[ajug-members] JSF question - Additional info

[David Chandler]

JSF's externalContext is a wrapper for either the ServletContext or
PortletContext in which JSF runs so that your beans do not have to
know in which of these environments they are running. In your case,
the ExternalContext is simply wrapping the ServletContext and passing
through the requestURL as it arrived at the servlet. It appears that
the JSP pageContext object incorrectly assumes that the requestURL is
for a JSP page, or perhaps this is an artifact of the way in which JSF
calls the JSP. If you want the URL as it was requested of the servlet,
then getExternalContext() is in fact correct.

Hope that helps,
