I think the JServe process is keeping track of the classes it has
loaded by class name, and once it has loaded that name once, it
won't reload it.
Because all your students are using the same class name, the process
is loading the first student's version, and re-using it for all
subsequent accesses.
I think you need to either have the students use unique class names, or
find a way to force JServe to reload classes even if JServe thinks it
has seen them before. Bouncing JServe would do it but that probably
isn't an option for a lab server.
I see this sort of behaviour running unit tests with JUnit. JUnit works
around this problem by providing a custom class loader that does not
attempt to be so clever.
Hopefully someone with specific JServe experience can offer a definitive
solution for your problem.

No matter what we think of Linux versus FreeBSD, etc., the one thing I
really like about Linux is that it has Microsoft worried. Anything
that kicks a monopoly in the pants has got to be good for something.
