The following page has been changed by MichaelJouravlev: http://wiki.apache.org/struts/StrutsManualActionClasses ------------------------------------------------------------------------------ * Update the server-side objects that will be used to create the next page of the user interface. These objects would typically be request scope or session scope beans, depending on how long you need to keep these items. * Return an appropriate !ActionForward object that identifies the next web resource. + The flip side of Struts flexibility is greater complexity of a most common use case of a web application. - The flip side of Struts flexibility is greater complexity of a most common request/response cycle comparing to similar ASP.NET request/response cycle: - - inline:asp_render_submit.gif == Action As Event Dispatcher == @@ -114, +112 @@ * handles different commands and events corresponding to a web resource (submit phase), and * selects an appropriate view based on current state of web resource (render phase). - inline:web_resource.gif + Implementing both input and output phases as well as event handlers in one Action class brings the complexity of Struts web form management down to the level of ASP.NET. - - == Action As Stateful Web Resource Manager == - - A stateful web resource stores its data in a session scope, usually in a session-scoped form bean associated with Action. This allows to use redirection without losing the data. Redirection can be used to render a view: submit action redirects to setup action instead of forwarding to it. - - If you can live with session-scoped data, your web application will sport much cleaner and user-friendly interface: - - * A web resource will have only one URL, the setup URL. Submit URL will be cleared by browser right after redirection. - * Navigating back and forward, as well as reloading a view is safe and does not cause resubmit. - * Several unsuccessful submit attempts to not accumulate in browser page history. - - inline:stateful_web_resource.gif + inline:web_resource_asp.gif == Action As Web Component Manager ==
