One key issue is that sessions are only valid within a particular servlet
context. In the default JSWDK setup (as well as for Tomcat), any URL that
begins "/examples" is in one servlet context, while everything else is in a
different one that handles all URLs that do *not* begin with "/examples".
Therefore, sessions will not cross the boundary between the two.
If your JSP page that is linking to this servlet is in the "/examples" tree,
this is why the session works with the first URL
(/examples/servlet/InstallProServlet) but not the second
(/servlet/InstallProServlet).
