Okay. A question for another approach: is there a way to save an ActionMapping (ActionConfig) into a page, that I´m able to recall later on? The idea is the following regarding the login-problem: I´ve defined a base-action that does a check if roles are defined in the ActionMapping. If this is the case it checks for the authentification and authorization. If one of these checks fail I redirect to a loginPage referenced through a global forward. If I could save the original ActionConfig in this loginPage, I could redirect the user to the page he originally wanted to go, if the login succeeds. My first idea was to save a String into a hidden field, but that would not work with objects as ActionConfig. Is there a possibility to save objects into the pages as I can do it with sessions?
