Gary,
There's no way to use jsp to validate items that happen on the client side.
What you can do is add some javascript functions which do this sort of
checking to
your jsp. The javascript functions are run by the client browser and will
provide the automatic checking. Of course, as you may have noticed in
recent posts
of the past, you need to check this on the server anyway since a user could
have
a browser which doesn't understand javascript, or the user could have
disabled
javascript. You can, however, expect that the values submitted will always
pass
validation on the server if the scripts have been correctly written and
executed.
