Servlet sendRedirect to html:


function validate(){
var username=document.form.user.value;
var password=document.form.pass.value;
 alert("Enter Username!");
  return false;
 alert("Enter Password!");
  return false;
return true;
<form name="form" method="post" action="http://localhost:8080/examples/Login" onsubmit="javascript:return validate();">
<tr><td>Username:</td><td><input type="text" name="user"></td></tr>
<tr><td>Password:</td><td><input type="password" name="pass"></td></tr>
<tr><td></td><td><input type="submit" value="Submit"></td></tr>


import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Login extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { 

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out=response.getWriter();
        String user=request.getParameter("user");
String pass=request.getParameter("pass");
    Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root");  
           Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("select * from login where username='"+user+"' and password='"+pass+"'");
int count=0;


            out.println("welcome "+user);
