Project Description

This project includes two main parts:

1. File Upload/Download System: A client-server application that allows clients to upload, download, rename, delete, and synchronize files with a server.
2. Computation Server: A client-server application that provides basic computation services like addition and sorting of integers.

Both parts leverage Java RMI (Remote Method Invocation) to facilitate communication between the client and the server.

Features

Part 1: File Upload/Download System

• Upload files from client to server.
• Download files from server to client.
• Rename files on the server.
• Delete files on the server.
• Synchronize files between client and server.

Part 2: Computation Server

• Add two integers.
• Sort a list of integers.

Requirements

• Latest JDK (Java Development Kit). Download here
• (Optional) Any IDE (Integrated Development Environment) for Java development.

Installation

Verify JDK Installation

1. Download and install the latest JDK.

2. Verify the installation by running the following command in Command Prompt:

   java --version

   The output should resemble:

   java 21.0.2 2024-01-16 LTS
   Java(TM) SE Runtime Environment (build 21.0.2+13-LTS-58)
   Java HotSpot(TM) 64-Bit Server VM (build 21.0.2+13-LTS-58, mixed mode, sharing)

3. Clone the repository:

   git clone https://github.com/meggitt/JavaRMI.git
   cd JavaRMI

(Optional) Configure IDE

1. Install an IDE such as Eclipse or IntelliJ IDEA.
2. Configure the IDE for Java development.

Running the Application

Execution Through CMD

Part 1: File Upload/Download System

1. Compile and Run Server

   • Navigate to the Server directory inside FileUpload.

   • Execute the following commands to compile and run the server:

     javac Product.java
     javac ProductImpl.java
     javac Server.java
     java Server

2. Compile and Run Client

   • Navigate to the Client directory inside FileUpload.

   • Execute the following commands to compile the client:

     javac Product.java
     javac Client.java

3. Client Operations

   • Open a new command prompt tab.

   • Navigate to the Client directory and execute the following commands:

     java Client UPLOAD example.txt     # Uploads example.txt to server_folder
     java Client DOWNLOAD example.txt   # Downloads example.txt to client_folder (downloaded_example.txt)
     java Client                        # Synchronizes files (needs further inputs)
     java Client RENAME example.txt exampleNew.txt   # Renames example.txt to exampleNew.txt on server

Part 2: Computation Server

1. Compile and Run Server

   • Navigate to the AddSort directory.

   • Execute the following commands to compile and run the server:

     javac ComputationServer.java
     javac ComputationServerImpl.java
     javac Server.java
     java Server

2. Compile and Run Client

   • Navigate to the AddSort directory.

   • Execute the following command to compile the client:

     javac Client.java

3. Client Operations

   • Open a new command prompt tab.

   • Navigate to the AddSort directory and execute the following commands:

     java Client ADD 4 5                # Adds integers 4 and 5
     java Client SORT 3 6 1 33 35       # Sorts integers 3, 6, 1, 33, 35

Using Visual Studio Code (VSC)

1. Install and Configure Java

   • Install Java support in Visual Studio Code.

2. Run Server and Client

   • Open the respective folders in VSC.
   • Click on Terminal -> New Terminal for each of the server and client directories.
   • Execute the same commands as mentioned above for CMD execution.

Scenarios

File Upload/Download System

• UPLOAD: Uploads a file from the client to the server.
• DOWNLOAD: Downloads a file from the server to the client.
• RENAME: Renames a file on the server.
• DELETE: Deletes a file on the server.
• SYNC: Synchronizes files between the client and the server.

Computation Server

• ADD: Adds two integers.
• SORT: Sorts a list of integers.
