<btw> While on the topic of struts design patterns and exceptions (the ones you throw yourself) I would strongly recomend following the tip Ted posted earlier about using chained exceptions: http://husted.com/struts/tips/015.html They really are very useful! :-) </btw>

J2EE security can help with the first and struts declarative exception handling (as of 1.1) can help with the latter. You can use container managed security (in your case you would probably want to use 'form based' security). See the struts documentation for details on declarative exception handling (note that this could not be plugged into a login exception as the container would forward to a specified page in the event of an invalid login). Jon Ridgway -----Original Message----- From: ROSSEL Olivier [mailto:[EMAIL PROTECTED]] Sent: 18 November 2002 09:53 To: '[EMAIL PROTECTED]' Subject: Question about a Struts design pattern My application is made with tiles. As is: ----------------------- | T | L | ----------------------- | | | C | | | | | ----------------------- T: Title L: Login form C: Content The URL for this app is: /Main.jsp The login phase is made of 2 forms: the Username form and the Password form. The first one leads to the second one, and the second one leads to either: LoginSuccessfull or to NoSuchUser. My question is how to make those forms: to me, I will handle the L part of Main.jsp with a LoginDisplayer action. This action will check the state of the Login session object and either forward to Username.jsp, Password.jsp, LoginSuccessful or NoSuchUser. And each form (Username form and Password form) will be handled by the LoginManager action, which fills the Login object. And redirect to Main.jsp. I think this is the correct way to manage a kind of portlet in my app. My main problem is how to manage errors/exceptions. In the process above, the two actions (LoginDisplayer and LoginManager) are completely separated and the only central point is the Login session object. Should I pass excetions through that object? I am newbie with Struts, and wish to have a few design patterns for such an app. Any help is welcome. ---cut here--- This e-mail is intended only for the above addressee.
