You can add an Authenticator to your Java client:

    static class BasicAuthenticator extends Authenticator {
        String baName;
        String baPassword;
        private BasicAuthenticator(String baName1, String baPassword1) {
            baName = baName1;
            baPassword = baPassword1;
        }
        @Override
            public PasswordAuthentication getPasswordAuthentication() {
                System.out.println("Authenticating...");
                return new PasswordAuthentication(baName, baPassword.toCharArray());
            }
    };           

The Authenticator requires these imports:

import java.net.Authenticator;
import java.net.PasswordAuthentication;

Class description: Authenticator

Then you can set the default Authenticator to an instance of your Authenticator:

        String name = "domain\\name";
        String password = "password";
        Authenticator.setDefault(new BasicAuthenticator(name, password));

A dialog or some other method is of course preferable to hard-coded Strings for the name and password. But this is just an example to show how it can be done. Username and passwords should be secured and configurable.

When you send an HTTP message, the Authenticator negotiates the credentials.
