The main() method is a static (class) method, while you've defined an
non-static (instance) native method. (I'm assuming that LoadMain() and
LaunchMain() are the same, and you made a typo.) Either create an
instance of your Test class to invoke the native method, or make the
native method static. I don't know of any code that implements static
native methods, so you may be exploring uncharted territory there. :-)
