Final Release (Module 3)

This release marks the completion of the distributed Spotify-like architecture. It integrates full location transparency, asynchronous data streaming, and enterprise-grade security.

Key Features Included:

• Hybrid Architecture: Control plane handled via Java RMI, Data plane handled via multi-threaded TCP Sockets.
• End-to-End Encryption: RMI Registry, method invocations, and Callbacks are fully secured using SslRMIClientSocketFactory and SslRMIServerSocketFactory with custom KeyStores.
• RMI Callbacks: Bi-directional communication allowing the server to remotely trigger the client's OS Media Player.
• Thread-Safe Concurrency: Robust handling of multiple connected clients using custom ConcurrentMultiMap and ConcurrentHashMap structures.
• File Auditing: Implemented a persistent .txt logging system to track stream sessions, IPs, and byte transfers.
• Dynamic Preloading: The server automatically scans and loads physical .mp3 and .jpg files across dynamic OS paths on startup.

Note: Ensure a valid keystore.jks is generated in the root directory before running the compiled classes.
