I'm looking for a movie about a young man that tried to join military but was rejected for having flat feet

In a nutshell from what I can remember, a young white kid tries to join the army to fight in some war but gets rejected for having flat feet. A man that lives close to him is an asian man from what I can remember. The kid with his friends throws a bottle or something at the mans house and it catches on fire....anyway somehow the kid and the old man become friends...thats all I can remember about the movie....please help its driving me nucking futs!!!
