Message:

java.io.FileNotFoundException

This error has occurred for one of these reasons:

You have incorrectly specified the name of a VoiceXML document file in
the path of an appname entry in the default.cff configuration file
and an error has occurred during dtjstart

You have referred to a secondary VoiceXML document from an initial one
using an incorrect filename. In this case dtjstart is successful,
but the error occurs when the secondary document is called with the wrong
filename.

To resolve this problem for a speech browser that runs automatically, stop
the node with dtjstop, edit the filename in appname entry
of the default.cff configuration file, run dtjconf and restart
the node with dtjstart. 

For a speech browser that you started manually with the vxml command,
reissue the command with the correct VoiceXML document filename. This error
can occur for an incorrectly referenced root document or an incorrectly referenced
VoiceXML document. 

For audio files that the system cannot locate, this error occurs if no
text string alternative has been defined in the audio markup element
in a VoiceXML document.
