我构建了webservice，它具有方法面部识别功能。 Webservice reslful框架，tomcat服务器，人脸识别使用javacv。它有问题：
OpenCV错误：未指定错误（无法打开文件进行编写！）在cv :: FaceRecognizer :: load，file ........ \ opencv \ modules \ contrib \ src \ facerec.cpp中，第398行 19-Mar-2015 10：21：48.340 SEVERE [http-nio-8084-exec-13] com.service.Searcher.FaceRecognitionService.findInfomation null java.lang.RuntimeException：........ \ opencv \ modules \ contrib \ src \ facerec.cpp：398：错误：（ - 2）无法打开文件进行写入！在函数cv :: FaceRecognizer :: load

代码java：
int[] predictedLabel = {-1};
double[] confidence = {0.0};
FaceRecognizer model = null;
switch (param) {
case CV_FISHER:
model = createFisherFaceRecognizer();
model.load(CV_FISHER + ".model");
break;
case CV_EIGEN:
model = createEigenFaceRecognizer();
model.load(CV_EIGEN + ".model");
break;
case CV_LBPH:
model = createLBPHFaceRecognizer();
model.load(CV_LBPH + ".model");
break;
default:
break;
}
Mat testImage = imread(image, CV_LOAD_IMAGE_GRAYSCALE);
resize(testImage, testImage, new Size(92, 112));
model.predict(testImage, predictedLabel, confidence);
System.out.println(predictedLabel[0] + " " + confidence[0]);
return predictedLabel[0];
请帮我修理一下。 谢谢你
