How about storing a flag in the session for the servlet that will be gaining
the focus. Inside of either to doGet or DoPost method, have it check
(initially) the status of the flag in the session and if the flag is set,
revert to some error page. Then, in the page BEFORE the one which has the
submit button on it, reset the session flag. That way, the servlet will
know if the user has clicked the button more than once since the session can
only get set the flag the first time. This is the way we trap for the
multiple-submit button problem. You could also handle this at the
application level, but it'd be more wacky (ie: you could have a static
variable that contained a handle to the user and the page you wanted to trap
on and then have the servlet look at the flag in the app before doing
anything. This would trap for multiple browsers hitting the same page as
well).
