Here is what I do.
User (Generic Value Object)
UserBean (Extends form bean)
On initial page we have a link to viewUser.do?userId=100
In the Action class correspoding to viewUser.do, in the perform
That's what I do to.
Putting initialisation logic (like setting defaults) in the
form makes it a

accessible to the JSP. The second part there
I don't use validate(). The only validation I have is in the business logic.
The business class that does validation accepts returns a string version of
the data (as well as the proper data type).
validate() introduces a new element of execution flow into the design
(validation occurs in 2 diff.
If validation fails, the controller forwards to the input property,
which can be an action that populates any static properties on the
action form bean.

The best approach is to never let the user go directly to a JSP page.
Always pass control through an Action first, which gives you the

To prime the pump, you can have the index.jsp forward to an Action.
After that it should

just that above?I think I'll need to be doing the same thing.
