title: Java server and socket.io
body: <p>Are there any examples(ready scripts) to connect to java server with socket.io library?
  My problem: I have a server that works on java (proceed some data from clients) and a java client that is always connected to server (server is to be informed when a client is disconnected).
  I want to create a javascript extension for google chrome that replace this java client.
  But now server and client communicate now with simple text protocol.</p>
