Java MVC Web Application using JSP and Servlet

In this quick article, we’ll create a small web application that implements the Model View Controller (MVC) design pattern, using basic Servlets and JSPs.
Model-View-Controller (MVC) is a pattern used in software engineering to separate the application logic from the user interface. As the name implies, the MVC pattern has three layers.
The Model defines the business layer of the application, the Controller manages the flow of the application, and the View defines the presentation layer of the application.

Benefits of MVC in JSP and Servlet Web Application

  1. Minimizes HTML code in Servlet no more: out.println(…) in Servlet code.
  2. Minimize Java business logic in JSPs no more large scriptlets in JSP code
  3. It separates the presentation layer from the business layer
  4. The Controller performs the action of invoking the Model and sending data to View
  5. The Model is not even aware that it is used by some web application or a desktop application

Model-View-Controller (MVC)

  1. The Model Layer - This is the data layer which contains the business logic of the system, and also represents the state of the application. It’s independent of the presentation layer, the controller fetches the data from the Model layer and sends it to the View layer.
  2. The Controller Layer - Controller layer acts as an interface between View and Model. It receives requests from the View layer and processes them, including the necessary validations.
  3. The View Layer - This layer represents the output of the application, usually some form of UI. The presentation layer is used to display the Model data fetched by the Controller.

Java EE MVC Web Application using JSP and Servlet Example

To implement a web application based on MVC design pattern, we’ll create the Employee and EmployeeService classes – which will act as our Model layer.
EmployeeServlet class will act as a Controller, and for the presentation layer, we’ll create employees.jsp page.

Model Layer

Let's create the Employee and EmployeeService classes which will act as our Model layer.


package net.javaguides.mvc.model;

public class Employee {
    private int id;
    private String firstName;
    private String lastName;
    public Employee(int id, String firstName, String lastName) {
        super(); = id;
        this.firstName = firstName;
        this.lastName = lastName;
    public int getId() {
        return id;
    public void setId(int id) { = id;
    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;


package net.javaguides.mvc.service;

import java.util.Arrays;
import java.util.List;

import net.javaguides.mvc.model.Employee;

public class EmployeeService {

    public List < Employee > getEmployees() {
        return Arrays.asList(new Employee(1, "Ramesh", "Fadatare"), new Employee(2, "Tony", "Stark"),
            new Employee(3, "Tom", "Cruise"));

Controller Layer

Now let’s create our Controller class EmployeeServlet:
package net.javaguides.mvc.controller;


import javax.servlet.RequestDispatcher;
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.mvc.service.EmployeeService;

@WebServlet(name = "EmployeeServlet", urlPatterns = "/employees")

public class EmployeeServlet extends HttpServlet {

    private static final long serialVersionUID = 1 L;

    private EmployeeService employeeService = null;

    public void init() {
        employeeService = new EmployeeService();
    private void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.setAttribute("employees", employeeService.getEmployees());
        RequestDispatcher dispatcher = request.getRequestDispatcher("/WEB-INF/jsp/employees.jsp");
        dispatcher.forward(request, response);

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        processRequest(request, response);

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        processRequest(request, response);

View Layer

Next, let’s write our presentation layer employees.jsp:
<%@page import="java.util.List"%>
<%@page import="net.javaguides.mvc.model.Employee"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Student Record</title>
 <% List<Employee> employees = (List<Employee>)request.getAttribute("employees"); %>
 <table border="1" style="width: 50%" height="50%">
    <th>First Name</th>
    <th>Last Name</th>
   <!--   for (Todo todo: todos) {  -->
   <% for(Employee employee : employees){ %>
   <%} %>



In this tutorial, we’ve learned about the MVC i.e. Model View Controller architecture, and we focused on how to implement a simple example using JSP and Servlet.
