Hello,
I have three servlets one being called from within another.Im creating a http session in first servlet and setting some attributes for it. I want to getthose attributes in second and thirdservlets. How can i do that? Please suggest a way and give appropriate syntax.
Thanks in advance.

If two servlets are in the same webapp, they share the same session context, and the session is the same for both servlets. Of course, remember that a session is tight to a particular user.
Object value = request.getSession().getAttribute("nameOfTheAttributeUsedInTheFirstServlet");
