🌐📚 Distributed JEE Application with EJB and JPA

This project demonstrates the implementation of a distributed Java EE application using EJB3, JPA, and MySQL. The goal is to create a modular and scalable system that manages student data with full CRUD operations.

---

🎯 Objective

To practice and implement a distributed JEE application by leveraging EJB3, JPA, and WildFly. The application performs CRUD operations on student data stored in a MySQL database.

---

🚀 Features

• Distributed Architecture: EJB Session Beans for modular and reusable components.
• CRUD Operations: Full management of student data (create, read, update, delete).
• Database Integration: Persistent storage with JPA and MySQL.
• Dynamic Web Application: Servlet-based frontend consuming remote EJB methods.
• Standards-Compliant: Built with Jakarta EE standards, ensuring portability and scalability.

⚙️ Setup & Installation

Prerequisites :

• Java 11+ installed.
• Maven for project management.
• MySQL with a database named Getudiants.

Steps to Run

• Clone the Repository:

git clone https://github.com/YourUsername/Distributed-JEE-Application.git
cd Distributed-JEE-Application
Set Up the Database:

• Create a MySQL database:

CREATE DATABASE Getudiants; Update persistence.xml with your MySQL credentials:

<property name="hibernate.connection.username" value="your-username" />
<property name="hibernate.connection.password" value="your-password" />
Deploy the EJB Module:

Package the EJB project using Maven:

mvn clean package

• Deploy the EJB JAR to your WildFly server:

Deploy the Web Module Package the web project using Maven:

mvn clean package

• Deploy the WAR file to WildFly: Access the Application:

Open your browser and navigate to the web application:
