In the model/view/controller paradigm, ServletManager can be used as an XML-based servlet controller package. Supports extensive tracing, logging, and debugging facilities in the starter set of listeners. This allows a Web application programmer to declare the entire application's flow, application state rules, exception handling, authorization rules, view code (JavaTM server pages (JSPs)) per state in an XML-based state table and model code (business logic) per state. |
