1) "input" attribute name is misleading. It is not actually an input
page, it is a location where control will be forwarded in case of
error, that is, if ActionForm.validate() returns non-null non-empty
object.
2) Do not navigate directly to JSP page in browser, navigate to
action. Action is supposed to be a controller that tackles with input
data, JSP page is a view that displays output data.
3) Because of (2), forward to JSP page from your action mapping only
when you want to display the page.
4) If you navigate directly to a JSP page, your action class will
never be called, even if the page is defined as "input" for some
action. In your particular case, you forward to
"/jsp/customer/CustomerConfirm.jsp". The action class will never be
called.
