Unique computer identifier in Java?

Thread view:

Hi everyone,

I need to identify a computer uniquely in Java code.

Host names, user names, IP addresses or even MAC addresses won't work as
these might be changed or the computer may not even be networked.

I know that Intel processors (and probably others as well) have a serial ID,
but how can I have something similar AND portable in Java?

With best regards,
Christian

If you ship bytecode, what's to prevent someone from running it in a VM
tailored to give your app what it expects to see?

How would one get a MAC address from Java without JNI?
