Why you should validate input January 17, 2008

If there was ever a lesson as to why you should always validate input, this is it.

The reason I am re-posting this (I think it’s been doing the rounds on the internet) is because I think every software developer should read it and take it to heart – the more people know about it, the less chance there is of this happening again.

Oh, and a (belated) happy new year to you all!

In Struts validation, if (for example) you want a field to be checked against a regex, and it must be specified, you need to use “required” as well as “mask”:

<field property="fieldName" depends="required,mask">

If you just use “mask” – like I did – the field won’t be required.

Yes, I know that was a stupid mistake, OK?
