OK I stuck all the .dylib's and .jnilib to /Library/Java/Extensions

When I try to run Cone5.java I get this error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no 
vtkCommonJava in java.library.path
         at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)
         at java.lang.Runtime.loadLibrary0(Runtime.java:822)
         at java.lang.System.loadLibrary(System.java:992)
         at Cone5.<clinit>(Cone5.java:16)
