Hi,
If you want to do it on the client-side, you will need JavaScript to check
what the user typed, and then "alert" some message to tell him that his
entries are wrong.
On the server-side, you can use the request.getParameter("myParam") to check
what the user typed, then send the appropriate response to the client.
Hope it helps.

Objet : Another question - validating user input in fields
Hi,
I have another question for you guys. Say, a user types an input into
the form, but with my checkings, I made that kind of input, say "$%#RG",
invalid. But I would like to write a line at the side of the form saying
"input must be from A-Z or a-z". I think in asp, its called text validators
or something. How do you do that in JSP?
From,
Anson
