OnlineExamination

--Creating a simple J2EE application that performs CRUD (Create Read Update Delete) operations for conducting online examination using Jsp, Servlet and MySQL. -- It contains the knowledge for the followings: * MVC(Model View Controller) * DAO(Data Access Object) * REST(Representational State Transfer) * CRUD(Create Read Update Delete) * MySQL(Structured Query Language) * Basic understanding of JSP, Servlets, Java Coding.

Prerequisites

For this tutorial, we will need the following tools: (The older or newer version should also works). Moreover, basic Java knowledge is assumed. --Eclipse IDE for Java EE Developers --Apache Tomcat v7 or later --MySQL Community Server and MySQL Workbench (GUI Tool) --MySQL Connector for Java --jstl.jar and standard.jar.

Contains

--Create the database First, lets create the database and table for the pojo classes mentioned below

--POJO classes / Model Classes Exam (Model class for exam, having variables and getter setter related to the Test) Institute (Model class for Institute, having variables and getter setter related to the Institute) Login (Model class for Login, having variables and getter setter related to the Login credentials) QuestionPaper (Model class for Question Paper, having variables and getter setter related to the Question Paper) Report (Model class for Report, having variables and getter setter related to the Report generation) Student (Model class for Student, having variables and getter setter related to the student)

--Creating DB Connection Utility Create a new class in your package and name it DbUtility.java. This class handles the database connection to our MySQL server. In this class, we read a .properties file which contains the information necessary for the connection.

--Property File
Create the properties file directly under the src folder. Create a new file, name it db.properties. Put the following information. #Database Credentials #Fri Jun 16 11:11:29 IST 2017 driver=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/onlineexaminationsystem user=root password=root

--Creating Data Access Objects (DAO) Next, create Data Access Object classes. It contains the logic for database operation.

• AdminDAO { public List getAllStudents(); public void deleteStudent(String studentId ); public List getAllInstitutes(); public void deleteInstitute(String instituteId); }

• InstituteDAO { public String registerInstitute(Institute institute); public List getAllStudents(String instituteMailId); public List getAllExams(String instituteMailId); public void deleteExam(String examId ); public ArrayList uploadExam(Exam exam); public String uploadQuestion(QuestionPaper question); public Report calculateResult(String ans1, String ans2, String ans3, String ans4, String ans5, String studentMailId); }

• StudentDAO { public String registerStudent(Student student); public List getAllInstitutes(String studentMailId); public List getAllExams(String instituteId, String studentMailId) ; public List getAllQuestions(String examId); }

--Creating Controllers Finally, create a new Servlets inside the project and name it Controller.java

• AdminController
• InstituteController
• StudentController
• StudentRegisterController
• InstituteRegisterController
• UserController

--Creating View Now, it’s time for us to create the jsp, the view for our application. Under the WebContent folder.
