JSP Registration Form + JDBC + MySQL Example


This article is a series of JSP tutorialsIn this article, we will build a simple Employee Registration module using JSP, JDBC, and MySQL database.
In this example, we will write JDBC code separate from the JSP page. JSP page we will be used only for presentation.

You can download the source code of this article from my GitHub repository. The link has given at end of this article.

In this article, we will design below  Employee Registration  JSP page and store Form parameters into the MySQL database:

Tools and technologies used

  • JSP - 2.2 +
  • IDE - STS/Eclipse Neon.3
  • JDK - 1.8 or later
  • Apache Tomcat - 8.5
  • JSTL - 1.2.1
  • MySQL - mysql-connector-java-8.0.13.jar

Development Steps

  1. Create an Eclipse Dynamic Web Project
  2. Add Dependencies
  3. Project Structure
  4. MySQL Database Setup
  5. Create a JavaBean - Employee.java
  6. Create a EmployeeDao.java
  7. Create a employeeregister.jsp
  8. Create a employeedetail.jsp
  9. Demo

1. Create an Eclipse Dynamic Web Project

To create a new dynamic Web project in Eclipse:
1. On the main menu select File > New > Project....
2. In the upcoming wizard choose Web > Dynamic Web Project.


3. Click Next.
4. Enter project name as "jsp-jdbc-mysql-example";5. Make sure that the target runtime is set to Apache Tomcat with the currently supported version. 

2. Add Dependencies

Add latest release of below jar files to lib folder.
  • jsp-api.2.3.1.jar
  • servlet-api.2.3.jar
  • mysql-connector-java-8.0.13.jar

3. Project Structure

Standard project structure for your reference - 

4. MySQL Database Setup

Let's create a database named "mysql_database" in MySQL. 
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;
SELECT * FROM mysql_database.employee; 

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

We will separate JDBC accessing code separate from JSP. So let's create an EmployeeDao class under net.javaguides.jsp.jdbc.database package and add the following code to it:
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/mysql_database?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 a employeeregister.jsp

Let's design an 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>
        <h1>Employee Register Form</h1>
        <form action="employeedetails.jsp" method="post">
            <table style="with: 50%">
                <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>
    </body>

    </html>

8. Create a employeedetail.jsp

After an employee successfully registered then this page shows a successful message on screen:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
 pageEncoding="ISO-8859-1"%>
<%@page import="net.javaguides.jsp.jdbc.database.*"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>

 <jsp:useBean id="employee"
  class="net.javaguides.jsp.jdbc.bean.Employee" />

 <jsp:setProperty property="*" name="employee" />

 <%
  EmployeeDao employeeDao = new EmployeeDao();
  int status = employeeDao.registerEmployee(employee);
  if (status > 0) {
   out.print("You are successfully registered");
  }
 %>
</body>
</html>
Note that in the above page, we have used JSP action tags. Read more about action tags here.

9. Demo

It's time to see a demo of the above development. Deploy this web application in the tomcat server.

    1. You need to add AUTO_INCREMENT to id column in the table. Check updated SQL script in this tutorial.
