I am storing userid and his sessionid into a table in db as and when he logs in to the application.
And I am deleting the entries in sessiondestroyed() method of Sessiontimeoutnotifier.
if we dont do proper logout(closing all windows of application) by the time sessiondestroyed() is called previous sessionid is changed some how, hence that entry from the table is not deleted.
Please any one help me to tackle this issue.
