HttpSessionbindingListener

[Henry <he...@cafelab.com>]

Hi FRIENDS:

while I use JSP building my AP , where can I implement this interface? should I implement it just in the page/servlet which
I create session? or I have to implement it all my pages?

Sessions are created automatically by the container, which handles all the
implementation details. An HttpSession is an interface; the container
determines the session's true runtime type. 

Test it on your container:
<%= session.getClass() %>

valueBound/Unbound call back to the object that implements this interface,
telling it that it was added/removed to the session.

Henry,

HttpSessionBindingListener enables you to be notified when an object is
bound into a session, or when the object is removed from the session (either
progammatically, or when the session itself is invalidated or expired).

If you'd like an object stored in the session to be notified in this way, it
must implement the HttpSessionBindingListener interface.

The interface doesn't have any direct relevance to servlets and JSPs, unless
you have some specific session management requirements. You certainly don't
need it to use sessions in the normal way - just use the 'session' object in
JSP, and HttpServletRequest.getSession() in servlets.

HTH,

Dan.
