Advanced Java Programming Practical 23
Question 1
Develop servlet program to display various details about session using HttpSession methods.
SessionDemo.java
Java
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionDemo extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Session Details</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Session Details</h1>");
HttpSession hs=request.getSession(true);
Date d1=new Date(hs.getCreationTime());
Date d2=new Date(hs.getLastAccessedTime());
out.println("Session id: "+hs.getId()+"<br>");
out.println("Session creation time: "+d1+"<br>");
out.println("Last accessed time: "+d2+"<br>");
out.println("</body></html>");
out.close();
}
}
Output
Question 2
Develop a program to display last accessed time of session. And Expire the session with specified time
SessionDemo1.java
Java
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionDemo1 extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Session Time Out Example</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Session Details</h1>");
HttpSession hs=request.getSession(true);
Date d=new Date(hs.getLastAccessedTime());
out.println("Session id: "+hs.getId()+"<br>");
out.println("Last accessed time: "+d+"<br>");
hs.setMaxInactiveInterval(30);
out.println("</body></html>");
out.close();
}
}
Output
