I need to execute a procedure when a session closes. Is this possible? How
it is made?

Make a class that is a HttpSessionBindingListener - attach an
object of this class to the session. When the session is destroyed
your object will get a call to the valueUnbound method.

I assume by "close" you mean
 - session times out
 - session gets explicitly invalidated by calling .invalidate()
This can be trapped by attaching an object which is a 
javax.servlet.http.HttpSessionBindingListener to the session. 

This object gets call backs when it is bound and unbound from 
a session. When a session "closes" all associated objects get 
unbound.

this is the clean way of doing it.
you could also add some object to the session,
and do whatever you want in the finalizer.

Dirty, but works.

The problems there are that
1) you don't have any guarantee as to when the finalizer will run.
2) if there is another reference to that object hanging around,
   it will never run.

You can put an object that implements HttpSessionBindingListener in the
session. Whenever session.invalidate() is called, it unbinds all objects
bound, so that object receives an HttpSessionBindingEvent and can notify you
the session was closed.

Take a look at the javax.servlet.http.HttpSessionBindingListener interface
and see if that does what your looking for.
