RE: [Springframework-developer] Spring MVC and validation

[Paul S. <tk...@tk...>]

I'll definitely investigate Valang in depth.  Thanks.  Just the
existence of some documentation puts it ahead of the commons validator
integration support in Spring modules. :)  

Valang looks pretty powerful, although it's still missing some basic
functionality like email, credit card validation.  Perhaps that sort of
stuff probably belongs more in the ValidatorUtils since Valang seems to
be a general purpose tool.  Regular expressions were alluded to
(customizing date parser), but I didn't see them specifically listed.

At some point I hope a validation framework gets integrated into Spring
MVC.  

Thanks again.  I'll go into lurker mode now. :)
