My $0.02: I did something similar with a PHP thing I've been working
on, which should work basically the same with servlets. I set a
session variable to be an "error flag", and then forwarded to the page
that has the form the user submitted. From there I checked the error
flag, and if true, display the error message. This is pretty much the
same as what Geeta suggested, only using session variables instead of
passing something along the query string. If you do it the session
way, be sure to unset the session variable immediately after use, as
you don't want the error message to show up every time the page loads.
