Unable to navigate through HTTP Proxy using HtmlUnitDriver

FcoSandoval
Hi all,

I'm using Selenuim with HtmlUnitDriver for navigating and downloading a file from a site. It works fine when I hit directly ti the site from my machine, but when I do through a Http proxy, I cannot get connected to the site... If I look at log file it hangs making the connection to timeout:

It seems that the proxy is not set.
I've tried everything found in the net to configure the proxy, but no success. My code for creating the WebDriver is:

    private WebDriver createWebDriver() {

        

        boolean useProxy = true;

        Proxy proxy = useProxy ? new Proxy() : null;


        DesiredCapabilities capability = DesiredCapabilities.htmlUnit();

        capability.setJavascriptEnabled(true);


        // Chequea si debe configurar un proxy de salida a internet, si es que está configurado

        if ( useProxy ) {

            String proxySettings = PROXY_HOST + ":" + PROXY_PORT;

            proxy.setProxyType(ProxyType.MANUAL);            

            proxy.setHttpProxy(proxySettings).setSslProxy(proxySettings);

            capability.setCapability(CapabilityType.PROXY, proxy);

            capability.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);

            capability.setCapability(CapabilityType.ACCEPT_INSECURE_CERTS, true);

        }


        HtmlUnitDriver driver = new HtmlUnitDriver(capability) {

            

            @Override

            protected WebClient modifyWebClient(WebClient client) {

                

                // Configura que no se aborte la ejecución de la página por errores de JavaScript

                client.getOptions().setThrowExceptionOnScriptError(false);

                LOGGER.debug("modifyWebClient -> isThrowExceptionOnScriptError: {}", client.getOptions().isThrowExceptionOnScriptError());


                // Chequea si debe configurar un proxy de salida a internet, si es que está configurado

                if ( useProxy ) {

                    ProxyConfig proxyConfig = new ProxyConfig(PROXY_HOSTPROXY_PORT);

                    proxyConfig.setSocksProxy(false);

                    client.getOptions().setUseInsecureSSL(true);

                    client.getOptions().setProxyConfig(proxyConfig);               

                    

                    // Agrega el provider a la instancia webClient 

                    DefaultCredentialsProvider credentialsProvider = new DefaultCredentialsProvider();

                    credentialsProvider.addCredentials("username", "password");

                    client.setCredentialsProvider(credentialsProvider);

                }

                

                // Configura handler para ventanas de confirmación que siempre acepta (retorna true)

                ConfirmHandler okHandler = new ConfirmHandler() {

                    public boolean handleConfirm(Page page, String message) {

                        return true;

                    }

                };

                client.setConfirmHandler(okHandler);


                // Configura handler para procesar respuesta de una página

                client.addWebWindowListener(new WebWindowListener() {


                    public void webWindowOpened(WebWindowEvent event) {

                    }


                    @SuppressWarnings("unchecked")

                    public void webWindowContentChanged(WebWindowEvent event) {


                        WebResponse response = event.getWebWindow().getEnclosedPage().getWebResponse();

                        try {

                            Map<String, String> headersMap = ObjectUtils.toMap(response.getResponseHeaders(), "name", "value");

                            // Si es de tipo application/octet-strem, es un archivo

                            if (response.getContentType().equals("application/octet-strem")) {                        

                                // Genera el path donde quedarán los archivos

                                String actualPath = "";

                                String downloadPath = SII_DIRECTORY;

                                if ( StringUtils.isNotNullOrEmpty(downloadPath) ) {

                                    File downloadDir = new File(downloadPath);

                                    if (!downloadDir.exists())

                                        downloadDir.mkdirs();

                                    actualPath = downloadPath + File.separator;

                                }

                                // Obtiene el nombre del archivo a bajar y lo copia

                                String contentDisposition = headersMap.get("Content-Disposition");

                                String downloadedFileName = actualPath + contentDisposition.substring(contentDisposition.indexOf('=') + 1);

                                LOGGER.debug("webWindowContentChanged -> Downloading file: {}", downloadedFileName);

                                IOUtils.copy(response.getContentAsStream(), new FileOutputStream(downloadedFileName));

                            }

                        } catch (Exception ex) {

                            LOGGER.error("webWindowContentChanged -> Exception: {}", ex.getMessage(), ex);

                        }

                    }


                    public void webWindowClosed(WebWindowEvent event) {

                    }

                });

                

                return client;

            }

          };


          // Chequea si debe configurar un proxy de salida a internet, si es que está configurado

          if ( useProxy ) {

              driver.setProxySettings(proxy);

              driver.setAcceptSslCertificates(true);

          }

          

          driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);


          driver.setJavascriptEnabled(true);

          return driver;

    }


I'll appreciate any help. Thanks.
