Hi France,
I can confirm that for using websocket you'll have to write some Java code. That's what we've done for creating a Jetty Connector that is able to accept websocket connections from HTML5 apps running inside browsers.
Then we interact from inside XQuery by using the mechanism of Java Bindings [1] when we have to send out messages.

We used Jetty package that comes with Basex just adding [2] to the lib folder.
The only caveat we stumbled upon is, hope I'm recalling the right story here, that it's not possible to just add a new Connector to the jetty.xml file because BaseX ignores every connector but the first one [3] (I ask Christian to possibly confirm or confute this). Thus we needed to configure the Jetty connector from inside the Java code which is not optimal for us but works.

Hope this helps.
Ciao,
Marco.

Has anyone implemented a solutions that uses web sockets with BaseX? I've been doing some work with socket.io and node.js, but all the research I've done on Jetty points to the need to create .java files that manage the connection on the server side. Does that mean I'd need a BaseX module to manage that? Since Jetty seems to support web sockets, do you forsee any other issues specific to BaseX?
