1)form.jsp:

<html>
<form method="post" action="insert.jsp">
<table>
<tr><td>First Name:</td><td><input type="text" name="fname"></td></tr>
<tr><td>Last Name:</td><td><input type="text" name="lname"></td></tr>
<tr><td>Email:</td><td><input type="text" name="email"></td></tr>
<tr><td>Password:</td><td><input type="password" name="pass"></td></tr>
<tr><td>Confirm Password:</td><td><input type="password" name="cpass"></td></tr>
<tr><td>Date Of Birth</td><td><input type="text" name="dob"></td></tr>
<tr><td>Age:</td><td><input type="text" name="age"></td></tr>
<tr><td>Gender</td><td><input type="text" name="gender"></td></tr>
<tr><td>Address:</td><td><input type="text" name="address"></td></tr>
<tr><td>Country</td><td><input type="text" name="country"></td></tr>
<tr><td>State:</td><td><input type="text" name="state"></td></tr>
<tr><td>City</td><td><input type="text" name="city"></td></tr>
<tr><td>Telephone No:</td><td><input type="text" name="tno"></td></tr>
<tr><td>Mobile:</td><td><input type="text" name="mobile"></td></tr>
<tr><td></td><td><input type="submit" value="Submit"></td></tr>
</table>
</form>
</html>

2)insert.jsp:

<%@page import="java.sql.*,java.util.*"%>
<%
String fname=request.getParameter("fname");
String lname=request.getParameter("lname");
String email=request.getParameter("email");
String pass=request.getParameter("pass");
String cpass=request.getParameter("cpass");
String dob=request.getParameter("dob");
int age=Integer.parseInt(request.getParameter("age"));
String gender=request.getParameter("gender");
String address=request.getParameter("address");
String country=request.getParameter("country");
String state=request.getParameter("state");
String city=request.getParameter("city");
int telephone=Integer.parseInt(request.getParameter("tno"));
int mobile=Integer.parseInt(request.getParameter("mobile"));
        try{
         Class.forName("com.mysql.jdbc.Driver");
           Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/roseindia", "root", "root");
           Statement st=con.createStatement();
           int i=st.executeUpdate("insert into student(firstname,lastname,email,pass,confirm_pass,dob,age,gender,address,country,state,city,telephone,mobile) values('"+fname+"','"+lname+"','"+email+"','"+pass+"','"+cpass+"','"+dob+"',"+age+",'"+gender+"','"+address+"','"+country+"','"+state+"','"+city+"',"+telephone+","+mobile+")");
        out.println("Data is successfully inserted!");
        }
        catch(Exception e){
        System.out.println(e);
        e.printStackTrace();
        }
        %>

If the values will get inserted then you will get the message on the browser 'Data is successfully inserted' as we have specified in the above code.

Retrieve data using Statement

<%@page import="java.sql.*"%>
<table border=1>
<%
Class.forName("com.mysql.jdbc.Driver").newInstance();  
 Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/roseindia","root","root");  
Statement st=con.createStatement();
ResultSet rs=st.executeQuery("Select * from student");
if(rs.last()){
    %>
<tr><td><%=rs.getString(1)%></td><td><%=rs.getString(2)%></td><td><%=rs.getString(3)%></td><td><%=rs.getString(4)%></td><td><%=rs.getString(5)%></td><td><%=rs.getString(6)%></td><td><%=rs.getString(7)%></td><td><%=rs.getString(8)%></td><td><%=rs.getString(9)%></td><td><%=rs.getString(10)%></td><td><%=rs.getString(11)%></td><td><%=rs.getString(12)%></td><td><%=rs.getString(13)%></td><td><%=rs.getString(14)%></td></tr>
