accessing a password protected URL

Question

I'm trying to access a url that needs authentication by a username and password.

There is no errors when building.. Am I missing anything?

this is the first class, it sets the authenticator that will be used by the networking code

 public class AccessPasswordProtectedURLWithAuthenticator {

  public static void main(String[] args) {

    try {

        // when a proxy or an HTTP server asks for authentication.

        Authenticator.setDefault(new Authenticator(){});

        URL url = new URL("http://website.html");

        // read text returned by server
        BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

        String line;
        while ((line = in.readLine()) != null) {
            System.out.println(line);
        }
        in.close();

    } catch (MalformedURLException e) {
        System.out.println("Malformed URL: " + e.getMessage());
    } catch (IOException e) {
        System.out.println("I/O Error: " + e.getMessage());

    }

}

}

the second class

 public class CustomAuthenticator extends Authenticator{

  /// Called when password authorization is needed

    protected PasswordAuthentication getPasswordAuthentication() {

       /// Get information about the request

        String prompt = getRequestingPrompt();
        String hostname = getRequestingHost();
        InetAddress ipaddr = getRequestingSite();
        int port = getRequestingPort();

        String username = "Administrator";

        String password = "Administrator";

        /// Return the information (a data holder that is used by Authenticator)

        return new PasswordAuthentication(username, password.toCharArray());

    }

}

Answer 1

Your first code segment doesn't reference the second class. It should have this code:

Authenticator.setDefault(new CustomAuthenticator());

Answer 2

Have you tried prepending the username and password to the hostname in the URL itself? This may allow you to avoid using the Authenticator altogether:

URL url = new URL("http://username:[email protected]");
