Introduction

Welcome to our Simple Chat Application developed using Java RMI. This project demonstrates a basic real-time chat system where users can interact through a centralized server. The application leverages Java RMI for efficient client-server communication, offering both public and private messaging functionalities.

Features

• Real-time Messaging: Chat with other users in real time.
• Public and Private Messages: Send messages to all users or privately to a specific user.
• User Nicknames: Choose a nickname upon connection.
• Simple User Interface: Easy-to-use interface for quick interaction.
• Join/Leave Chat: Connect or disconnect from the chat server at any time.

Architecture

The application follows a client-server architecture using Java RMI. Here's a brief overview:

• ChatServer: Manages messaging logic and client connections.
• ChatClient: Connects to the server and allows user interaction via a graphical interface.
• ChatUI: Provides the graphical user interface for users.
• ConnectedClient: Manages connected clients and facilitates private messaging.

Installation

Prerequisites

• Java Development Kit (JDK) 8 or higher
• Apache Ant (optional, for building the project)

Steps

1. Clone the repository

  git clone git@github.com:ElazzouziHassan/RMI-Final.git

  cd RMI-Final

2. Compile the project

javac -d bin src/**/*.java

3. Start the RMI registry

rmiregistry

4. Run the server

java -cp bin server.ChatServer

4. Run the client
