28: * Our Controller framework is build on top of the Spring's mvc framework. We provide
29: * an extra layer of abstraction that is not bound to any particular technology
30: * (servlet, portlet, thick GUI, etc). In order to use our framework you really
31: * should have good understanding of spring's mvc architecture especially the
32: * SimpleFormController and AbstractCommandController. We assume you understand
33: * what a backing object is, and the flow for form submission, and validation.
34: * <p/>
35: * This interface provides the basic Controller functionality. The system
36: * binds request params into the requestModel, and calls handleRequest. The requestModel
37: * type is configured in the spring config using the commandClass property. By default
38: * the no argument constructor will be used to create this object. If you require more
39: * control over how this backing object is created implement CustomCommandController.
