Answer / anket dhulekar

Use listeners. Since you want to to know how many users have
logged in, so the login info would be stored in a session.
You can create a filter by extending HttpSessionListener,
and update a static variable when the session is created.

The value of this variable will store the number of users
currently logged on.

HttpSessionListener is Listener whenever session is created.

import javax.servlet.http.HttpSessionListener;
import javax.servlet.http.HttpSessionEvent;

public class SessionCounter implements HttpSessionListener {

private static int activeSessions = 0;

public void sessionCreated(HttpSessionEvent se) {
activeSessions++;
}

public void sessionDestroyed(HttpSessionEvent se) {
if(activeSessions > 0)
activeSessions--;
