j-interop using local credentials

Question

I'm attempting to utilize this WMI sample from the J-interop package. The issue I'm facing is that the system I'm running this against is not a part of the domain. I looked at the Javadoc for j-interop and it says in org.jinterop.dcom.core.JISession that it takes the IJIAuthInfo, domain credentials, or the credentials from another session.

How do I specify credentials local to that system?

public class ServiceManager {

    private static String domainName = "";
    private static String userName="administrator";
    private static String password="";
    private static String hostIP ="127.0.0.1";
    private static final String win32_namespace = "ROOT\\CIMV2";

    private static final int STOP_SERVICE = 0;
    private static final int START_SERVICE = 1;

    private JISession dcomSession = null;
    /**
     *
     * @param args
     */
    public static void main(String[] args) {
        ServiceManager manager = new ServiceManager();
        manager.stopService(domainName, hostIP, userName, password, "MySql");//stops a service named MySql
    }
    /**
     * Starts a given service if its stopped.
     *
     * @param domainName
     * @param hostname
     * @param username
     * @param password
     * @param serviceName
     */
    public void startService(String domainName, String hostname, String username, String password, String serviceName) {
        execute(domainName, hostname, username, password, serviceName, START_SERVICE);
    }
    /**
     * Stops a given service if its running.
     *
     * @param domainName

     */
    public void stopService(String domainName, String hostname, String username, String password, String serviceName) {
        execute(domainName, hostname, username, password, serviceName, STOP_SERVICE);
    }
    /**
