Question

实际上我在使用opencv 3.0.0时检测到第一帧相机在Eclipse中崩溃。代码看起来像这样

public class main
{
static {
    System.out.println("java.library.path="+System.getProperty("java.library.path"));

    System.load(new File("/Desktop/opencv-3.0.0/build22/lib/libopencv_java300.dylib").getAbsolutePath());
//  System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    System.load(new File("/Documents/Mourish/java-proj/FaceDetector/libFaceDetector.so").getAbsolutePath());
System.out.println("Library loaded");

}

public static void main(String argv[]) {
    int n = 0 ;
    final Scalar    FACE_RECT_COLOR     = new Scalar(0, 255, 0, 255);

    MatOfRect faces = new MatOfRect();
//  CascadeClassifier cascadename = new CascadeClassifier("/Documents/FD/sample/lbpcascade_frontalface.xml");

     String s = "/Documents/FD/sample/lbpcascade_frontalface.xml";

     Imshow im = new Imshow("window");
    VideoCapture camera = new VideoCapture(0);

    if(!camera.isOpened()){
        System.out.println("Error");
    }
    else {
        Mat frame = new Mat();
        Mat out = new Mat();
        while(true){
            if (camera.read(frame)){

//              
                n = FaceDetector.sample(frame, out, faces, s);
                System.out.println("Frame Obtained");
                System.out.println("Captured Frame Width " + 
                frame.width() + " Height " + frame.height());


                Rect[] facesArray = faces.toArray();
                for (int i = 0; i < facesArray.length; i++)
                  Imgproc.rectangle(frame, facesArray[i].tl(), facesArray[i].br(), FACE_RECT_COLOR, 3);
                im.showImage(frame);
                Imgcodecs.imwrite("/Documents/FD/sample/camera.jpg", frame);

                System.out.println("OK");

                break;
            }
        }   
    }
//  return n;
}
}

在im.showImage（）中显示一些异常。我导入外部罐子opencv_300.jar。例外看起来像..，

Exception in thread "main" java.lang.NoClassDefFoundError: org/opencv/highgui/Highgui

Pls help me to find actual issue....
