implement multi-thread server to handle concurrent requests from several clients to query or operate a dictionary file on server. 4 | 5 | More details about this project and the code can be found in [Assignment1.pdf]() and [Report.pdf]() 6 | 7 | There are two ways to execute this project (Need parameters to run main function): 8 | 9 | - Open `DictionaryMultithreadSC` in IntelliJ IDEA, run the DictionaryServer.java with running parameters in form of ` ` such as `2029 dic.txt` and the DictionaryClient.java with running parameters in the form of ` ` such as `localhost 2029`. 10 | 11 | - Run the `jar` package in `Jar Package as` in cmd/shell as `java –jar DictionaryServer.jar ` and `java –jar DictionaryClient.jar ` 12 |

-------------------------------------------------------------------------------- /Project2/Version4.0/README.md: -------------------------------------------------------------------------------- 1 | Please refer to Assignment2-Report-WalidMoustafa.pdf for more details. 2 | 3 | This assignment is about implementing a distributed Whiteboard application. The whiteboard will be shared by several users connected to a central server using Java RMI (Remote Method Invocation) framework. The implemented architecture is a star schema with a simple messaging server in the centre and several desktop clients exchanging and synchronizing user interface as well as control events via RMI function calls the central server. The first user connects to the server is granted the Admin role which authorizes her to receive following users requests-to-join and decide which requests to accept and grant access to the shared whiteboard and which requests to simply revoke and bounce out of the board. Even authorized board users can be bounced out of the whiteboard at any time by the Admin user. Moreover, when the admin user quits the application, all connected board users are sent a notification message and all are bounced out and the board is cleared out. By the end of a board session (which normally happens when all users quit or the Admin user terminates the running whiteboard session), the board server discards all the session data, but does NOT shutdown. Instead, the board server keeps waiting for the first user to connect to be granted the Admin role and start a brand new whiteboard session. 4 | -------------------------------------------------------------------------------- /Project2/Version4.0/pom.xml: -------------------------------------------------------------------------------- 1 | 3 | 4.0.0 4 | 5 | com.walidmoustafa.board 6 | distributed-board 7 | 1.0 8 | jar 9 | 10 | distributed-board 11 | http://maven.apache.org 12 | 13 | 14 | UTF-8 15 | 16 | 17 | 18 | 19 | org.slf4j 20 | slf4j-log4j12 21 | 1.7.5 22 | 23 | 24 | junit 25 | junit 26 | 3.8.1 27 | test 28 | 29 | 30 | 31 | 32 | 33 | 34 | org.apache.maven.plugins 35 | maven-compiler-plugin 36 | 3.2 37 | 38 | 1.8 39 | 1.8 40 | 41 | 42 | 43 | 44 | org.apache.maven.plugins 45 | maven-assembly-plugin 46 | 2.4 47 | 48 | 49 | jar-with-dependencies 50 | 51 | 52 | 53 | true 54 | com.walidmoustafa.board.App 55 | 56 | 57 | 58 | 59 | 60 | assemble-all 61 | package 62 | 63 | single 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | -------------------------------------------------------------------------------- /Project2/Version4.0/src/main/java/com/walidmoustafa/board/gui/BoardEvent.java: -------------------------------------------------------------------------------- 1 | package com.walidmoustafa.board.gui;/* 2 | * Name: Walid Moustafa 3 | * Student ID: 563080 4 | * Subject: COMP90015 - Distributed Systems 5 | * Assignment: Assignment 2 - Distributed Whiteboard 6 | * Project: com.walidmoustafa.board.gui.BoardServer 7 | * File: com.walidmoustafa.board.gui.BoardEvent.java 8 | */ 9 | 10 | import java.awt.*; 11 | import java.io.Serializable; 12 | import java.util.ArrayList; 13 | 14 | 15 | public class BoardEvent implements Serializable { 16 | 17 | private static final long serialVersionUID = 1L; 18 | public int eventID; 19 | public final String eventType; 20 | public String userID; 21 | public ArrayList userList; 22 | public int currentShape; 23 | public int currentMode; 24 | public Color currentColor; 25 | public boolean erasing; 26 | public int eraserSize; 27 | public Point startPoint; 28 | public Point endPoint; 29 | public ArrayList points; 30 | public ArrayList textInput; 31 | public ArrayList shapes; 32 | 33 | public BoardEvent(String eType) { 34 | eventType = eType; 35 | } 36 | 37 | } 38 | -------------------------------------------------------------------------------- /Project2/Version4.0/src/main/java/com/walidmoustafa/board/gui/BoardServer.java: -------------------------------------------------------------------------------- 1 | package com.walidmoustafa.board.gui;/* 2 | * Name: Walid Moustafa 3 | * Student ID: 563080 4 | * Subject: COMP90015 - Distributed Systems 5 | * Assignment: Assignment 2 - Distributed Whiteboard 6 | * Project: com.walidmoustafa.board.App 7 | * File: com.walidmoustafa.board.gui.BoardServer.java 8 | */ 9 | 10 | import java.rmi.Remote; 11 | import java.rmi.RemoteException; 12 | import java.util.ArrayList; 13 | 14 | 15 | public interface BoardServer extends Remote { 16 | 17 | String joinBoard(String candidateID) throws RemoteException; 18 | 19 | String getAdmin() throws RemoteException; 20 | 21 | void approveUser(String userID) throws RemoteException; 22 | 23 | void bounceUser(String userID) throws RemoteException; 24 | 25 | void addBoardEvent(BoardEvent event) throws RemoteException; 26 | 27 | ArrayList getBoardEvents(int startFrom) throws RemoteException; 28 | 29 | } 30 | -------------------------------------------------------------------------------- /Project2/Version4.0/src/main/java/com/walidmoustafa/board/gui/Eraser.java: -------------------------------------------------------------------------------- 1 | package com.walidmoustafa.board.gui;/* 2 | * Name: Walid Moustafa 3 | * Student ID: 563080 4 | * Subject: COMP90015 - Distributed Systems 5 | * Assignment: Assignment 2 - Distributed Whiteboard 6 | * Project: com.walidmoustafa.board.App 7 | * File: com.walidmoustafa.board.gui.Eraser.java 8 | */ 9 | 10 | import java.awt.Color; 11 | import java.awt.Graphics; 12 | import java.awt.Point; 13 | import java.io.Serializable; 14 | import java.util.ArrayList; 15 | 16 | 17 | public class Eraser implements Shape, Serializable { 18 | private static final int seed = 3; 19 | private static final long serialVersionUID = 1L; 20 | private int size = 1; 21 | private ArrayList points = new ArrayList<>(); 22 | 23 | public Eraser(ArrayList pts, int size) { 24 | this.size = size; 25 | points = pts; 26 | } 27 | 28 | private static void erasePoint(Graphics gfx, int size, Point point) { 29 | size = size * seed; 30 | int x = (point.x - size) > 0 ?
