1. Create an Eclipse Dynamic Web Project
To create a new dynamic Web project in Eclipse:
1. On the main menu selectFile > New > Project....
2. In the upcoming wizard chooseWeb > Dynamic Web Project.
3. ClickNext.
4. Enter project name as "jsp-servlet-jdbc-mysql-example";
5. Make sure that the target runtime is set to Apache Tomcat with the currently supported version.
2. Add Dependencies
Add the latest release of below jar files to the lib folder.
- jsp-api.2.3.1.jar
- servlet-api.2.3.jar
- mysql-connector-java-8.0.13.jar
- jstl-1.2.jar
3. Project Structure
Standard project structure for your reference -
4. MySQL Database Setup
Let's create a database named "employees" in MySQL. Now, let's create an employee table using below DDL script:
CREATE TABLE `employee` ( `id` int(3) NOT NULL AUTO_INCREMENT, `first_name` varchar(20) DEFAULT NULL, `last_name` varchar(20) DEFAULT NULL, `username` varchar(250) DEFAULT NULL, `password` varchar(20) DEFAULT NULL, `address` varchar(45) DEFAULT NULL, `contact` varchar(45) DEFAULT NULL, PRIMARY KEY ( `id` ) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
5. Create a JavaBean - Employee.java
Let's create an Employee JavaBean class which we will use in JSP action tags.
package net.javaguides.jsp.jdbc.bean; import java.io.Serializable; /** * JavaBean class used in jsp action tags. * @author Ramesh Fadatare */ public class Employee implements Serializable { /** * */ private static final long serialVersionUID = 1 L; private String firstName; private String lastName; private String username; private String password; private String address; private String contact; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this .firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this .lastName = lastName; } public String getUsername() { return username; } public void setUsername(String username) { this .username = username; } public String getPassword() { return password; } public void setPassword(String password) { this .password = password; } public String getAddress() { return address; } public void setAddress(String address) { this .address = address; } public String getContact() { return contact; } public void setContact(String contact) { this .contact = contact; } }
6. Create an EmployeeDao.java
Let's create EmployeeDao classwhich contains JDBC code to connect with MySQL database. Add the following code to anEmployeeDaoclass:
package net.javaguides.jsp.jdbc.database; import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; import net.javaguides.jsp.jdbc.bean.Employee; public class EmployeeDao { public int registerEmployee(Employee employee) throws ClassNotFoundException { String INSERT_USERS_SQL = "INSERT INTO employee" + " (id, first_name, last_name, username, password, address, contact) VALUES " + " (?, ?, ?, ?, ?,?,?);" ; int result = 0; Class .forName( "com.mysql.jdbc.Driver" ); try (Connection connection = DriverManager .getConnection( "jdbc:mysql://localhost:3306/employees?useSSL=false" , "root" , "root" ); // Step 2:Create a statement using connection object PreparedStatement preparedStatement = connection.prepareStatement(INSERT_USERS_SQL)) { preparedStatement.setInt(1, 1); preparedStatement.setString(2, employee.getFirstName()); preparedStatement.setString(3, employee.getLastName()); preparedStatement.setString(4, employee.getUsername()); preparedStatement.setString(5, employee.getPassword()); preparedStatement.setString(6, employee.getAddress()); preparedStatement.setString(7, employee.getContact()); System .out.println(preparedStatement); // Step 3: Execute the query or update query result = preparedStatement.executeUpdate(); } catch (SQLException e) { // process sql exception printSQLException(e); } return result; } private void printSQLException(SQLException ex) { for (Throwable e: ex) { if (e instanceof SQLException) { e.printStackTrace(System .err); System .err.println( "SQLState: " + ((SQLException) e).getSQLState()); System .err.println( "Error Code: " + ((SQLException) e).getErrorCode()); System .err.println( "Message: " + e.getMessage()); Throwable t = ex.getCause(); while (t != null) { System .out.println( "Cause: " + t); t = t.getCause(); } } } } }

7. Create an EmployeeServlet.java
Let's create an EmployeeServlet class to process HTTP request parameters and redirect to the appropriate JSP page after request data stored in the database:
package net.javaguides.employeemanagement.web; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import net.javaguides.employeemanagement.dao.EmployeeDao; import net.javaguides.employeemanagement.model.Employee; /** * @email Ramesh Fadatare */ @WebServlet( "/register" ) public class EmployeeServlet extends HttpServlet { private static final long serialVersionUID = 1 L; private EmployeeDao employeeDao; public void init() { employeeDao = new EmployeeDao(); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String firstName = request.getParameter( "firstName" ); String lastName = request.getParameter( "lastName" ); String username = request.getParameter( "username" ); String password = request.getParameter( "password" ); String address = request.getParameter( "address" ); String contact = request.getParameter( "contact" ); Employee employee = new Employee(); employee.setFirstName(firstName); employee.setLastName(lastName); employee.setUsername(username); employee.setPassword(password); employee.setContact(contact); employee.setAddress(address); try { employeeDao.registerEmployee(employee); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } response.sendRedirect( "employeedetails.jsp" ); } }
8. Create a employeeregister.jsp
Let's design employee registration HTML form with the following fields:
- firstName
- lastName
- username
- password
- address
- contact
<%@ page language= "java" contentType= "text/html; charset=ISO-8859-1" pageEncoding= "ISO-8859-1" %> <!DOCTYPE html> <html> <head> <meta charset= "ISO-8859-1" > <title>Insert title here</title> </head> <body> <div align= "center" > <h1>Employee Register Form</h1> <form action= " <%= request.getContextPath() %>/register" method= "post" > <table style= " with: 80% " > <tr> <td>First Name</td> <td><input type= "text" name= "firstName" /></td> </tr> <tr> <td>Last Name</td> <td><input type= "text" name= "lastName" /></td> </tr> <tr> <td>UserName</td> <td><input type= "text" name= "username" /></td> </tr> <tr> <td>Password</td> <td><input type= "password" name= "password" /></td> </tr> <tr> <td>Address</td> <td><input type= "text" name= "address" /></td> </tr> <tr> <td>Contact No</td> <td><input type= "text" name= "contact" /></td> </tr> </table> <input type= "submit" value= "Submit" /> </form> </div> </body> </html>
9. Create an employeedetails.jsp
After an employee successfully registered then this page show a successful message on screen:
<%@ page language= "java" contentType= "text/html; charset=ISO-8859-1" pageEncoding= "ISO-8859-1" %> <%@page import= "net.javaguides.employeemanagement.dao.*" %> <!DOCTYPE html> <html> <head> <meta charset= "ISO-8859-1" > <title>Insert title here</title> </head> <body> <h1>User successfully registered!</h1> </body> </html>
Note that in the above page, we have used JSP action tags. Read more about action tags here.
10. Demo
It's time to see a demo of the above development. Deploy this web application in tomcat server.
