Best Practices for AppFuse Web Core Classes

Hi,

I hope some can answer my question.

I'm using the modular version of AppFuse 2.0.2 + Struts 2 + JPA.

There is a tutorial about how to export "AppFuse Core Classes" at
http://www.appfuse.org/display/APF/AppFuse+Core+Classes, but thats only for model beans.

I'm going to change some code in the SignupAction and other actions too. What should I do ?

1. Create a SignupAction.java inside my own package (my domain) and extend the AppFuse SignupAction
  or ?

2. Export Appfuse Web Classes like when you do for AppFuse Core Classes ?

3. Other ?

Is there any guide for that or could some give a best way to do.
