Hi this is tanu, This is a code for knowing how many times a servlet has been accessed. but after executing this i am getting only 1 as output for many times of execution. I want to store the counter value once and then want to know how many times it(servlet) has been called. How to store that value and where?

package counter;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
//In this example we are going to know how we can make a program on counter which will keep track 
//how many times the servlet has been accessed. 
/**
 * Servlet implementation class SimpleCounter
 */
public class SimpleCounter extends HttpServlet {
    int counter = 0;
    //private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        counter++;
        out.println("At present the value of the counter is:" + counter);
        // TODO Auto-generated method stub
    }

}
