We are currently porting the entity portions of our design
over to EJB's to achieve the same effect.

What about an RMI object that can be accessed from each servlet/JSP? This
way you have one cache which is available from multiple JVM's and contexts
and you can keep the pool to a single instance?  Not sure of the symantics
of the JSP page (may need to use a bean), but why not try it?  Does anyone
have any experience that would show that this would be a bad thing to do?
It seems to me that this is a really powerful technique which isn't used
nearly enough.  Thoughts?
