As with the original design of Struts, I tried not to impose these
decisions on the application developer -- you can choose your favorite
techniques.  However, it's instructive to note that, for its own
purposes, this particular example app uses the IoC-ish configuration
support that JSF already provides (via managed beans) to wire together
the business logic and DAO instances.

If the logic were any more complicated than the current example (and
other use cases certainly will be), using a chain to assemble your
tier-crossing (or even the processing within a tier) seems to make a
lot of sense.
