Say I have a web site where people can upload their code in class form. How could I limit what can actually be done within that class?

Answer 1

Implement a SecurityManager¹ for the client code. I would also recommend testing how long the code runs, and ending it if over a limit (this is more aimed at catching programmer incompetence that leads to an infinite loop, rather than deliberately malicious actions).
