title: GWT and WebSocket / Push data from server to GWT client
body: <p>Is there any good library which supports WebSockets and is compatible with GWT? Ideally, the library would support WebSockets as well as a fallback for browsers which don't support WebSocket, e.g. a comet-like approach or polling.</p>
  
  <p>I'm currently using <a href="http://code.google.com/p/gwt-comet/" rel="noreferrer">GWT-Comet</a> to push data from my server to my GWT web application. However, this library is a bit broken in some aspects and it seems it's not maintained actively anymore. Thus, I'm searching for an alternative.</p>
