javacv throws java.lang.UnsatisfiedLinkError

[GoogleCodeExporter]

I have created a new netbeans project, included all jars (javacpp.jar, 
javacv.jar, javacv-*.jar), also copied all dlls from javacv-windows-x86.jar to 
c:\windows\system32; my simple java class looks like the following:

    public static void main(String[] args)  throws Exception {
        try{
            // Preload the opencv_objdetect module to work around a known bug.
        Loader.load(opencv_objdetect.class);
        // OpenCVFrameGrabber uses opencv_highgui, but other more versatile FrameGrabbers
        // include DC1394FrameGrabber, FlyCaptureFrameGrabber, OpenKinectFrameGrabber,
        // VideoInputFrameGrabber, and FFmpegFrameGrabber.
        FrameGrabber grabber = new OpenCVFrameGrabber(0);
        grabber.start();
        final IplImage image = grabber.grab();
        final BufferedImage img = image.getBufferedImage();
        ImageIO.write(img, "png", new File("out.png"));
        grabber.stop();
        }catch(Throwable t){
            t.printStackTrace();
            Thread.sleep(10000);
        }
    }

However, the program crashes with:

java.lang.UnsatisfiedLinkError:

I'm on 32-bit Windows Vista. Thanks!

I'm terribly sorry, I just read the wiki page 
http://code.google.com/p/javacv/wiki/Windows7AndOpenCV
It helped and the program works now.
Thank you!
