How to do Website Authentication in Java Applet?

You can achieve it by making an HttpURLConnection and appending username and password with the URL. As:

URL myURL = new URL("http://192.168.1.2:8082/index.cgi?username=user&password=");
HttpURLConnection myConnection = (HttpURLConnection) myURL.openConnection();
myConnection.setDoOutput(false);
int status = ((HttpURLConnection) myConnection).getResponseCode();

Alternatively (instead of appending username/password to url), you can try( not sure if it is allowed in Applet) setting the default authenticator for http requests like this:

Authenticator.setDefault (new Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication ("username", "password".toCharArray());
    }
});

You can also use Apache HttpComponents HttpClient which is very easy to use. To know more about how HTTP requests work in Java, see this answer.
