I used login as a simple example. But I have another case that is not as simple.
I have a 5 page check-out procedure. I want to set it up so that each page will forward to the previous page if the previous page's input fields have not been filled out yet. So each page has to do a different check. In other words, page 1 is the order page. Page 2 is enter your name & address, page 3 is the visa card info. So if they go straight to page 3, I want it to see that the name/address is not entered and go to that page. That page sees that no items are order and forwards to that page. So each page has a unique test and forward to. Any good ideas for this situation? thanks - dave ----- Original Message ----- From: "Cezar Nasui" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Tuesday, August 26, 2003 6:56 PM Subject: RE: login test in a jsp page - any suggestions > Hi Dave, > You have more choices to do user authentication, depending on your > application's need, your experience and determination :) > > 1. you can put it in every jsp but just think at the maintenance.
