Can I run wicket websocket in websphere application server?

I try to implement wicket 7 websocket in websphere application server 8.5.5, but the websocket fails to connect and there is error message

failed: Error during WebSocket handshake: Unexpected response code: 404.

May I know if wicket websocket works in websphere application server?
