Problem: The newest Java versions don't use the directory user/lib in the library search path anymore.
Solution: Use our WIBU-KEY driver version 3.31 or higher (WibuKey.dmg). These versions contain the appropriate installation paths.
You also can copy the file libwibuKJni.jnilib into the system directory
[/System/Library/Frameworks/JavaVM.framework/Versions/1.4.1/Libraries] or into the directory
[/Library/Java/Extensions] in order to use a system directory valid for all Java versions.
