Chris is right of course -- servlets that inherit from GenericServlet provide
a getServletContext() method for you, but the Java class that a JSP page
generates does not subclass this class -- it only implements the Servlet
interface which has getServletConfig().

I guess you can tell how many times I actually embed Java code in my JSP
pages, if I thought that this would work :-).
