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

Since this server isn't part of a domain it is its own domain and the domainName string needs to be set to the server name. The password should be set to the local Administrator account's password. From there you should be able to get a session authenticated.
