hi ....need to know about server side validation

HI all

we have been working on a project using jsp & ejb's & Jboss as a server .

on the client side we have applied java Script for client side validation, but have to apply server side validation, so that no proxy server can inject data .

we actually wanna check data befor inserting it in the data base, like its lenght, format etc.

can it be done using EJB's ?

or if there is any other technique for applying server side validation

any links or documentation or examples would b appriciated

With thanks in advance
