I am trying to download facebook profile picture using java.But getting error

Question

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.Authenticator;
import java.net.PasswordAuthentication;
import java.net.URL;

public class SaveImageFromUrl {

    public static void main(String[] args) throws Exception {

        // proxy settings
        System.setProperty("http.proxyHost", "porxyHost");
        System.setProperty("http.proxyPort", "8080");
        Authenticator authenticator = new Authenticator() {
             public PasswordAuthentication getPasswordAuthentication() {
            return (new PasswordAuthentication("userxyz","password".toCharArray()));
            }
        };
        Authenticator.setDefault(authenticator);

        String imageUrl = "https://graph.facebook.com/10000012233xxxx/picture";
        String destinationFile = "D://image4.jpg";

        saveImage(imageUrl, destinationFile);
    }

    public static void saveImage(String imageUrl, String destinationFile) throws IOException {
        URL url = new URL(imageUrl);
        InputStream is = url.openStream();
        OutputStream os = new FileOutputStream(destinationFile);

        byte[] b = new byte[2048];
        int length;

        while ((length = is.read(b)) != -1) {
            os.write(b, 0, length);
        }

        is.close();
        os.close();
    }

}

My code works fine and downloads image for other imageurl paths.But it is not working when I use String imageUrl = "https://graph.facebook.com/10000012233xxxx/picture";

I am getting the following error :

You need to make sure that your application can follow redirects, because Facebook is sending one if you request

/{user_id}/picture

To implement this, have a look at http://www.mkyong.com/java/java-httpurlconnection-follow-redirect-example/

Also, try setting the Proxy authentication like this:

System.setProperty( "http.proxyUserName", "username" );
System.setProperty( "http.proxyPassword", "password" );

I suspect you get the timeout from your proxy connection, but you should be able to test this yourself.

Updated my answer. Check that the timeout is not from your proxy! – Tobi May 08 '14 at 05:57
NO ITS NOT FROM MY PROXY – Sagar Bhosale May 08 '14 at 12:07
THEN I DON'T KNOW! I guess you need to put in some effort yourself and test it one by one. I'm out. – Tobi May 08 '14 at 13:13
