Where is the real HttpSession class?

I want to know how to implement the HttpSession. When I send a request to the tomcat, it make a HttpSession Instance. I read the javax.servlet.http.HttpSession, it's just a interface, I want know the detail about the implementation of the Session. I want know where can I found the source code from the tomcat src?
