[mapserver-users] MapServer, WFS and Oracle

Bart, Jukka,

The shoes taste wonderful. The request comes from OpenLayers, and I can't find how to change it to WFS 1.1, but that'll be another Google search, soon. Right now I thought it'd be smart to see if I at least can get *some* results, manually. This however also fails.

My current request
mapserv.exe?map=address.map&typename=address&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A28992&BBOX=125474.000000,381967.999850,206652.000100,470382.335300

The coordinates come from a previous request (gml:boundedBy) and should definatly contain some points. An 
select count(id) from address where x > 125474 and y > 206652 and x < 381967 and y < 470382
returns 24002 rows (the geo object is also saved as plain X/Y).

For completeness, here's my current MAP file:

MAP
	NAME Test
	STATUS ON
	UNITS meters
	FONTSET "fontset.txt" 
	
	OUTPUTFORMAT
		NAME aggpng24
		DRIVER AGG/PNG
		TRANSPARENT ON
		IMAGEMODE RGBA
		MIMETYPE "image/png"
		EXTENSION "png"
	END
	
    WEB
      METADATA
        "wms_title" "Test"
        "wfs_title" "Test"
        "wms_srs" "EPSG:28992 "
        "wfs_srs" "EPSG:28992 "
        "wms_onlineresource" "<url>"
        "wfs_onlineresource" "<url>"
      END # METADATA
    END #web
	SYMBOLSET "symbols_mapinfo2.sym"
	PROJECTION
		"init=epsg:28992"
	END
	LAYER
		NAME address
		TYPE point
		CONNECTIONTYPE oraclespatial
		DATA "GEOLOC FROM ADDRESS USING SRID 90112 VERSION 10g"
		CONNECTION "x/y/z"
		DUMP TRUE
		PROCESSING "CLOSE_CONNECTION=DEFER"
		CLASS
			SYMBOL "circle"
			OUTLINECOLOR 255 0 0
			SIZE 6
			NAME "address"
		END
		PROJECTION
			"init=epsg:28992"
		END
		METADATA
			"wfs_title" "address"
			"wfs_srs" "EPSG:28992"
			"wms_title" "address"
			"wms_srs" "EPSG:28992"
			"gml_featureid" "ZIPCODE"
			"gml_include_items" "ZIPCODE"
		END
	END
  
END # Map File

As you can see, I use the Dutch projection system everywhere. Yet the request only returns:
<?xml version='1.0' encoding="ISO-8859-1" ?>
<wfs:FeatureCollection
   xmlns:ms="http://mapserver.gis.umn.edu/mapserver"
   xmlns:wfs="http://www.opengis.net/wfs"

      <gml:boundedBy>
      	<gml:Box srsName="EPSG:28992">
      		<gml:coordinates>125474.000000,381967.999850 206652.000100,470382.335300</gml:coordinates>
      	</gml:Box>
      </gml:boundedBy>
</wfs:FeatureCollection>

Any more help would be greatly appreciated.

Jelmer
