Record user login and logout timing In JSP

In this section, we have developed a web application of maintain record of the user Login and Logout Time in JSP. Six files are used "home.jsp","login.jsp", "userloginmid.jsp", "welcome.jsp","logout.jsp" and "userstatus.jsp" in the code given below.

Brief description of the flow of application :

1). Create a webpage "home.jsp" to login the user and show the user login status link.

2). Create a webpage "login.jsp" to login the user.

3). Create a webpage "welcome.jsp" to display a message after successful login.

4). Create a webpage "userstatus.jsp" to display all the Login and Logout User status.

Step:1 Create Table for Database :

"userregister"

create table `userregister` (
`id` double ,
`username` varchar (50),
`password` varchar (50),
`first_name` varchar (50),
`last_name` varchar (50),
`city` varchar (50),
`state` varchar (50),
`country` varchar (50)
);

"admin"

create table `admin` (
`id` double ,
`userid` double ,
`intime` datetime ,
`outtime` datetime
);

Step:2 Create a web page "home.jsp" to login and display the user status link.

<HTML>
 <HEAD>
  <TITLE>Login Application</TITLE>
  </HEAD>
  <BODY>
  <br><br><br><br><br>
  <table align="center">
  <%
  if(session.getAttribute("username")!=null && session.getAttribute("username")!="")
  { 
  %>
  <tr><td align="left"><a href="logout.jsp">Click Here to Logout</a></td></tr>
  <%
  }
  else
  {
  %>
  <tr><td align="left"><a href="login.jsp">Click Here to User Login</a></td></tr>
  <%
  }
  %>
  <tr><td align="left">&nbsp;</td></tr>
  <tr><td align="left"><a href="userstatus.jsp">View Users Logon status</a></td></tr>
  </table>
  </BODY>
</HTML>

Step:3 To create a "login.jsp" to login the user

<html>
<head>
</head>
<body>
<br><br><br>
<table align="center" width="400px" border=0>
<tr><td align="right" width="300"><a href="home.jsp">Home</a></td></td></tr>
</table>
<table align="center"><tr><td colspan=2><h1>User Login</h2></td></tr></table>
<form name="loginform" method="post" action="userloginmid.jsp">
<table align="center" width="300px" style="border:1px solid #000000;" >
  <tr><td colspan=2>&nbsp;</td></tr>
  <tr>
  <td><b>Login Name</b></td>
  <td><input type="text" name="userName" value=""></td>
  </tr>
  <tr>
  <td><b>Password</b></td>
  <td><input type="password" name="password" value=""></td>
  </tr>
  <tr>
  <td>&nbsp;</td>
  <td><input type="submit" name="Submit" value="Submit"></td>
  </tr>
  <tr><td colspan=2>&nbsp;</td></tr>
</table>
</form>
</body>
</html>

Step:4 To create a "welcome.jsp" to display the message after succesful login the user.

<%@ page import="java.sql.*,java.util.*" %>
<html>
<body>
<br><br>
<table align="center" width="300px" border=0>
<%
String username="";
if(session.getAttribute("username")!=null && session.getAttribute("username")!="")
{
username=session.getAttribute("username").toString();
%>
  <tr>
 <td align="right" width="690"><a href="home.jsp">Home</a></td>
 <td align="right"><a href="logout.jsp">Logout</a></td>
  </tr>
<%
}
else
{
%>
  <tr>
 <td align="right"><a href="home.jsp">Home</a></td>
 <td align="right"><a href="login.jsp">Login</a></td>
  </tr>
<%
}
%>
<tr><td colspan=2>&nbsp;</td></tr>
<tr><td colspan=2><h1>Welcome <%=username%></h1></td></tr>
<table>
</body>
</html>

Step:5 Create a webpage "userstatus.jsp" to display the User Status .

<%@ page import="java.sql.*,java.util.*,java.text.*,java.text.SimpleDateFormat" %>
<html>
<head>
<TITLE>Login Application</TITLE>
</head>
<body>
<br><br>
<table align="center" width="400px" border=0>
  <%
  if(session.getAttribute("username")!=null && session.getAttribute("username")!="")
  {
  %>
  <tr>
  <td align="right" width="350"><a href="home.jsp">Home</a></td>
  <td align="right"><a href="logout.jsp">Logout</a></td>
  </tr>
  <%
  }
  else
  {
  %>
  <tr>
  <td align="right" width="350"><a href="home.jsp">Home</a></td>
  <td align="right"><a href="login.jsp">Login</a></td>
  </tr>
  <%
  }
  %>
</table>
<table width="400px" align="center" border=0> 
  <tr style="background-color:#D9B0D8;">
  <td align="center"><b>User Id</b></td>
  <td align="center"><b>Username</b></td>
  <td align="center"><b>Login</b></td>
  <td align="center"><b>Logout</b></td>
  </tr> 
<%

  }
  catch (Exception e)

  }
  %>
  <tr style="background-color:<%=strcolor%>;">

  e.printStackTrace();
}
%>
