Dispatcher View - what is really true?

My two sources on design patterns are the Oracle Page (http://java.sun.com/blueprints/corej2eepatterns/Patterns/DispatcherView.html) and the Core J2EE Patterns book (http://www.corej2eepatterns.com/Patterns2ndEd/DispatcherView.htm).

Both of them don't say the same thing about the Dispatcher View -

e.g.

Oracle: Business logic should be encapsulated in components other than the view.
Core J2EE: Introduces potential for poor separation of the view from the model and control logic.

...can anyone provide a link to a good resource on this design pattern?

Many thanks in advance!!
