JEE Demos

This repository includes JEE demos for Servlets, JSPs, JSFs, JAX-RS and EJBs.

Recommendations and Dev Choices

  • IDE: Opensource Eclipse IDE for JEE is recommended
  • JDK: Open JDK 1.8 (not JRE) to use JavaEE/JakartaEE 8 recommended
  • JEE Server: Glassfish v5.1 supporting JavaEE/JakartaEE 8 recommended

Setting Up Development Environment

  1. Make sure you downloaded Eclipse IDE for JEE Development from here
  2. Please refer here to setup Eclipse IDE
  3. Please refer here to setup a new GlassFish Server instance in Eclipse IDE
  4. Download and install OpenJDK 1.8 (if not available) from here

Building the Source Code

Each demo1,...demo5 folders are considered separate JEE projects for the IDE.

Running Gradle Tasks through Terminal

You can simply navigate into the demoN folder and execute the following;

For Linux / MacOSX;

cd demo1
./gradlew clean build

For Windows;

cd demo1
./gradlew.bat clean build
