session management

[Michael <to...@meinsenf.at>]

Hi!

I want to create a directory in my file-system for every new session - that's easy!
(there I want to store large files belonging to that session!)

Now I would like to get rid of the directories of older timed-out sessions!!!
.
It would be enough, if every time, when I have to create a new session and a new directory, all session-directories are checked for their valid sessions - and if a directory exists though the session has already timed-out, it will be deleted!

is this possible?

thanks
michi

Look at javax.servlet.http.HttpSessionBindingListener.

Say you have a class MyClass that implements HttpSessionBindingListener.
When you call HttpSession.setAttribute("name", myClass), the valueBound()
method of MyClass gets called. Likewise when the session expires or the
object is explicitly removed from the session, the valueUnbound() method
is called.

So if you put a listener in the session attributes, you will know when
the session dies.
