    Lightbulb Connect Java app thru proxy with authentification

    I have a java app that has to connect thru a proxy to some addresses This is what I've tried
    final String authUser = "xxx";
    final String authPassword = "xxx";
    Authenticator.setDefault(
    new Authenticator(){
       public PasswordAuthentication getPasswordauthentication(){
           return new PasswordAuthentication(
           authUser, authPassword.toCharArray());
       }
    });
     
    System.setProperty("http.proxyUser", authUser);
    System.setProperty("http.proxyPassword",authPassword);
    System.setProperty("http.proxyHost","xxx");
    System.setProperty("http.proxyPort","8080");

    After I run the program it gives me this error:

    java.net.ConnectException: Connection refused: connect

    Is it correct how I tried to connect through the proxy and authenticate?

    Any Help is appreciated!
