After having installed the Java version 1.4.1 for Mac OS X the file libwibuKJni.jnilib can not be found anymore
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.
