The prefix used to denote the namespace reserved for and
used by Jetspeed-specific configuration parameters (such as
those passed in via servlet container's config file
(server.xml), or the web app deployment descriptor
(web.xml).
For example, a parameter in the Jetspeed namespace would be
org.apache.jetspeed.loggingRoot.
This is the key used in the jetspeed.properties to access resources
relative to the Web Application root. It might differ from the
Application root, but the normal case is, that the webapp root
and the application root point to the same path.
