first you should to create a jsp
like login.jsp
<%@page language="java"%>
<html>
<head>
<title>fill form</title>
<body>
<form action ="loginservlet.java" mrthod=post>
<input type =text ,name=username ,value="">
<imput type =password,name =password,value="">
</form>
</body>
....
loinservlet.java
import java.io.*;
import javax.servlet.*;
import java.sql.*;
class Loginservlet extends HttpSevlet
{
public void dopost(HttpServletRequest request,
HttpServletResponse response)throws
ServletException,IOException
{
String connectionURL
= "jdbc:mysql://192.168.10.59/datbasename";
Connection connection=null;
ResultSet rs;
String userName=new String("");
String passwrd=new String("");
response.setContentType("text/html");
try {
Class.forName("com.mysql.jdbc.Driver");
connection = DriverManager.getConnection
(connectionURL, "root", "root");
String sql = "select user,password from User";
Statement s = connection.createStatement();
s.executeQuery (sql);
rs = s.getResultSet();
while (rs.next ()){
username=rs.getString("user");
passwrd=rs.getString("password");
}
rs.close ();
s.close ();
}catch(Exception e){
System.out.println("Exception is ;"+e);
}
if(userName.equals(request.getParameter("usernmae"))
&&
passwrd.equals(request.getParameter
("password"))){
out.println("User Authenticated");
}
else{
out.println("You are not an authentic person");
}
}
}
