Synchronization does only work per-JVM. (Consider that you're synchronizing
on an object: that same object cannot possibly appear in two different
JVMs.)
The only work-around is to do locking yourself, using some resource (like a
file, a database, a servlet, or an RMI server) which is accessible from all
server machines/processes.
