Installing opencv(C:\OpenCV2.2) in the default location partially solves the 
problem. I think hardcodings in opencv_core.java should do the trick in future. 
Anyway after doing this you get:

Exception in thread "main" java.lang.UnsatisfiedLinkError:

OpenCV 2.2 does not come with binaries for 64-bit Windows. You need to compile 
them yourself

• Changed state: Invalid

In case anyone is encountering this issue as well,
a simple fix is to use the 32bit JDK instead of the 64bit JDK, this solves the 
linking error.

[GoogleCodeExporter]

I am using 32bit JDK and me too getting above exception 
Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Documents and 
Settings\Comp\Local Settings\Temp\jniopencv_core6193263930032021817.dll: %1 is 
not a valid Win32 application.

What is missing please help.
