java is a programming language, not a operating system. hence you do not emulate java.
one would have to create an application which processes java code.
if noone here programs in java, you likely wont see any work ever with your idea. you better get crackin over there if you want it.
You need the ability to create a java virtual machine that can process java bytecode. This is actually a lot closer to an (virtual) operating system and/or emulator than anything else. The best way on xbox is via xbox-linux.
