****************************************************************
WebAppNamedDispatcher is unable to dispatch to a jsp
that is defined in the web.xml as a jsp mapped
servlet.  This Servlet 2.2 requirement was not implemented
in the current release of the product.
Problem conclusion
To meet the Servlet 2.2 requirement for jsp mapped servlets,
changed behavior of WebAppNamedDispatcher to match that
of the more common WebAppRequestDispatcher.
Temporary fix
