how can I integrate my existing web application running on application server(i.e.JBOSS) with node.js?

I have an existing web application running on Application server, which is basically a form designing module build on JSF 2.0. Now I want to achieve a real time collaboration, like on one client one user perform an operation, should be visible to connected clients. I want to broadcast the event performed on a client to connected clients. I want to use Node.js to push the messages to the clients but as per my requirement how can I integrate existing web application with node.js, as I have to listen the event source from node.js and an existing connection also required with node.js on a different port. I am new to node.js, this is the first application i will build on node.js if possible. Kindly suggest.

Thanks in advance.

you can use node to run a socket.io server which will let the client communicate bi-directionally with the server. So long as every client connects to the same socket.io server it will seamlessly integrate with your existing application.
