They define the "service to worker" and "dispatcher view". On the first, you:
- call the controller
- call business tier
- display view
On dispatcher view, you simply "display the view", and they say that the needed data must already be on session scope or something like that. So this could be only used for static pages or "back buttons".
I agree, this is no
pattern. Some
j2ee patterns are really stupid. As I already said, I'm hating this book. Some patterns are useless, and the good patters are badly explained.
