HttpSession Listener Demo: Counting Logged-in Users in Servlets | Servlets

Описание: Welcome to our practical demo of HttpSession Listener in Servlets, where we'll showcase how to count logged-in users in your Java Servlet applications.

*Overview:*
HttpSession Listener is a powerful interface in Servlets that enables developers to track HttpSession lifecycle events. In this demo, we'll demonstrate how to leverage HttpSession Listener to count the number of logged-in users in real-time.

*Demo Highlights:*
Setting up the Servlet project environment.
Implementing a custom HttpSession Listener class to track session creation and destruction.
Utilizing session attributes to determine user login status.
Incrementing and decrementing a user counter based on login and logout events.
Displaying the count of logged-in users on a web page.

*Practical Implementation:*
We'll walk you through a step-by-step demonstration of how to implement HttpSession Listener to count logged-in users:
1. Creating the HttpSession Listener class with appropriate methods.
2. Registering the listener in the web.xml deployment descriptor or using annotations.
3. Implementing logic to update the user count based on session events.
4. Displaying the user count dynamically on the web page using Servlets and JSP.

*Code Walkthrough:*
You'll witness a detailed explanation of the code implementation, covering key concepts and best practices for counting logged-in users using HttpSession Listener in Servlets.

*Conclusion:*
By the end of this demo, you'll have a clear understanding of how to effectively utilize HttpSession Listener to monitor user activity and count logged-in users in your Servlet-based web applications.
