i'm completed a program, and have class files compiled

how do i get them to run on other computers (pc's for now, running windows, to keep it simple) i send the class files to the other computer, but how do i run it??

if i put 'java myprog.class' it doesn't do anything (under xp)..and i don't really wanna buy software that'll create an exe, but i'm sure you can run the class files on other computer that don't have the whole java library..how do i do it??

thanx
