There is already a topic on Spring Vs. Struts that touches on validation, but my question is a bit more specific.
Yes, I think Matt Riable uses Commons Validator with Spring MVC for Equinox/Appfuse, I am yet to have a good look at the code though.
What I want to know is how easy it would be to set it up with Spring MVC, compared to say Struts. And whether Spring MVC has support for doing basic validation on the server using the same rules (as specified for generating client side validatino code).
Most of the people who say that they have used Spring seem to use it with another MVC framework, which makes me wonder what limitations Spring MVC has compared to the other popular products.
