Anyway, I would keep validation code out of the JSP page.
Let's imagine you are creating an invoice with the data the user entered.
You could then use the object constructor to do the validation (this would
be a very smart thing to do, as it would enforce validation throughout the
whole application and all other uses of the class, if any) and raise an
exception accordingly. You could then catch the exception and display an
adequate message.
Even if you use JavaScript to do some validation, keep in mind that it can
be turned off. Server validation is mandatory in ANY important form.
