我在java web应用程序中使用opencv进行面部检测。因此，带有imagename的图像路径将传递给名为FaceDetection.java的java类的函数。 现在，当我运行它时，给出一个例外：
java.lang.UnsatisfiedLinkError: Native Library C:\Users\admin\.netbeans\7.0\apache-tomcat-7.0.14.0_base\work\Catalina\localhost\SharedCrpto1\loader\com\googlecode\javacv\cpp\windows-x86\jniopencv_objdetect.dll already loaded in another classloader
它可能是什么原因？如何克服它。请帮助
完成StackTrace如下：
java.lang.UnsatisfiedLinkError: Native Library C:\Users\admin\.netbeans\7.0\apache-tomcat-7.0.14.0_base\work\Catalina\localhost\SharedCrpto1\loader\com\googlecode\javacv\cpp\windows-x86\jniopencv_objdetect.dll already loaded in another classloader
