the IBMi with regard to websockets?
I have just completed the first phase of integrating Renaissance with a jWebsocket server on the i and so far so good. It seems to work pretty well - apart from the fact that I cannot get any life out of Safari. Also, IE doesn't support websockets until IE10, so that uses a flash-bridge instead at the moment - but that works pretty well too.
I picked jWebsocket (www.jwebsocket.org<
http://www.jwebsocket.org>) because it is written in java and therefore runs almost straight out of the box on the i - and the client-side stuff provided links nicely with jQuery. All I had to do was create my own plug-in for the server that makes use of jt400native.jar to enable data queues and direct calls.
My only concern with the jWebsocket server is that it appears to have gone quiet. No new beta versions since May this year. I am wondering if I have backed the wrong horse for my first delve into this. This is the main reason for me canvassing feedback on what other people are up to with websockets.
For anyone interested, there is a noddy demo function available at
http://rns.coraltree.co.uk on the Developers Examples and Demos menu (user id and password both "demo") that I have been using to test things. The demo is not very exciting (until you appreciate the avenues that websockets opens up for you). Most of the time the jWebsocket server is active but I occasionally shut it down while testing.
