| Step 1: Design code for Login Page |
<html>
<head>
<title>userloginpage</title>
<SCRIPT LANGUAGE="javascript"> function usermeth()
{
var user=document.Login_Page.usr.value;
var pass=document.Login_Page.pswd.value;
if(user.length==0) { alert("Please Enter the username");
document.Login_Page.usr.focus(); return false;
}
if(pass.length==0){ alert("Please Enter the password");
document.Login_Page.pswd.focus(); return false;
} return true;
}
</script></head><body>
<form name="Login_Page" method="Post" action="loginjsp.jsp"
onsubmit="javascript: return usermeth()">
<center><font color='green' size=4>Login your Authentication:</font><br><br>
Enter UserName<input type="text" name="usr">
<br>
Enter PassWord<input type="password" name="pswd"><br>
<input type="submit" value="`````Submit`````">
</center>
</form>
</body>
</html>

| Step 2: Design code for Access values from DB |
<%@ page import="java.sql.*" %>
<html>
<head>
<title>LoginJSP</title>
</head>
<body>
<form>
<%
String username=request.getParameter("usr");
String password=request.getParameter("pswd");
String sql="select * from logintb";
Connection con;
ResultSet rs;
try
{
Class.forName("com.mysql.jdbc.Driver");
}
catch(ClassNotFoundException e)
{
System.out.println("Class Error");
}
try
{
con=DriverManager.getConnection("jdbc:mysql://localhost:3306/vijikumar","root","sun");
Statement st = con.createStatement();
rs=st.executeQuery(sql);
while(rs.next())
{
String us=rs.getString(1);
String ps=rs.getString(2);
if(us.equals(username)&&ps.equals(password))
{
%>
<jsp:forward page="logsuc.html"/>;
<%
}
else
{ %>
<jsp:forward page="logfail.html"/>;
<% }
}
}
catch(SQLException e)
{
System.out.println(e.getMessage());
}
%>
</form>
</body>
</html>

<head>
<title>LoginSucess</title>
</head>
<body>
<h2><Font color="green">LoginSuccessfully</Font></h2>
</body>
</html>
|
 |
