  Hello,
all i can say is it should work  :)

NativeWindowFactory is in nativewindow.all.jar. If the jar is in the
classpath it should also be found at runtime.

we recently got notified about corrupted jar files on the webserver jogamp.org.
Maybe its safer to download the files directly from the build server for
a while:

btw your english is good, no reason to be sorry :)
