Good, that's what I had assumed was the case. The app I'm converting next
week was based on a home-grown framework, and at least in the first
iteration it's easiest to not even think about ActionForms. We have Value
Object classes that are akin to ActionForms, except that they are just

Exactly, that's true. If you just want a struts action performing your
request processing you do not need any form.
Your mapping will look something like.
And in your action class you can then do the same thing as earlier :

Hello Geeta,
I've solved the problem, still don't really understand the reason.
I've defined a global forward for the input of my reluctant form, and
now, in case of validation error, I am forwarded to the desired page,
not to the blank one.
Thanks for you help.

Actually, it's not at all the case.
To merge a couple of simultaneous threads here, my app has a link that
lets the user toggle between languages. It calls an action that cares
nothing about any form. It just looks at the current Locale and goes on
:-)
You only need an ActionForm in your action
You can use request.getParameter()/getParameterValues() inside an Action to
retrieve form values without using an ActionForm. However, without an
ActionForm, you won't be able to use the Struts and related tags
and form validation.

Suggestion:
Rather than using the GLOBALS.Locale_Key in the session, use the
action.setLocale() method. This way you won't have to be changing your

For example, to decide between, say English and Russian, you can do this
and never mess with the httpSession directly.

In your action class, you have the request and the response object which

If the form exists in session scope, then you need to
