Struts framework helps to develop web applications that utilize an MVC architecture. It helps separate the display logic from business logic.
Model = business logic (data model)
View = presentation
Controller = navigational code between model and view
The Flow
Lets see the important properties of Action Mappings.
Action mappings represent the information that the controller knows about the mapping of a particular request to an instance of a particular Action class. The request processor selects an appropriate action for each request based on the action mappings ( action-mapping elements) defined in the Struts configuration file.

The Flow
On receiving a HTTP request from the action servlet, the request
processor, another key controller component, performs core request processing as
follows:
- Uses the module's Struts configuration file to determine the configured action mapping for the request.
- Uses the module's Struts configuration file to locate or instantiate an appropriate action form for the request, if necessary, and populates and validates it.
- Uses the module's Struts configuration file to locate or instantiate an appropriate action for the request.
- Passes the request, action form, and action mapping to the action (step 3 in the preceding diagram).
- Forwards the user to the appropriate view element when the action is completed
