    13 |
  • MOJI works cross-platform. Including Windows, where the original client requires some modifications to run properly.
    • 14 |
  • MOJI is better suited for integration into an already existing online e-Learning system, especially if that system is Java based. It has exception handling and can be deployed using Maven.
    • 15 |
  • MOJI, internally, uses directory mode only. This detail should be negligible if you are starting from scratch. But please keep it in mind when porting your application from the Perl client.
    • 16 |
  • MOJI uses Java as its default language for programming sources.

20 | 21 | 22 | 23 | 24 | 25 | What is the meaning of optN, optX, etc.? 26 | 27 | 28 |

Detailed explanations of these parameters can be found in the source code of the original client. Here is a short summary:

29 |

optC: Comment string. Will show up on the results page so different results can be distinguished from each other.

30 |

optD: Directory mode.

31 |

optM: Do not treat source code passage as plagiarism if it is found at least this many times. Supplies an easy way to detect base/template code.

32 |

optN: Defines how many matches to display on the results page.

33 |

optX: Experimental feature support. Set to 1 to use the experimental MOSS server.

34 | 35 | 36 | 37 | 38 | 39 | Development 40 | 41 | 42 | 43 | Why are there runtime exceptions after compiling successfully? 44 | 45 | 46 |

47 | If you get runtime exceptions, you are trying to call methods of the socket client in the wrong order -- for example by uploading files before authenticating with the server. 48 |

Preparation 36 | 37 | MOJI requires some kind of Moss-compatible directory structure to distinguish 38 | between different students. 39 | 40 | To achieve this, copy all student source codes to a directory where each 41 | subdirectory contains the source code of a single student. 42 | 43 | A valid directory containing student solutions might look like this: 44 | 45 | 46 | solution_directory 47 | |- student1 48 | |- classA.java 49 | |- ... 50 | |- student2 51 | |- ... 52 | |_ student3 53 | |- ... 54 | 55 | ### 2. Download the JAR (or build it yourself) and include it in your project. 56 | 57 | ### 3. Create a new socket client object to communicate with the Moss server. 58 | 59 | ## Example code 60 | 61 | import java.io.File; 62 | import java.util.Collection; 63 | import java.net.URL; 64 | import org.apache.commons.io.FileUtils; 65 | import it.zielke.moji.SocketClient; 66 | 67 | public class QuickStart { 68 | public static void main(String[] args) throws Exception { 69 | // a list of students' source code files located in the prepared 70 | // directory. 71 | Collection files = FileUtils.listFiles(new File( 72 | "C:\\temp\\solution_directory"), new String[] { "java" }, true); 73 | 74 | // a list of base files that was given to the students for this 75 | // assignment. 76 | Collection baseFiles = FileUtils.listFiles(new File( 77 | "C:\\temp\\base_directory"), new String[] { "java" }, true); 78 | 79 | //get a new socket client to communicate with the Moss server 80 | //and set its parameters. 81 | SocketClient socketClient = new SocketClient(); 82 | 83 | //set your Moss user ID 84 | socketClient.setUserID("123456789"); 85 | //socketClient.setOpt... 86 | 87 | //set the programming language of all student source codes 88 | socketClient.setLanguage("java"); 89 | 90 | //initialize connection and send parameters 91 | socketClient.run(); 92 | 93 | // upload all base files 94 | for (File f : baseFiles) { 95 | socketClient.uploadBaseFile(f); 96 | } 97 | 98 | //upload all source files of students 99 | for (File f : files) { 100 | socketClient.uploadFile(f); 101 | } 102 | 103 | //finished uploading, tell server to check files 104 | socketClient.sendQuery(); 105 | 106 | //get URL with Moss results and do something with it 107 | URL results = socketClient.getResultURL(); 108 | System.out.println("Results available at " + results.toString()); 109 | } 110 | } 111 | 112 | ## Tests 113 | 114 | To execute all tests, simply run 115 | 116 | mvn test 117 | 118 | ## Documentation 119 | 120 | http://www.zielke.it/moji/ 121 | 122 | ## Attribution 123 | 124 | This software communicates with 125 | Moss by Alex Aiken of 126 | Stanford University. 127 | MOJI is not in any way affiliated with Moss. 128 | 129 | ## License 130 | 131 | MOJI is under MIT License.
