The method logout() is undefined for the type HttpSession

[Javed Ansari]

I am trying to invalidate all the sessions by calling HttpSession.logout() in doPost(). I can see this API in a famous servlet book (Coreservlet and Javaserver pages by MartyHall) but in Eclipse it is not able to find out even with the latest JDK 1.7.

There is no such method in HttpSession

the login() and logout() method is the servlet 3.0 specification , not the jdk 1.7 specification , and this is not in Httpession , this is ih HttpServletRequest . when we call to the logout() method the session attribute are still in session scope , the session is not invalidate if you want to invalidate session , call to the session invalidate() method.
