hi Jeyakumar,
According to my understanding you need to perform a validation
on the data before performing your business logic.
your client would have avoided uing JS coz critical process like data in database operation would have to be performed by server side validation since you cant expect all your end users to enable javascript in their browser.
i use
struts serverside validation using validate method in ActionForm class(i suppose you are familiar with struts)
