The method getRequestedSessionId (and isRequestedSessionIdValid) is declared on the HttpServletRequest interface. You're trying to invoke the method on a reference of type ServletRequest. If you know the referenced object will really be a HttpServletRequest, cast it in order to invoke the method.

HttpServletRequest httpRequest = (HttpServletRequest) request;
if (httpRequest.getRequestedSessionId() != null && !httpRequest.isRequestedSessionIdValid()) {...
