Hmm Strugling a bit with this one now.?? I have extended requestProcessor and tried to perform a requestDispatch and responseRedirect, however both fail as the error message informs me the reponse has already been submitted. I thought i may be able to use declarative exception handling with global exceptions in the stuts config to redirect the user to my login page (but no joy!). Anyone have any ideas? Also what method should i override in the RequestProcessor when handling my login?
