Note: The Servlet 2.3 specification also contains the javax.servlet.http.HttpSessionBindingListener and the javax.servlet.http.HttpSessionActivationListener interfaces. These interfaces are implemented by objects that are stored as session attributes and do not require registration of an event listener in web.xml. For more information, see the Javadocs for these interfaces.
