Hi Sabra, AFAIK you don't have to do any extra configurations to make websocket works with AS. This kind of issues may pop out when webapp contains websoket jars inside the webapp itself (WEB-INF/lib). IF not most probably there is some mismatch in the actual websocket that get deployed and what you are trying to connect.
