When talking about the session management, one thing that comes to mind is the lifetime of the session. Most of the Web applications, like e-commerce, banking, hotel reservation, and so on, have a predefine lifetime. If you are not active for that time, it will automatically terminate your session and prompt you to log in again. Hence, there is a particular time when a session gets started and another when the session finishes. So whoever writes a session aware service might need to know when a session starts and when it finishes. To facilitate this, Axis2 uses Java reflection and optional interfaces to inform the service implementation class. Actually, there are two ways that a service author is notified when a session starts and finishes, irrespective of the session scope.
