public String getWebrootUrl() {
            if (webrootUrl.length() == 0) {
                  HttpServletRequest request = FacesUtils.getRequest();
                  if (request != null) {
                        try {
                              URL reconstructedURL = new URL(request.getScheme(),
                                          request.getServerName(),
                                          request.getServerPort(),
                                          getWebroot());
                              webrootUrl = reconstructedURL.toString();
                        } catch (MalformedURLException e) {
                              webrootUrl = "";
                        }
                  }
            }
            return webrootUrl;
      }

The above code is use to generate the correct url when we were using a virtual name-based server, we've since moved off using named-based and switched to an IP based scheme so instead of returning somehting like https://www.myurl.com/ it now returns https://192.168.200.10 on our production server which is obviously a private network IP! Is there a way to get code to do a reverse-lookup on the IP in the local /etc/hosts file?

Look at InetAddress and the getHostName() method. It is supposed to do a reverse lookup for you.
