We had some actions which would create beans from request and session
attributes and place the bean in the request. This made it hard to go
'back' to the page in question, because it was no longer just a matter of
getting the form attributes in the request and forwarding to the JSP, you
also had to create a bean to go along with it.
Most of these got fixed so that all relevant information for the JSP was in
the form bean attributes and hence could be passed in via a URL.
One of the points on the elements of struts development page that rang
especially true was having base actions. We also had a base form bean as
well.
Our structure is like this:
Form Bean -> Project Base Form Bean -> Multitask Base Form Bean
Action -> Project Base Action -> Multitask Base Action
where -> is "extends".
The project 'base's hold project relevant code, and the company (Multitask)
level holds stuff reusable across projects.
We had a value object layer to separate EJBs and actions as well, with
Session EJB methods only accepting value objects as parameters, not form
beans. The value objects had a 'base' class as well that handled copying
bean properties and had a generic toString as well.

Please do -- I think the world may be ready for "The Elements of Struts
Development"

The "avoid transient beans" point sounds especially interesting ...
