Subject: Re: Form validation From: Vic C <[EMAIL PROTECTED]> === It is a good practice to make all getters and setters take strings as arguments and return strings. HTTP is string based. Even on Int or Dates or whatever. The tricky part is that internaly they are implemented using native data types like BigDecimal or SQLDateTime (and persisted in a Disconnected RowSet for example). You immplement convert Strings to real data types within the getter if it works or store the wrong answer for a bit. Was that confusing? getters and setters use only string, but inside the bean they are implemented using db native types. (OT: and you can even format in the getter (with commans/decimals), localize dates, etc.) And on a related topic: Of course if you turn on the client side validation, JavaScript will be automaticaly generated to create a pop up Window (you code nothing other than place the JavaScript tag) on a submit to validate a date, #, reg. expression, CreditCard checksum, etc.
