preprocess suggestion on struts change

[Kiet Nguyen <KN...@coolcast.com>]

I think action classes should allow a method(preloadPerform) definition.
This method would be called prior to the form being load.  This way we can
initialize form values and do pre-process stuff.  Currently I have a link to
"doSomething.do" which execute a corresponding DoSomethingAction class; the
action will then redirect to actual page.  I populate the form and do some
business processing in the doSomethingAction class.  Is this how it is
intended to work.

The Action.perform() method is where you should be setting up the beans your
JSP will use. That seems to be what you are doing (although typically you
will forward, rather than redirect, to the JSP page).

What is it that you're looking for in a pre-process method? Do you mean
something that is called before the action (in which case Oleg's reply
describes a solution), or something that is called after the perform()
method but before the JSP execution?

There is already such method in ActionServlet -
 processPreprocess

It is called before ActionForm creation and filling. In ActionServlet
it is empty - you can override it without any problems.
