You won't be able to re-compose the request object as if it was just
submitted. The quickest, dirtiest way is to just stow the form params
in the session upfront and then use them from the session later.
Example:
c:if test=${not empty param.mySubmitBtn}
c:set var=mySessProp scope=session
Oooops. Minor point in code, but one that could trip someone up if they
copy paste my code:
pYour request for ${SessProp} follows:/p
should read:
pYour request for ${mySessProp} follows:/p

Are you saying that I can't build a request and execute it directly,
Yes. I'm saying the original request won't be available. One other
alternative I can think of is for the last page submit to add all the

form action=page1.jsp?frmParam1=valuefrmParam2=value

Nobody has a suggestion about this?

Sure. I suggest you rephrase what you're actually trying to accomplish,
because the original made utterly no sense to me :-)

Ok, I'll try:
My app is started with a .jsp. On it the user enters a location ID.
When they click the submit button, it sends the request to a servlet
(call it page 1) which brings up information from a database about that
location, and gives them the option to make changes to the
