Unsatisfied Linker Error : library file not found

I am writing test cases for a class that calls the constructor of another class that has a static block that loads a c++ library,

static
  {
          System.loadLibrary("PixelProxy_jni");
  }

I have specified the library path as,

-Djava.libarary.path=C:\Users\Desktop\libPixelProxy_jni.so

in the vm arguments in eclipse, but still it doesn't work.

Please help me find a solution for this

stack trace

From that file path, it looks like you're on windows, which means that loadLibrary will not look for a file named libPixelProxy_jni.so, it will look for a file named PixelProxy_jni.dll. (You can find out exactly what it will look for by using System.mapLibraryName.)

You can either find a .dll of the library, compile one yourself, or try System.load, which allows you to load a native library from an absolute path:

System.load("C:\Users\Desktop\libPixelProxy_jni.so");

But that will only work if the library was actually compiled for windows.
