You might want to take a look at the "jelly" project (in commons-sandbox)
for a way to deal with this kind of thing. It's on my list of
technologies to evaluate for adding workflow support (post-Struts 1.1),
and it's much better (as well as farther along) than my original sandbox
project in that direction.
The basic thinking is that you'd script your Actions using Jelly, which
(among other things) can be made to call your business class methods
directly -- essentially you are just scripting an adapter between the web
tier and the business tier. This doesn't make encoding business logic
impossible, but it's enough wordier that constructive laziness will
encourage the correct behavior :-).
