It is the serializable class of Java that is used to contain data in object patterns, using we can send data easily from one platform to another using a secure way.

it is used to provide MVC Design patterns to Java Program Code.

MVC means MODEL, VIEW, and Controller.

MODEL means Database Layer which is used to perform a database operation, JAVA Bean class will work in Database Layer.

View:-  It is used to design a web page using JSP, it is also called User Access Layer

Controller:- it will work as an intermediate between Model and Views. we will write program code or program logic also in Controller. Servlet Class will be used to Create a Controller.

The flow of MVC:-

In MVC Design Pattern First Controller will be called after that View and Model Layer Will be Loaded into An Application.

1)   Controller  ------->  2) View  ---------->  3) Model

Step for MVC:-

1) Create a JSP page  to design view
2)  Create Servlet  to design a controller
3)  Create JAVA Beans Class Define Property to create a model

Property is used to contain data of data members using getter and setter blocks.

JAVA BEAN CLASS is also Called POJO CLASS in Hibernate


1) Code of JSP Web Page or View:-

<%@ 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>Insert title here</title>
<h1>Staff Registration Form</h1>
<form action="../StaffSerNew" method="post">

<input type="text" name="txtsid" placeholder="Enter staff ID" />
<input type="text" name="txtpass" placeholder="Enter password" />
<input type="text" name="txtfname" placeholder="Enter fullname" />
<input type="text" name="txtrole" placeholder="Enter role" />
<input type="submit" name="btnsubmit" value="Click" />

<a href="stafflogin.jsp">Login Here</a>

2) Code of Controller Class or Servlet:-

package controller;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;

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 model.Staff;;
 * Servlet implementation class StaffSer
@WebServlet(name = "StaffSerNew", urlPatterns = { "/StaffSerNew" })
public class StaffSer extends HttpServlet {
private static final long serialVersionUID = 1L;
     * @see HttpServlet#HttpServlet()
    public StaffSer() {
        // TODO Auto-generated constructor stub

* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.getWriter().append("Served at: ").append(request.getContextPath());

* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
Staff obj = new Staff();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/crm","root","");
Statement st = conn.createStatement();
int res = st.executeUpdate("insert into staff(staffid,password,fullname,role) values('"+obj.getStaffid()+"','"+obj.getPassword()+"','"+obj.getFullname()+"','"+obj.getRole()+"')");
out.print("Data Submitted Successfully");
catch(Exception ex)


3) Code of Model Class or Bean Class:-

package model;

public class Staff {
private String staffid;
private String password;
private String fullname;
private String role;
public String getStaffid() {
return staffid;
public void setStaffid(String staffid) {
this.staffid = staffid;
public String getPassword() {
return password;
public void setPassword(String password) {
this.password = password;
public String getFullname() {
return fullname;
public void setFullname(String fullname) {
this.fullname = fullname;
public String getRole() {
return role;
public void setRole(String role) {
this.role = role;
