java - OpenCV CascadeClassifier error -

-

i'm trying face detection through webcam, got error, cascadeclassifier error.

after testing, found line of code generate error 

cascadeclassifier face_cascade = new cascadeclassifier();

the error got 

exception in thread "main" java.lang.unsatisfiedlinkerror: org.opencv.objdetect.cascadeclassifier.cascadeclassifier_0()j     @ org.opencv.objdetect.cascadeclassifier.cascadeclassifier_0(native method)     @ org.opencv.objdetect.cascadeclassifier.<init>(cascadeclassifier.java:38)     @ camcapture.main(camcapture.java:24)

is know how solve this?

finally found answer,

i should load library before use cascadeclassifier. put code 

system.loadlibrary(core.native_library_name);

before cascadeclassifier.
