12. Develop a JSP Application to Authenticate User Login as per the Registration Details. If Login Success then forward User to Index Page otherwise show Login failure Message.


Listing 1: Login Form

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1>Login Page</h1>
        <center>
            <h2>Signup Details</h2>
            <form action="LoginCheck.jsp" method="post">
            <br/>Username:<input type="text" name="username">
            <br/>Password:<input type="password" name="password">
            <br/><input type="submit" value="Submit">
            </form>
        </center>
    </body>
</html>


Listing 2: LoginCheck.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        <%
        String username=request.getParameter("username");
        String password=request.getParameter("password");
       
        if((username.equals("anurag") && password.equals("jain")))
            {
            session.setAttribute("username",username);
            response.sendRedirect("Home.jsp");
            }
        else
            response.sendRedirect("Error.jsp");
        %>
    </body>
</html>


Listing 3: Home.jsp

<%@page contentType="text/html" pageEncoding="UTF-8" errorPage="Error.jsp"%>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>       
        <br/><br/><br/><br/><br/>
        <center>
            <h2>
            <%
            String a=session.getAttribute("username").toString();
            out.println("Hello  "+a);
            %>
            </h2>

            <br/><br/><br/><br/><br/>
        <a href="logout.jsp">Logout</a>

    </head>
    <body>
        <%

        session.removeAttribute("username");
        session.removeAttribute("password");
        session.invalidate();
        %>
        <h1>Logout was done successfully.</h1>
        
    </body>
</html>


Listing 5: Error.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
