Hi, If we send have a value that is utf8 url encoded to the websocket:
H%C3%BCnenberg then somehow tomcat just encodes that using i think "ISO-8859-1" if we are in a filter or servlet we just do: request.setCharacterEncoding("UTF8"); and then ask for the parameter map then everything is fine it will be decoded correctly to Hünenberg problem is how do we do that in a websocket scenario? the session object of a WebSocket doesn't have anything for that as far as i can see the same goes for ServerEndpointConfig.Configurator using the modifyHandshake method.. -- Johan Compagner Servoy
