Java Question

Websocket getting remote IP on connect

Can I get remote IP address inside

@OnOpen

method of

@ServletEndpoint

class?
I tried follow this Accessing HttpSession from HttpServletRequest in a Web Socket @SocketEndpoint but as in Websocket - httpSession returns null it doesn't work.

Anyway I only need clients IP address.

The JSR-356 Websocket specification does not expose client IP address.
