java - Session management in the gwt -

i working on gwt-ext application. in application managed client side session. write below code:

to manage session: import com.google.gwt.user.client.timer;

public class clienttimers {      private static final timer session_may_have_expired_timer = new timer() {          @override         public void run() {             // warn user, session may have expired.             // show login dialog, etc...         }     };      public static void renewsessiontimer() {          // first cancel previous timer         session_may_have_expired_timer.cancel();          // schedule again in 5 minutes (maybe make configurable?)         // actually, let's subtract 10 seconds that, because our timer         // won't synchronized server's timer.         session_may_have_expired_timer.schedule(5 * 60 * 1000 - 10000);     } } 

to user activity:

    ext.get("pagepanel").addlistener("click", new eventcallback() {         @override         public void execute(eventobject e) {             //messagebox.alert("on mouse click");     });      ext.get("pagepanel").addlistener("keydown", new eventcallback() {          @override         public void execute(eventobject e) { //             //messagebox.alert("on key press click");         }     }); 

this code working fine issues : code log out automatically time out occurs.for code want on click or key down should logout. case this:if user logged in , time log out 5 min.user don't activity on screen right per above code log out automatically 5 min complete.

now requirement if user logged in , doesn't thing 5 mins.it should not logged out automatically.instead of logging out on completion of 5 min,if user click or key down on 6 min should log out process.

basically log out process timer exceed specified time should done on user activity, not automatically.

in timer, increment variable each second. , when user click on button after 5 minutes or on 6th minute check counter variable , if variable greater 6 can use window.location.reload(); logout or reload().
