session timeout

[Assefa Yewondwossen <as...@dmsolutions.ca>]

Hi There,

I would like to be able to track a session's time out (in a servlet). In

fact all I want to do is to be able to make some clean up (tmp files)
when a session expires.
Are there any examples available that could help me do this ?

Thanks,

I think there is a simpler way...

You can have an class implementing the
javax.servlet.http.HttpSessionBindingListener. Instantiate an object in
each session (the easiest in to set it as a session-scope bean).

when it will receive the valueUnbound message, the session is being
removed from the server. As it is not a destructor, you can do whatever
you want with it.

Attach your own object to the HttpSession, and put a destructor on it - use this
to detect the session has finished. Don't rely on doing complex stuff like I/O
in a destructor, instead pass the list of files to delete into a queue handled
by a background thread.
