Advanced Jakarta Servlets: Servlet Request Listeners

Servlet request listeners allow developers to monitor the lifecycle of individual requests, such as when a request is created or destroyed. They are useful for tracking request-level events, initializing resources, or logging request-specific data across the application.In this course, you will continue your study of listeners, this time in order to learn about HTTP session and servlet request listeners and how they help monitor the lifecycle of sessions and requests in a servlet-based web application. Explore the different types of listeners available and how they can be used to track user activity, and implement logging or analytics tied to request and session events. Discover how to build and implement a servlet request listener, set up a servlet that handles GET and POST requests, and use a servlet request attribute listener to monitor the lifecycle of request-scoped attributes. Throughout this process, the listener will log attribute events, helping you understand how data moves and changes during the request lifecycle.
