Office Management Application

A fully custom-built office application developed in Java 17 and JavaFX 17, without any external frameworks, ensuring complete control over the architecture and implementation.

Overview
This application is designed as a multi-module office management system, featuring:
✅ Chat Panel – Real-time messaging using WebSocket communication.
✅ Task Management – Organize and assign tasks efficiently.
✅ Note Management – Create, store, and edit notes in a structured way.
✅ Cloud Drive – A file storage system with a dedicated file server.
✅ Admin Management Panel – Accessible only for ADMIN users, providing full control over users and groups.

The application follows a client-server architecture, with a modular structure, consisting of the following servers:
🔹 Gateway Server – Routes and proxies requests between the client and backend services.
🔹 Authentication Server – Manages user authentication and authorization.
🔹 Database Server – Handles structured data storage and retrieval.
🔹 File Server – Provides storage functionality for user files.
🔹 WebSocket Server – Enables real-time chat communication.

The client application is entirely built with JavaFX, without the use of any third-party UI frameworks, to ensure maximum flexibility and full customizability.

⚙️ Technical Setup & Requirements Database Server Configuration

1️⃣ Run all SQL scripts in the exact order they are listed in the project.
2️⃣ User Configuration – The database connection user is defined in Script #2. You can either keep the default user or change it, but this will require updating the credentials in: resources/config/db/connection.properties
3️⃣ First ADMIN User – Script #26 contains an INSERT statement for creating the first user with ADMIN role. This is required to log in and start managing users and groups.

File Server Configuration
📂 A configuration directory must be created in the project root, containing a file named config.txt. This file must define the path to user resources using the key "userResourcepath" for example: userResourcePath=D:/Drive/Users

🚀 First-Time Setup for Storage
After inserting the first ADMIN user into the database, follow these steps:
1️⃣ Retrieve the user's ID from the database.
2️⃣ Convert the ID to lowercase.
3️⃣ Manually create a directory at the specified userResourcePath, using the lowercase ID as the folder name.
4️⃣ Inside the user’s folder, create the following three directories:
Drive/
Notes/
Thumbnail/
This ensures that the Note Management and Cloud Drive modules work correctly.

🏗️ Server Startup Order

🔹 The order of starting individual servers is flexible, except for WebSocket.
🔹 The WebSocket Server must be started before the Gateway Server to properly establish the connection.
🔹 The Client Application should be launched last, after all backend services are running.

🛠️ Why This Project?

Unlike many JavaFX projects, this application was built entirely from scratch – no Spring, no Hibernate, no external UI libraries. This approach ensures:
✔ Deeper understanding of JavaFX and Java 17 features.
✔ Better control over architecture without relying on heavy frameworks.
✔ Lightweight and customizable application behavior.
