Login System Using Servlets and JSP Overview The Login System Using Servlets and JSP is a simple, yet powerful web application designed to provide secure and efficient login functionality. Built using Java Servlets and JavaServer Pages (JSP), this project showcases the integration of server-side Java technologies to manage user authentication and session management. It offers users the ability to securely log in with their credentials and view a personalized welcome page.

This project is a great starting point for developers learning Java web technologies and understanding how to implement a basic login system using Servlets and JSP.

Features User Authentication: Secure login with username and password verification. Session Management: Uses HTTP sessions to maintain user state after login. Simple and Intuitive UI: A basic login form with error handling and validation. Error Messages: Displays clear error messages for invalid login attempts. Logout Functionality: Allows users to log out and end the session securely. Servlet and JSP Integration: Demonstrates the interaction between Servlets and JSPs for handling requests and presenting views. Technologies Used Java: The core language for building the backend of the application. Servlets: Server-side Java components that handle HTTP requests and responses. JSP (JavaServer Pages): Used for dynamic web page creation and displaying views. Session Management: HTTP sessions for user authentication. Tomcat: Web server for hosting the application. Setup Instructions Follow these steps to set up the Login System Using Servlets and JSP:

Clone or Download the Repository: Clone the repository or download the ZIP file to your local machine.

Prerequisites:

Java Development Kit (JDK) 8 or higher. Apache Tomcat (or any servlet container) for running the application. Import the Project into an IDE: Import the project into your preferred Java IDE (e.g., Eclipse, IntelliJ IDEA).

Configure the Tomcat Server:

If using Eclipse or IntelliJ, configure Apache Tomcat in your IDE. Make sure the server is running on the correct port (usually 8080). Deploy the Application:

In your IDE, deploy the project to Tomcat by running it as a web application. Access the Application:

Open your browser and go to http://localhost:8080/LoginSystem to access the login page. How to Use Login Page:

Navigate to the Login Page where you’ll be prompted to enter your username and password. Enter the credentials, and click the Login button. User Authentication:

The application will validate the login credentials. If the credentials are correct, you will be redirected to a Welcome Page with a personalized message. Logout:

Once logged in, you can click the Logout button to securely end your session. Error Handling:

If the username or password is incorrect, an error message will be displayed. You can try again with the correct credentials. Example Screenshots Login Page – A clean login form. Welcome Page – A personalized page after successful login. Error Message – Error displayed when invalid login credentials are provided.
