I know there exist the read-mostly pattern for most of j2ee
implementations. However, I'm wondering how to invalidate *all* the
instances of a entity bean? I would like to know how the invalidateAll()
is implemented on weblogic? Should it be a search for all the read-only
entity beans instances and run a method that would throw a exception?
Should it be like that? Isn't expensive or is the only way to do it?

thanks,

Pedro Salazar.
