How are the request flow and URL format implemented?
All requests are initially handled by a controller servlet (one per module, several per application), and the URL of this servlet is chosen by the developer. This servlet dispatches a request to a request-specific controller object (the ViewBean), which then ultimately forwards the request to another resource (a JSP, ViewBean, or other Web resource). The source code for the servlet and its dispatching mechanism is fully under developer control, and developers are encouraged to learn the details of this mechanism by reading the well-commented source.
