java.lang.UnsatisfiedLinkError: org.opencv.videoio.VideoCapture.VideoCapture_2(I)J

Hi

I am facing below issue while running a sample code, just accessing VideoCapture instance.
java.lang.UnsatisfiedLinkError: org.opencv.videoio.VideoCapture.VideoCapture_2(I)J

I am working on Ubuntu and have open CV 3.4 installed properly.
I already set all class paths in environment variables as below :

OPENCV_HOME="/home/.../softwares/opencv-3.2.0/"
OPENCV_LIB="/home/.../softwares/opencv-3.2.0/build/lib"
OPENCV_JAR="/home/.../softwares/opencv-3.2.0/build/bin/opencv-320.jar"

I followed all the step for adding library in eclipse, whether it is by adding user library or by adding jar files. I followed for JNI.

I tried a lot.

Let me know what is issue or what i am missing .

Thanks
Arun

Hi All,
I am facing the same issue with opencv_320.
While i am running the same code with eclipse it is working fine.
But while creating a fat jar of my project and running it from command line i am getting the below exception.

Exception in thread "Thread-1" java.lang.UnsatisfiedLinkError: org.opencv.videoio.VideoCapture.VideoCapture_3()J

at org.opencv.videoio.VideoCapture.(VideoCapture.java:68)
at com.iot.video.app.kafka.collector.VideoEventGenerator.generateEvent(VideoEventGenerator.java:97)

Note: I have placed the DLL file inside my windows/system 32 directory.
