UnsatisfiedLinkError: no opencv_java249 in java.library.path


Exception is occurring from below line of code:

System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

Your program is trying to load a native library by the name of argument in call to loadLibrary method, which it is not able to locate. Make sure that native library (opencv.dll) is placed at one of the locations present in java.library.path system property as JVM looks at these locations for loading any native library (which might not contain 'java/jre/bin').

You can print java.library.path in your program like below:

System.out.println(System.getProperty("java.library.path"));

I haven't worked with the other library, but linking

For example you may use other native shared library with MD5 sources linked in during build (as shared library) - but you not copied this shared library to target application libs folder. I am not sure that implementation of MD5 related functions included into
