I was wondering if anyone could suggest a good strategy for maintaining user entered data across, say, validation errors.
My goal is that when a user submits a form to a servlet and something goes wrong, I would like to redisplay the page that the user submitted the form from. I can accomplish this through response.sendRedirect(), but the user's data is gone. It appears that I have a new request object when I use sendRedirect().
Is there a good way to maintain the user's submitted data across multiple invocations of the same JSP?
