Is there any limit with session management in your application server? I mean, Websphere, for example, warns you about storing more than 16K in session.
To bypass this problem, there is a good alternative (to the best of my knowledge): create a Map where keys would be session IDs and values would be data (this would lead to the need of creating a wrapper for all your data). Then, this Map could be placed in application context, servlet context (in case of Struts which only uses one ActionServlet) or even as a static Map shared by all users in the application server (of course, with no clustering at all).
I would be delighted to hear some comments and suggestions in this solution.

You can set the scope attribute of your action mappings to session, then you don't have to do the code you have below. The form instance that is passed into execute() will either be what was in session, or a newly created one.
I'm not sure about the answer to the second part of your question, but I'm about 99.99% sure you can still use it (anyone else verify?)

Great ...... thanks for all the responses...
I think I will go with the ActionForm stored in session-scope.
Just wanting to confirm, that I will need to perform the following code changes:
================== public ActionForward execute( ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse ) throws Exception { actionForm = httpServletRequest.getSession().getAttribute("myForm"); // ... // normal code follows!!! } ==================
Also, would I be correct in saying that I will be unable to use the ValidatorActionForm.
TIA,
Kunal

This is more or less what a session-scope ActionForm is for. As long as the
ActionForm class contains all the properties and methods for all the screen
it will service, just putting it in session I think is your best bet. As
someone else said, hidden form fields are your other choice. Actually, you
could also store the data temporarily to a database, but if you would even
consider that, session is really the right answer.
