On second thought there is a difference, The problem isn't just a sequence of instructions but having sufficient permission to execute. The Java JVM does not run as root. So,you need something that runs as root to change permissions to enable Java access.
IMO a script maybe the best solution since it is easily integrated into initrc. In fact, that is a large part of what that script does.
