Cannot submit route requests using lat/long to Oracle RouteServer

Question

I have version 10g of Oracle RouteServer running under OAS, and a backend 10g database loaded with some NAVTEQ data. The route server handles ordinary requests with un-geocoded addresses -- most of the time. Whenever I attempt a route request using latitude and longitude, even using the sample requests at http://<myhost>/routeserver/route_requests/lat_long.html, I get the following response:
<RouteServerException>
[RSE-0206: Unexpected output format from Geocoder!!!]
</RouteServerException>.
What does this mean? How can the Oracle-provided sample request fail?

Answer 1

Here's the XML for the original lat/long routing request to the Oracle RouteServer.
<?xml version="1.0" standalone="yes"?>
<route_request id="8"
route_preference="shortest"
road_preference="highway"
return_driving_directions="true"
distance_unit="meter"
time_unit="second"
return_route_geometry="true">
<start_location>
<input_location id="1" longitude="-122.39382" latitude="37.79518" />
</start_location>
<end_location>
<input_location id="2" longitude="-122.4054826" latitude="37.7423566" />
</end_location>
</route_request>
When I run a reverse geocoding query using the input location coordinates in the underlying database with
SELECT SDO_GCDR.REVERSE_GEOCODE('ODFUSER',
SDO_GEOMETRY(2001, 8307,
SDO_POINT_TYPE(-122.39382, 37.79518, NULL), NULL, NULL),
'US') FROM DUAL
and
SELECT SDO_GCDR.REVERSE_GEOCODE('ODFUSER',
SDO_GEOMETRY(2001, 8307,
SDO_POINT_TYPE(-122.4054826, 37.7423566, NULL), NULL, NULL),
'US') FROM DUAL
I get
SDO_GEO_ADDR(0, SDO_KEYWORDARRAY(), NULL, 'THE EMBARCADERO', NULL, NULL, 'SAN FRANCISCO BAY AREA', 'SAN FRANCISCO', 'CA', 'US', '94111', NULL, '94111', NULL, NULL, 'THE EMBARCADERO', NULL, 'F', 'F', NULL, NULL, 'R', 1, 916027581, '', 1, 'DEFAULT', -122.39382, 37.79518, '????1141114??404?')
and
SDO_GEO_ADDR(0, SDO_KEYWORDARRAY(), NULL, 'FLOWER ST', NULL, NULL, 'SAN FRANCISCO', 'SAN FRANCISCO', 'CA', 'US', '94124', NULL, '94124', NULL, '21', 'FLOWER', 'ST', 'F', 'F', NULL, NULL, 'L', .596104898, 199223581, '', 1, 'DEFAULT', -122.40546, 37.7424313, '????4141414??404?')
respectively. I'm fairly novice at reading this, but it appears that the reverse geocoding was successful. That makes it all the more puzzling as to why the routeserver, using the same data source, returns the following (in my browser window - IE7, FF 3.0.12, Chrome 2.0.172.33):
<RouteServerException>
[RSE-0206: Unexpected output format from Geocoder!!!]
</RouteServerException>
By the way, the database version is 10g Enterprise Edition Release 10.2.0.4.0.
