my doubt is Does HttpSession class has the method getServletContext??
Thx

Yes offcourse.
HttpSession class has a getServletContext() through which we acquire the reference to ServletContext object.

take a look at session API, you will see this method.
What's more, I believe if session obj. can't get servletContext, there's no way for Http***Listener to know anything about the context.
