There is some work going on in the Jakarta Commons project to define a
nice reusable "cache" API for this sort of thing. It hasn't gotten as far
as real live code yet, but that shouldn't be too far away. I'd subscribe
to the "jakarta-commons" mailing list to keep track of what's going on
there.
As a general note, a bunch of the general purpose Struts utility
components (like BeanUtils and the Digester) are being migrated over to
Commons because they are generally useful - a future version of Struts
will use the Commons versions instead of the ones currently in
org.apache.struts.util.
