Not able to Validate form using JSR-303 validation implementation in Spring MVC

[jas preet]

I not able to validate simple form using JSR-303 implementation. I am not getting any exception, i think the problem is the framework is not invoking the @Valid annotation in the controller. I have been searching a lot.
I need to validate my login form. I have added the required jars in the classpath. Could not figure out the prblem.

Below is my servlet-xml file.
