a)	Develop a simple JSP application values obtained from the use of intrinsic objects of various types.
Code :-
index.jsp   -
<html>
<head><title>Index Page</title></head>
<body>
    <form action="welcome.jsp">
        Enter Username : <input type="text" name="uname"></br>
        <input type="submit" value="go">
    </form>
</body>
</html>

welcome.jsp   -
<%@page import="java.io.PrintWriter"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Implicit Objects Example</title>
</head>
<body>
    <%-- response object --%>
    <%
    PrintWriter pw =  response.getWriter();
    pw.print("<h1><strong>"+" Welcome "+"</strong></h1>");
    %><br><br>
    <%-- request object --%>
    <strong>Request example - User : </strong><%=request.getParameter("uname").toString() %><br><br>
    <%-- out object --%>
    <strong>Out object prints: </strong><%out.print("This is an example");%><br><br>
    <%-- config object --%>
    <strong>Config example - servlet name: </strong><%=config.getServletName()%><br><br>
    <%-- application object --%>
    <strong>Application example - server info: </strong><%=application.getServerInfo()%><br><br>
    <%-- page object --%>
    <strong>Page example - page name: </strong><%=page.getClass().getName()%><br><br>
    <%-- session object --%>
    <strong>Session example - creation time: </strong><%=session.getCreationTime()%><br><br>
    <%-- pageContext object --%>
    <%-- pageContext.setAttribute("Test", "Test Value"); --%>
    <strong>PageContext example - class name: </strong><%=pageContext.getClass().getName() %><br><br>
</body>
</html>


b)	Create a servlet for a login page if the username and password are correct then it says message “Hello <username>” else a message “Login Failed”.
Code :-
index.html   -
<body>
<form method=”get” action=”hello”>
<legend>Login Form</legend>
            	Username : <input type="text" name="username"><br/>
            	Password : <input type="password" name="password"><br/>
            	<input type="submit" value="Submit" name="submit">
</form>
</body>
hello.java –
out.println("<body>");
            String user=request.getParameter("username");
            String pass=request.getParameter("password");
            if(user.equals("ABC") && pass.equals("abc123"))
                out.println("<h1>"+"Hello "+user+" !!"+"</h1>");
            else if(user.equals("DEF") && pass.equals("def123"))
                out.println("<h1>"+"Hello "+user+" !!"+"</h1>");
            else if(user.equals("GHI") && pass.equals("ghi123"))
                out.println("<h1>"+"Hello "+user+" !!"+"</h1>");
            else
                out.println("<h1>"+"Login Failed !"+"</h1>");
            out.println("</body>");
