We would like to use extensive EJB cachine (Commit option A or D), but would like to be able to drop the caches at certain points. Basically, we wan to give our users a button that deletes all the cached data from the JBoss CMP cache, how do we do that?

I can find various timeout options, but I can't find a a way to just outright delete the caches at certain times, in response to outside input.
