this is my loging.jsp

this is my listener class

package listeners;

import dao.TicketDetails;
import dao.ZoneDaoImpl;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
import org.omg.PortableServer.REQUEST_PROCESSING_POLICY_ID;

public class MyHttpSessionListener implements HttpSessionListener {

static private int activeSessions;

public static int getActiveSessions() {
        return activeSessions;
    }

public void sessionCreated(HttpSessionEvent se) {
        activeSessions++;
        try {
            getAllData();
        } catch (Exception ex) {
            Logger.getLogger(MyHttpSessionListener.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

public void sessionDestroyed(HttpSessionEvent se) {
        activeSessions--;
    }

private void getAllData() throws Exception {
        ZoneDaoImpl z = new ZoneDaoImpl();
        // z.getConnection();
        ArrayList a = z.geTicketDetails();
        ArrayList b = z.getUserDetails();
        MyAllData.setMydata(a);
        MyAllData.setUserdata(b);

}

when a user loging it doesn't access the listener class?
where is the problem?

What makes you think that anything you do during the login processing (the part that you didn't deem suitable to show us) will trigger the listener?

Please try using complete sentences when posting. What makes you think that a new session is being created?

Getting snippy will not help you get better or faster answers.

You need to think about the assumptions that you are making. Are they really true?

You aren't putting in any effort yourself.

Please answer my questions: What makes you think that the listener is not working? What assumptions are you making to support that claim?

Please use complete sentences. Please think about the problem rather than just expecting someone else to do it for you.
