Found the answer to my own question by finding this:
http://www.massapi.com/source/github/20/06/200618196/guacamole/src/main/java/org/glyptodon/guacamole/net/basic/websocket/BasicGuacamoleWebSocketTunnelEndpoint.java.html
So all I needed to do was add the subprotocols = {"guacamole"} value to the
@ServerEndPoint anotation.
