Hi,

Same problem for me :
java.lang.UnsatisfiedLinkError: no j3dcore-ogl-chk in java.library.path

I juste apply the readme with a very little example of sh3dfile.
I test to rename SweetHome3DViewer\lib\windows\i386\java3d.jar to see if it was a problem in the jar or in the path.

The error is different, so it seems that the filepatch is good...

An external requirement file for java3D ?
