Write a Servlet which displays a message and also displays how many times the message has been displayed (how many times the page has been visited).

Write a Servlet which displays a message and also displays how many times the message has been displayed (how many times the page has been visited). 
  
Hint: Create a file which will update the counter each and every time the page is being loaded. 


(Simple Counter Variable is Used Without making use of session , cookies  or database)

---

Step 1: Create VisitCounter.Java using Packages Concepts for servlet which can handle counter variable to keep a track on visits.

package pack4;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class VisitCounter extends HttpServlet
{
private int Count = 0;
public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter(); if(Count > 0)
{
out.println("Wellcome Again ...!");
out.println("<br>Page Visited : " + ++Count+ " Times");
}
else if(Count <= 0)
{
out.println("Wellcome..!!");
out.println("<br>Page Visited : " + ++Count+ " Times");

}
}
}

Step 2: Create WEB.XML file for Mapping Servlet file.

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
<servlet>
      <servlet-name>SimpleVisitCounter</servlet-name>
      <servlet-class>pack4.VisitCounter</servlet-class>
</servlet>  
<servlet-mapping>
        <servlet-name>SimpleVisitCounter</servlet-name>
        <url-pattern>/Visit</url-pattern>
</servlet-mapping>
</web-app>
