Paul, thank you very much for your answer... but let me ask you for a few more details: I understood that I need a separation between simple pages and the pages, that do some business logic and that I should do that through an additional property in the ActionMappings of the struts-config. But where would I receive this ActionMapping and where should I save it? Furthermore is there a way to save an ActionMapping in a page? How to do that?
I would be very thankful if you could give me some more information about your idea. It sounds very interesting but I don´t really know what to do yet.. Thanks a lot Thomas Am Donnerstag, 31.
