#24463 — HTTP Error 407 Proxy authentication required

I am trying to access the url by using this code

System.setProperty("http.proxyHost", "111.88.15.108");
    System.setProperty("http.proxyPort", "8002");
    System.setProperty("http.proxyUser", "user");
    System.setProperty("http.proxyPassword", "password");
    URL oracle = new URL("http://www.google.com/");
    URLConnection yc = oracle.openConnection();
    BufferedReader in = new BufferedReader(new InputStreamReader(
            yc.getInputStream()));
    String inputLine;
    while ((inputLine = in.readLine()) != null)

        System.out.println(inputLine);
    in.close();

This is working fine in my window machine but this is not working in linux machine. i am getting eror like this

    Exception in thread "main" java.io.IOException: Server returned HTTP response code: 407 for URL: http://www.google.com/ at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at com.yahoo.Connection.main(Connection.java:31)

Even proxy settings are correct and i tried like this also

java -Dhttp.proxyHost="111.88.15.108" -Dhttp.proxyPort="8002" -Dhttp.proxyUser="user" -Dhttp.proxyPassword="password"  -jar yahoo_test3.jar

But Same Error and i tried to set the export http_proxy= in /etc/profile but no use

Any idea where it is going wrong.

I believe you you need to use a java.net.Authenticator, something like

    // PROXY
    System.setProperty("http.proxyHost","proxy.mydomain.local") ;
    System.setProperty("http.proxyPort", "80") ;
 
    Authenticator.setDefault(new Authenticator() {
      protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication
              ("mydomain\\username","password".toCharArray());
    }});

Bye.
