📇 Contact Manager App
The Contact Manager App is a Java-based web application designed to store and manage contact information efficiently. It uses JSP, Servlets, and JDBC to interact with a MySQL database, providing a simple user interface to perform basic CRUD operations like adding and deleting contacts. This project is ideal for beginners learning Java Web Development and database connectivity.
✨ Key Features
✔ Add new contacts with details like Name, Email & Phone Number ✔ View a list of all saved contacts in a structured format ✔ Delete any contact from the database instantly ✔ Real-time database connection using JDBC ✔ Clean and modular code with MVC pattern ✔ Built using standard Java web technologies common in real projects
🧰 Tech Stack & Tools Used Technology Purpose Java (JDK 24+) Application logic JSP (Java Server Pages) UI and view rendering Servlets Controllers and request handling JDBC Database connectivity MySQL Data storage Apache Tomcat Web server (e.g. Port 8081) Maven Dependency and build management IntelliJ IDEA / Eclipse Recommended IDE 📌 Database Design
Database Name: contactdb Table Name: contacts
Table Schema CREATE TABLE contacts ( id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(100) NOT NULL, email VARCHAR(100) UNIQUE, phone VARCHAR(15) );
