The API of the the HttpSessionAttributeListener interface says:

"Interface for receiving notification events about HttpSession attribute changes.
In order to receive these notification events, the implementation class must be either declared in the deployment descriptor of the web application, annotated with WebListener, or registered via one of the addListener methods defined on ServletContext."

So, my question is why ServletContext.addListener is not in the explanation of the answer?

Thank you
