Arrow Configuration Error

This URL is configured to be handled by the dispatcher keyed with '#{@key.inspect}',
but there was no dispatcher associated with that key. The instances I know about 
are:

#{@instances.collect {|k,d| "-- #{k.inspect} --\n\n#{d.inspect}"}.join("\n\n")}

	EOF

	return Apache::OK
