If your goal is to retain a value from the time you prepare it in an
action, through to the JSP that's displayed, and all the way through
till the user submits the form on the JSP, simply using redirect=false
wouldn't be enough. You'd want to either place the value in a hidden
field to be submitted with the rest of the form, or put the value in
session scope.

When you hit submit, that generates a *new* request, and therefore
anything you placed in the scope of the *previous* request is no
longer accessible.
