Answer / Satyendra Pratap Singh

The Struts2 architecture consists of four main components: Action, Interceptor, Result, and Preparation/Execution/Validation stages. The action component is responsible for handling user requests and executing business logic. Interceptors are used to modify the request-response lifecycle, such as for logging or security checks. Results define the output of an action, such as a JSP page or JSON response. Finally, Preparation, Execution, and Validation stages are phases that occur during action processing.
