Basic Authentication usung URLConnection in java

[Joe Harry]

Guys,

I have to connect to a URL which expects the caller to be authenticated using a Basic Realm authentication mechanism. When I tried connecting so, it still throws me out saying that I'm not authenticated.

Below is what I'm trying:

    public String sayHallo() {
        String userPassword = "admin" + ":" + "admin";
        String encoding = new sun.misc.BASE64Encoder().encode (userPassword.getBytes());

        URL url = null;
        try {
            url = new URL("http://localhost:8130/nucleus/dpwn/repository/MyRepository?xmltext=null");
        } catch (MalformedURLException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }
        URLConnection conn = null;
        try {
            conn = url.openConnection();
            conn.setRequestProperty ("Authorization", "Basic " + encoding);
        } catch (IOException e) {
            System.out.println("Connection Exception Occurred here ************* ");
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }

         //Basic realm="Dynamo Admin Server"
        System.out.println("The URLConnection obtained is ******************************* " + conn);
        System.out.println("The ContentEncoding is ********************   " + conn.getContentEncoding());
        System.out.println("The ContentEncoding is ********************   " + conn.getURL());
        String headerName ="abc";
        for (int i=0;;i++) {
            headerName = conn.getHeaderFieldKey(i);
            String headerValue = conn.getHeaderField(i);
            System.out.println("The values read are  ********************** " + headerName + " = " + headerValue + "  ********************");
        }
