🚀 Java-EAR

This project is a modular Jakarta EE 10 enterprise application developed using Maven. It follows the standard multi-module EAR structure, including:

• core – Shared model classes.
• ejb – Stateless session beans exposing business logic via remote interfaces.
• web – Servlet-based front-end consuming EJBs.
• ear – EAR module that packages all components into a deployable archive.

📦 Project Structure

JIAT-EAR/
├── core/        # Contains entity classes (like Product)
├── ejb/         # EJB module with business logic
├── web/         # WAR module with servlets
└── ear/         # EAR packaging module

🧱 Modules Overview

core Module

• Provides serializable model classes shared across the application.
• Example class: Product.java

ejb Module

• Contains a stateless EJB ProductSessionBean implementing the ProductService remote interface.
• Performs operations like:
  • Get product by ID
  • Get all products
  • Add/update/delete product (currently empty implementations)

web Module

• Provides a servlet Home.java that connects to the ProductService EJB.
• Displays a simple HTML response using servlet API.

ear Module

• Packages the entire application using the maven-ear-plugin.
• Includes core.jar, ejb.jar, and web.war.

💻 Technologies Used

• Jakarta EE 10
• Maven
• GlassFish 7 / Payara / WildFly (Jakarta EE compatible servers)
• Java 11
• Servlets & EJB (Stateless Beans)

🚀 How to Deploy

1. Build all modules using:

   mvn clean install
   

2. Deploy the EAR file (ear/target/ee-ear.ear) to a Jakarta EE compatible application server like:

   • GlassFish 7.x
   • Payara 6.x
   • WildFly 28+

3. Access the application:

   http://localhost:8080/ee-app/home
   

🔧 Future Enhancements

• Connect EJB to a real database using JPA and persistence.xml.
• Implement full CRUD operations in ProductSessionBean.
• Improve the front-end using JSP/JSF or modern frontend frameworks.
• Add authentication and authorization using Jakarta Security.
