Paul,
It is not clear what you are trying to do with your cache. But if cache
consistency across JVMs is important, then I can think of at least two
simple options:
Use a global session object -- this would work well for relatively small
caches.
Use RMI and run a long-lived service that acts as a global cache for all
CPs. (This can be very easy or very complex depending on what your cache
needs to do -- RMI itself is almost a no-brainer).
