Cocoon definitely implements the following patterns:
1. Front Controller
2. Application Controller
3. View Helper (Functional Approach)
4. Composite View (Transformer View Management Strategy)
5. Service to Worker (via actions and generators)

Cocoon does not provide any J2EE Business Tier patterns. It is primarily an
implementation of the View and Controller, leaving the Model (i.e. the
Business Tier patterns) up to you.

FYI, I was looking at the Keel framework the other day. It is also Avalon
based and provides more Business Tier frameworks. However, it does not
appear to support J2EE - although one could argue that it implements the
J2EE patterns.
