Answer 1

The .jar file must contain all your classes that are needed during runtime. That includes the GameWindow$2$10 classes, they are the anonymous inner classes that you wrote in your GameWindow class.

Other .jar files are not included in your .jar file, but you can reference them using the Class-path attribute in your manifest.
