Oh is this about a link, I don't have a link sorry, instead I will copy and
paste the whole code , not in fragments. sorry about that. Well there are many
classes, send me an email, I can send a jar file fo my entire classes. Let me
know what problem I am having. I get an error with waypoint from this class.
