Step 1: Create a project as in the picture then
create web.xml as follows:
<?xml version="1.0"
encoding="UTF-8"?>
<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml
/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com
/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>WebApp</display-name>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>
Step 2: Create login page under WebContent directory
as follow:
<%@ page
language="java" contentType="text/html;
charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html
PUBLIC "-//W3C//DTD
HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1">
<title>. : User Login
Page : . </title>
</head>
<body>
<br /><br /><br /><br /><br /><br /><br /><br />
<center>
<form action="loginAction.jsp"
name="loginForm" method="post">
<table style="width:250px;" bgcolor="#FFFFFF"
border="0" bordercolor="#FF3300">
<tr>
<td colspan="3"
bgcolor="#CCCCCC" align="center"
style="height:30px;"> Login Form </td>
</tr>
<tr>
<td style="height:30px;"> User Name </td>
<td> : </td>
<td> <input type="text"
name="userName" /> </td>
</tr>
<tr>
<td style="height:30px;"> Password </td>
<td> : </td>
<td> <input type="password"
name="password" />
</tr>
<tr>
<td colspan="3"
align="center" bgcolor="#993300"
style="height:30px;"> <input type="submit" value="Submit"
name="submit" /> </td>
</tr>
</table>
</form>
</center>
</body>
</html>
Step 3: Create DbConnection class under armukul.blogspot.com
package as follows:
package armukul.blogspot.com;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DbConnection {
private
static Connection conn = null;
public
static Connection getConnection(){
if
(conn != null)
return
conn;
else{
try{
// Create string of JDBC driver
"com.mysql.jdbc.Driver".
String
dirver = "com.mysql.jdbc.Driver";
// Create string of connection url //
String
jdbcUrl = "jdbc:mysql://localhost:3306/";
String
dbName = "stock";
String
dbUser = "root";
String
dbPass = "";
//load
jdbc driver
Class.forName(dirver);
/* Create a connection by using
getConnection() method that takes parameters of
string type connection url, user name and password to connect to database. */ conn = DriverManager.getConnection(jdbcUrl + dbName, dbUser, dbPass);
string type connection url, user name and password to connect to database. */ conn = DriverManager.getConnection(jdbcUrl + dbName, dbUser, dbPass);
System.out.println
("Connection established");
}catch
(ClassNotFoundException cnfe){
cnfe.printStackTrace();
}
catch (SQLException sqle){
sqle.printStackTrace();
}
return
conn;
}
//end of else
}//end
of connect method
public
static boolean colseConnection(Connection c){
try{
c.close();
return
true;
}
catch (SQLException sqle){
sqle.printStackTrace();
return
false;
}
}
} //end of DbConnection class
Step 4: Create LoginAction.jsp as follows:
<%@ page
language="java" contentType="text/html;
charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page
import="armukul.blogspot.com.*" %>
<%@ page
import="java.sql.*" %>
<!DOCTYPE html
PUBLIC "-//W3C//DTD
HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1">
<title> Login Action </title>
</head>
<body>
<%
String user =
request.getParameter("userName");
String pass =
request.getParameter("password");
// call getConnection method
try{
Connection
con = DbConnection.getConnection();
Statement
st = con.createStatement();
String
sql = "select * from login where userName ='"+user+"' and
password ='"+pass+"'";
ResultSet
rs = st.executeQuery(sql);
int count = 0;
while (rs.next()){
out.println
(user);
count++;
}
if (count > 0){
response.sendRedirect("index.jsp");
}
else {
response.sendRedirect("login.jsp");
}
// colse db
connection
//DbConnection.colseConnection(con);
} catch (SQLException
sqle){
sqle.printStackTrace();
}
%>
</body>
</html>
Step 5: Create index.jsp as follows:
<%@ page
language="java" contentType="text/html;
charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page
import="armukul.blogspot.com.*" %>
<%@ page
import="java.sql.*" %>
<!DOCTYPE html
PUBLIC "-//W3C//DTD
HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1">
<title>Home Page</title>
</head>
<body>
<br /><br /><br /><br /><br /><br /><br /><br />
<center>
<%
String user =
request.getParameter("userName");
%>
Registration is Successfull.
Welcome to <%=user %>
</center>
</body>
</html>
Step 6: To run the project:
i) Right click on
your project then click on Run on Server from Run as option or
ii)
Type http://localhost:8080/WebApp
