Here is the event method from my servlet that implements HttpEventServlet: public void event(HttpEvent event)     throws IOException, ServletException   {     log.info("event() entered");     HttpServletRequest request = event.getHttpServletRequest();     HttpServletResponse response = event.getHttpServletResponse();     switch (event.getType()) {       case BEGIN:         log.info("Begin for session: " + request.getSession(true).getId());         StringBuilder toLog = new StringBuilder();          Enumeration params = request.getParameterNames();         // Debug code         while(params.hasMoreElements()) {             String current = (String) params.nextElement();             toLog.append(current + "=" + request.getParameter(current));             if(params.hasMoreElements()) {                 toLog.append(", ");             }         }         log.warn("BEGIN Parameters: " + toLog.toString());         messageSender.addConnection(response);         break;       ....... the debug code produces the following output: 13:43:09,688 INFO  event() entered 13:43:09,688 INFO  Begin for session: PJG9NHvS1qi t-vJE7uDDJisF 13:43:09,688 WARN  BEGIN Parameters: message=[{"version":"1.0","minimumVersion":"0.9","channel":"/meta/handshake","id":"6","supportedConnectionTypes":["long-polling","long-polling-json-encoded","callback-polling"]}] Any help would be greatly appreciated. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/642745#642745] Start a new discussion in JBoss AS 7 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
