HTTP Error 407 Proxy authentication required

[ckarun...@gmail.com]

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.

Actually, no. HTTP-Basic-Authentication has nothing to do with
Proxy-Authentication

Is the Proxy a Windows based one? If yes, it might only
accepts NTLM-authentications that aren't supported by all
Java versions.
