Implementation of ServletContext, HttpRequest, HttpResponse etc are done by container provider.

When we access ServletContext, its the object of ServlectContext type of implementation which is passed by container to Servlet.

I never tried to find out class in Container which implement these Interfaces provided by Servlet Specs. I would suggest you to browse servlet.jar.

Whether they are internally implemented or they are class files of the implementation........

hi,

For better understanding, remember every servlet have their own servlet context object.

So, when you extend your class with HttpServlet class you explicitly access your servlet "servlet context" object.

So, no need to implement your class to "servletcontext" interface.

Since Tomcat is open-source, you can download the complete Java source code and explore the actual implementation. However this is not necessary - all you need to program for the servlet environment is the servlet specification and the JavaDocs for the API.
