Hi
I’m attempting to submit a GetFeature request to GeoServer (2.1.3) using the POST method. I want to use WFS 1.1.0/gml3 so that I get a “number of features= x” response (WFS 1.0.0 doesn’t return this). I’m using an ‘Intersects’ filter and I’m supplying the vertices of a polygon for the intersect. The POST data is as follows:
var postData =
‘<wfs:GetFeature\n’
-
’ service=“WFS”\n’
-
’ version=“1.1.0”\n’
-
’ outputFormat=“text/xml; subtype=gml/3.1.1”\n’
-
’ maxFeatures=“350”\n’
-
’ xmlns:wfs=“http://www.opengis.net/wfs”\n’
-
’ xmlns:ogc=“http://www.opengis.net/ogc”\n’
-
’ xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”\n’
-
’ xmlns:gml=“http://www.opengis.net/gml/”\n’
-
’ xsi:schemaLocation="http://www.opengis.net/wfs\n’
-
’ <wfs:Query typeName=“ROS:titleExtents” srs=“urn:x-ogc:def:crs:EPSG:27700”>\n’
-
’ <ogc:Filter xmlns:ogc=“http://www.opengis.net/ogc”>\n’
-
’ ogc:Intersects\n’
-
’ ogc:PropertyNamethe_geom</ogc:PropertyName>\n’
-
’ <gml:Polygon srs=“urn:x-ogc:def:crs:EPSG:27700”>\n’
-
’ gml:exterior\n’
-
’ gml:LinearRing\n’
-
’ gml:posList325114.43014706 673592.1753978 325112.1897978 673577.23973604 325124.8851103 673584.70756692 325114.43014706,673592.1753978</gml:posList>\n’
-
’ </gml:LinearRing>\n’
-
’ </gml:exterior>\n’
-
’ </gml:Polygon>\n’
-
’ </ogc:Intersects>\n’
-
’ </ogc:Filter>\n’
-
’ </wfs:Query>\n’
-
‘</wfs:GetFeature>\n’;
var request = new OpenLayers.Request.POST({
url: ‘/ros/geoserver/wfs’,
data: postData,
headers: {
“Content-Type”: “text/xml”
},
callback: function (response) {
// read the response from GeoServer
var format = new OpenLayers.Format.GML.v3({});
// Add features to vector layer
selection_layer.addFeatures(format.read(response.responseText));
alert(response.responseText);
},
failure: function (response) {
alert(“Invalid request”);
}
});
Unfortunately, I’m getting the following response from Geoserver:
<?xml version="1.0" encoding="UTF-8"?>
<ows:ExceptionReport version="1.0.0"
xsi:schemaLocation="http://www.opengis.net/ows http://31.222.143.15:80/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ows="http://www.opengis.net/ows">
<ows:Exception exceptionCode="NoApplicableCode">
<ows:ExceptionText>java.lang.RuntimeException: Parsing failed for Polygon: java.lang.ClassCastException: java.lang.String cannot be cast to com.vividsolutions.jts.geom.LinearRing
Parsing failed for Polygon: java.lang.ClassCastException: java.lang.String cannot be cast to com.vividsolutions.jts.geom.LinearRing
java.lang.String cannot be cast to com.vividsolutions.jts.geom.LinearRing</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>
The query works fine if I revert to WFS 1.0.0, but for some reason I’m getting this parsing error with WFS 1.1.0. I can’t see what I’m doing wrong here – can anyone help out please?
Thanks
