I am tring to use opencv and java for face detection, and in that pursit i found this "JNI2OPENCV" file....but i am confused on how to make it work, can anyone help me?

and the following is the FaceDetection.java
class JNIOpenCV {
static {
System.loadLibrary("JNI2OpenCV");
}
public native int[] detectFace(int minFaceWidth, int minFaceHeight, String cascade, String filename);
}
public class FaceDetection {
private JNIOpenCV myJNIOpenCV;
private FaceDetection myFaceDetection;
public FaceDetection() {
myJNIOpenCV = new JNIOpenCV();
String filename = "lena.jpg";
String cascade = "haarcascade_frontalface_alt.xml";
int[] detectedFaces = myJNIOpenCV.detectFace(40, 40, cascade, filename);
int numFaces = detectedFaces.length / 4;
System.out.println("numFaces = " + numFaces);
for (int i = 0; i < numFaces; i++) {
System.out.println("Face " + i + ": " + detectedFaces[4 * i + 0] + " " + detectedFaces[4 * i + 1] + " " + detectedFaces[4 * i + 2] + " " + detectedFaces[4 * i + 3]);
}
}
public static void main(String args[]) {
FaceDetection myFaceDetection = new FaceDetection();
}
}
CAn anyone tell me how can i make this work on Netbeans?? I tried Google but help on this particular topic is very meger.
I have added the whole folder as Llibrary in netbeans project and whe i try to run the file i get the followig wrroes.
Exception in thread "main" java.lang.UnsatisfiedLinkError: FaceDetection.JNIOpenCV.detectFace(IILjava/lang/String;Ljava/lang/String;)[I
at FaceDetection.JNIOpenCV.detectFace(Native Method)
at FaceDetection.FaceDetection.<init>(FaceDetection.java:19)
at FaceDetection.FaceDetection.main(FaceDetection.java:29)
