I'm just starting with Java and my first duty is to do the validation for
the application.
The group I'm working with wants to have a server side validation and not
client side validation with Java Script.
Well I'm a back end programmer in VB, and C++, in my experience a safe and
reliable application must have both client and server validation.
Can someone clarify to me why my group believes that just server validation
is enough, or I'm wrong and a 100% java application does not need client
validation.

Thanks
