does a context get a new session?

["Shade, Christopher" <Ch...@247media.com>]

I've seen a variety of session problems posted to the list and in the
archives.  But i'm not sure what's happening in my case.  I have an initial
JSP that puts a Long object into the session, then the user hits a hyperlink
to a servlet, which does stuff and forwards to another JSP.  So it's a JSP
to Servlet to JSP kind of model.  Is it possible that this movement across
contexts (from the /servlet context to the context i defined in the
server.xml for my JSPs) is affecting the session?  
Because when I go to the /servlet context, it creates a new session, so the
Long object isn't there.  But if I just go between JSPs (that are all in the
same directory) the session retains its state.  And the session retains its
state when I go from the servlet to a JSP using
getServletContext().getRequestDispatcher().forward().
I see this code in the InvokerServlet.init() but I don't understand if this
means the invoker gets a new context and session when it invokes a servlet.
 
    public void init() throws ServletException {
 ServletContextFacade facade =
     (ServletContextFacade)getServletContext();
        context = facade.getRealContext();
    }

Totally at a loss, and thanks for any advice,
...Christopher

I bet that if you examine the cookie being written,it is restricted to
the
path the JSP pages are on.
