1.
connecting to ZK's websocket endpoint results in the following error message:
zk.wpd:997 WebSocket connection to 'ws://robert-nb:8080/zk-rxdemo/zkwm/?dtid=z_589' failed: Error during WebSocket handshake: Unexpected response code: 404
The endpoint configuration uses a trailing slash "/zkwm/" (should be without it "/zkwm")
2.
secondary issue happens during WebSocketEndPoint onOpen
java.lang.NullPointerException

The _httpRequest member doesn't contain the http session anymore (seems like tomcat is cleaning this up)
The _httpSession can be retrieved via (HttpSession)_session.getNativeSession()
