Re: [WebMacro-user] Validation [was How to subclass WebContext?]

[Nick S. <NSa...@ms...>]

Hi 

I've been using webMacro in projects for a couple of years now.
We use an opensource validation project called formproc.
www.formproc.org 

It's not terribly well documented but at least all the source code is
there. It works well with webmacro because
it's server side and not tied to any particular technology (except
Java). It allows reuse of validators and can certainly cut down on
validation code. It also features autopopulation of value objects and
type conversion.

It all depends upon how happy you are about maintaining a separate XML
configuration file for validations.

As for client side validation using javascript, I used it for quite a
long time but I've struggled so many times with quirky browser versions
that I try and avoid it altogether if I can.



Regards

Nick Sanderson

Just realize that doing client side validation does not absolve you
from having to do server side validation as well.  Clients can and do
send all kinds of wacky things.
