This program has been built on MSVC 6 many times.  Please try it again 
after upgrading to service pack 5.

> 	The second issue: After the compilation succeed, I move the jar (InsightToolkit.jar) and the corresponding Dll’s from the build path to another directory. When I run my first program, the java runtime was unable to load the native libraries, no mater I correctly set my CLASSPATH and my PATH (currently I use windows) environment variables to the directory where I move the files.

I think that hard coding the path of the Dlls in this class removes flexibility to the applications developed with the ITK java Wrappers.

This also lets it work from the build tree out of the box without 
setting anything but the classpath to point at the jar.  What it should 
probably do is look in the directory containing the jar first, and then 
in the hardcoded path.  Please add this as a feature request to the bug 
tracker at
