AW: session listener

[Lauer, Oliver]

Hi, 

you can create an object that implements HttpSessionBindingListener and
store this object in your current session. This object will then be informed
when the session gets bound and unbound.

Betreff: session listener


Hello,

I'd like to add a listener to a session (there's no method for this in
HttpSession class).
I read that I have to configure the web.xml file but I don't know how

Does anyone can help me?

thanks

Oliver's solution works for both Servlet 2.2 (Tomcat 3.x) and Servlet 2.3
(Tomcat 4.x).  If you are using Tomcat 4, however, you do have an
additional option -- you can register application event listeners in the
web.xml file that are notified of interesting events (such as session
creation and deletion, or changes to session attributes).  The /examples
webapp has some listener elements to show you how they are registered.
Look in the API Javadocs for the following APIs:
  javax.servlet.ServletContextListener
  javax.servlet.ServletContextAttributeListener
  javax.servlet.http.HttpSessionListener
  javax.servlet.http.HttpSessionActivationListener
  javax.servlet.http.HttpSessionAttributeListener
for the interfaces you must implement.  The functionality is defined in
the Servlet 2.3 specification, which you can download at:

  http://java.sun.com/products/servlet/download.html
