1)login.jsp:

<html>
<script>
function register(){
    var f=document.form;
    f.method="post";
    f.action='reg.jsp';
    f.submit();
}
function validate(){
var username=document.form.user.value;
var password=document.form.pass.value;
if(username==""){
 alert("Enter Username!");
  return false;
}
if(password==""){
 alert("Enter Password!");
  return false;
}
return true;
}
</script>
<form name="form" method="post" action="check.jsp" onsubmit="javascript:return validate();">
<table>
<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>

</table>
</form>
</html>

2)check.jsp:

<%@page import="java.sql.*"%>

<%
String user=request.getParameter("user");
String pass=request.getParameter("pass");
 Class.forName("com.mysql.jdbc.Driver").newInstance();
    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;
          while(rs.next())
          {

                   count++;
          }

                    if(count>0)
          {
            out.println("welcome "+user);
          }
          else
          {
                       response.sendRedirect("login.jsp");
          }
