Distributed Systems Project #2

This project implements a multithreaded key-value store using RPC (Java RMI). The project includes the following components:

1. RemoteCommandHandler - RMI interface for remote commands.
2. RemoteCommandHandlerImpl - Implementation of the RMI interface.
3. RMIServer - RMI server implementation.
4. RMIClient - RMI client implementation.

Prerequisites

Ensure that you have the Java Development Kit (JDK) installed on your system. You can download it from here.

Compilation

To compile the Java files, open a terminal or command prompt and navigate to the directory containing the source files. Use the following commands to compile each file:

javac RemoteCommandHandler.java RemoteCommandHandlerImpl.java RMIServer.java RMIClient.java

Running the Server

To start the RMI server, use the following commands. Replace <port> with the port number you wish to use (e.g., 32000).

java RMIServer <port>

Running the Client

To start the RMI client, use the following commands. Replace <hostname> with the server's hostname or IP address (e.g., localhost), and <port> with the same port number used for the server.

java RMIClient <hostname> <port>

Example Usage

Here is an example of how to run the servers and clients using port 32000 and localhost as the hostname.

Starting the RMI Server

java RMIServer 32000

Running the RMI Client

java RMIClient localhost 32000

Note: Ensure that the server is running first and use separate terminals or consoles for each client/server.
