Hi,

Action class overrides the excecute() method.Acts as a bridge between user invoked URI and a business method(command pattern).Its a part of Controller, not the model.

Please, to all who are answering MVC, it is not a "Design Pattern",it is framework, the Command Pattern is defined as,

                  Encapsulate a request as an object, thereby letting you parameterize clients with different requests, queue or log requests, and support undoable operations.

looks more closer to Action in struts

Struts framework is implementation of MVC architecture.The way action classes are getting accessed is an example of application controller.In this pattern pre and post processing of request gives you the appropriate results.

 

Remember Action class is an adapter between the contents of an incoming HTTP request and the corresponding business logic that should be executed to process this request. The controller will select an appropriate Action for each request, create an instance (if necessary), and call the execute method.

All Action classes are organised or defined within a MODEL layer
because this action classes contain buisness logic in form of
bean  those are invoked through Action Servlet(controller) to process
the reqest and create the response which in turn send back to view
layer (This is a MVC Pattern II )

Aditya, Exactly you are correct.

ActionServlet uses Command design pattern by calling the action classes

process() method of RequestProcessor uses template method desigb pattern by calling sequence of methods.

Action classes are used to transfer the HTTP Request to Model ( EJB,Plain java objects) and it uses Adaptor Design pattern.

Thank u all

Struts controller uses the command design pattern and the action classes use
the adapter design pattern. The process() method of the RequestProcessor uses
the template method design pattern. Struts also implement the following J2EE
design patterns.


Service to Worker
Dispatcher View
Composite View (Struts Tiles)
Front Controller
View Helper


Synchronizer Token , few coders say that struts 1 doesn't implements command
pattern properly.
