Difficulty using session object in JSP

I am trying to pass a value from one jsp page to another.

For simplicity in my example the pages are pg1.jsp and pg2.jsp

In pg1.jsp I do as follows.

HttpSessionContext sc=request.getSession().getSessionContext();

request.setAttribute("name", "clive");

String pg2 ="pg2.jsp";

RequestDispatcher pg2Dispatcher = request.getRequestDispatcher(pg2);

            try {
                pg2Dispatcher .include(request, response);
            } catch (Exception exception) {
                out.println("Error: " + exception);

            }

on pg2.jsp 

<%      
   String country = request.getParameter("country"); 
%>
<b> <%=country%>
<%  

This displays "null" on the generated html

If I try to use session instead.

On pg1.jsp 

       try {
                session.include(request, response);
            } catch (Exception exception) {
                out.println("Error: " + exception);
       }

An error occurred at line: 26 in the jsp file:pg2.jsp
session cannot be resolved
23: 
24: if (desktopDispatcher != null){ */
25:        try {
26:                 session.include(request, response);
27:             } catch (Exception exception) {
28:                 out.println("Error: " + exception);
29:        }

I thought that session was automatically available in jsp.

My question is, how can I use Session session, or HTTPSession sesssion inside CQ to pass a variable from one jsp to another?
