One implementation has been to subclass the Action object with another object (named
something like OurGeneralAction). All of your other Action objects, such as
LogonAction, LogoffAction, DoSomethingAction then subclass OurGeneralAction.
Just prior to returning an ActionForward from your specific Actions (Logon, Logoff,
etc.) you call a doBreadCrumb(String actionFwdName, HttpSession session) method that
is contained in OurGeneralAction.
doBreadCrumb() looks in the session object for another class (perhaps called
BreadCrumbs) that push or pop the actionFwdName from a stack.
That stack can then be used from a JSP using logic:iterate and bean:write to display
the list of "bread crumbs".
There are a variety of details and complexities that are left out of this description,
such as how you determine whether to push to, or pop from the stack, the exact text to
display for each bread crumb, etc. However, the general idea is represented.
