    I tried to implement httpsessionlistener interface but it is not
    destroy method once the user closes the browser window though it is
    properly running the create method. I am using the following code and
    in destroy method it has to display only text but it is not. Please
    send some suggestion.

    public class SessionCounter implements HttpSessionListener {

            private static int activeSessions = 0;
                    static String url="jdbc:odbc:candico";

            /* Session Creation Event */
            public void sessionCreated(HttpSessionEvent se) {

            /* Session Invalidation Event */
            public void sessionDestroyed(HttpSessionEvent se) {


            public static int getActiveSessions() {
                    return activeSessions;
