I have a Jsp which takes some form inputs from the user and sends it to a servlet. The servlet routes it to the appropriate CRUD operation depending on the button user selected. there is DAO class to create conection to the datasource. now where should the validations for the form inputs be done. 'client side' or 'server side'? and what does these terms mean.
is it true that if validations are done client side then there are chances of the browser ignoring them.
