+ The Struts Core Controller acts as a bridge between the application's
+ Model and the web View. When a request is received, the Controller
invokes
+ the Struts <strong>Action</strong> class. The Action consults with the
Model
+ (or, preferably, a <strong>Facade</strong> representing your Model)
+ to examine or update the application's state.
+ Struts Core provides an <strong>ActionForm</strong> class to help
transfer
+ data between Model and View.

+ Most often, the Model is represented as a set of
<strong>JavaBeans</strong>.
+ Typically, developers will use the Commons <strong>BeanUtils</strong>
to
+ transfer data between ActionForms and the Model objects (or a Facade).
+ Preferably, the Model will do the "heavy lifting",
+ and the Action will act as a "traffic cop" or adapter.
