☕ Java EE Microservices Archive

A historical collection of Java EE/Jakarta EE microservice experiments, REST APIs, Payara Micro deployments, Docker configurations, and JWT authentication prototypes.

---

📚 About This Repository

This repository is a historical archive of multiple independent Java EE 8 application projects.

The projects were created to explore enterprise Java development, RESTful services, client-service communication, Docker-based deployments, Maven builds, and Payara application server environments.

Each project is maintained as a separate application within this repository.

⚠️ Historical Archive: These projects are no longer actively maintained and are preserved for reference, learning, and historical purposes.

🏗️ Project Architecture

The repository contains multiple independent applications that follow a client-service or REST API architecture.

A typical application flow looks like:

┌─────────────────────┐
│   Client Application │
└──────────┬──────────┘
           │
           ▼
      REST API
           │
           ▼
┌─────────────────────┐
│   Microservice       │
│   Java EE Application │
└──────────┬──────────┘
           │
           ▼
      Payara Micro
           │
           ▼
         Docker

The architecture varies between projects. This diagram represents the general development approach explored across the repository.

🚀 Project Commands

Individual projects include scripts for common development and deployment workflows.

Run

Starts the Docker environment and mounts the application deployment directory.

./run

Build

Builds the application and Docker image.

./build

Build and Run

Builds the application and Docker image, then runs the application locally.

./build-run

Build and Deploy

Builds the application and deploys the Docker image to a configured Docker registry.

./build-deploy

View Logs

Displays application logs when running with build-run.

./logs

The exact commands and Docker configuration may vary between individual projects.

---

🔗 Example REST Endpoints

The individual applications expose REST endpoints using paths similar to:

http://localhost:8080/{application-name}/rest/example

Example:

http://localhost:8080/EmployeeMicro/rest/example

---

🐳 Docker & Payara

The projects use Docker-based development environments with Payara for running Java EE applications.

The repository includes historical Docker and Payara configuration used during the development of these applications.

Some projects may use different runtime configurations depending on their original setup.

---

🔐 JWT Authentication Experiments

Some projects in this archive include historical experiments with JWT-based authentication and role-based access control.

Example roles included:

Admin
Supervisor

⚠️ Any keys, tokens, or authentication configuration included in the original historical codebase should be considered obsolete and must not be reused.

📚 Purpose of This Archive

This repository represents an earlier stage of my software development journey and preserves experiments with:

• Backend application development
• Java EE REST APIs
• Microservice architecture
• Client-service communication
• Docker-based deployments
• Maven project builds
• Payara Micro runtime
• JWT authentication concepts

The repository is maintained as a historical record rather than an actively developed project.
