Loading DLL in Java - Eclipse - JNI

I am trying to load a dll in java using the following code System.loadLibrary("mydll");

The project is placed in D:\development\project\ and i have placed the dll on D:. I then gave following VM argument in eclipse configuration -Djava.library.path=D:/

But when i run i get UnsatisifiedLinkerError. After googling a bit, I used System.load("D:\mydll.dll");
