Laurie:
I alyways use a redirect after a form post to avoid
the stupid page expired warning if the user hits the
reload button.
I think we will save the ActionSupport instance in the
session and get it back from there.
Thanks,
Neil

My first suggestion would be to get rid of the redirect to a separate
servlet and serve the CSV response directly from the action. Is there a
reason you can't do that?
There's no way your servlet can get the action class instance, since
action instances are request scoped; the instance no longer exists in
the new request the servlet receives.
Your options in this case (or any other case where you want to use data
from one request in a subsequent request) are pretty much limited to
either including the data in the redirect URL's query parameters, as you
are doing, storing them in the user's session, as you suggested, or
persisting them somewhere else, such as a database.
