Just make sure that in the JAR file you provided to the neural network you included a class file called Gwindow that is located in com\maddox\gwindow folder the complete path is com\maddox\gwindow\Gwindow.class

here is the inheritance system for the draw method that is located in Gwindow

GWindow
↑
GWindowClient
↑
GWindowDialogClient
↑
GUIAwards.DialogClient

if one of the class in the chain is missing the method can't be resolved
