Start and Stop a Windows Service From Java

Question

Is there any way to start and stop a Windows service from Java? The only post I found on it (http://forum.java.sun.com/thread.jspa?threadID=647509) had a link to one of the many aps that allow Java programs to be services, which is not what I am interested in doing.
I am attempting to get data from performance counters from the Windows Performance Monitor into a Java ap without using JNI. I can get the data from C++ or a .net language pretty easily and was going to create a service that would listen for socket requests and feed back the data. However, I'd like to start and stop that service when my java code starts and stops. Is this possible? Would it make more sense to just use a .exe and Runtime.exec()?

If it's only to start or stop a service then you could use the net command without any need for JNI.import java.io.*;
public class MsWinSvc {
    static final String CMD_START = "cmd /c net start \"";
    static final String CMD_STOP = "cmd /c net stop \"";
    public static int startService(String serviceName) throws Exception {
        return execCmd(CMD_START + serviceName + "\"");
    public static int stopService(String serviceName) throws Exception {
        return execCmd(CMD_STOP + serviceName + "\"");
    static int execCmd(String cmdLine) throws Exception {
        Process process = Runtime.getRuntime().exec(cmdLine);
        StreamPumper outPumper = new StreamPumper(process.getInputStream(), System.out);
        StreamPumper errPumper = new StreamPumper(process.getErrorStream(), System.err);
        outPumper.start();
        errPumper.start();
        process.waitFor();
        outPumper.join();
        errPumper.join();
        return process.exitValue();
    static class StreamPumper extends Thread {       
        private InputStream is;
        private PrintStream os;
        public StreamPumper(InputStream is, PrintStream os) {
            this.is = is;
            this.os = os;
        public void run() {
            try {
                BufferedReader br = new BufferedReader(new InputStreamReader(is));
                String line;
                while ((line = br.readLine()) != null)
                    os.println(line);
            catch (Exception e) {
                e.printStackTrace();
}Regards
