Hi,
We are having a slight problem when trying to read WFS 1.1 response that is
returned in GML 3.2.1. (GeoTools 2.7-M4)
Currently, we are reading all WFS responses using GeoTools like so:
Parser parser = new Parser(...);
parser.setValidating(false);
parser.setFailOnValidationError(false);
parser.setStrict(false);
FeatureCollection<SimpleFeatureType, SimpleFeature> features =
(FeatureCollection<SimpleFeatureType, SimpleFeature>)
parser.parse(response.getResponseAsInputStream());
but now are getting ClassCastException "java.util.HashMap cannot be cast to
FeatureCollection".
XML response contains multisurface object like this:
<gml:MultiSurface gml:id="XXX.MultiSurface" srsName="EPSG:3067">
<gml:surfaceMember>
<gml:Surface gml:id="XXX.Surface" srsName="EPSG:3067">
<gml:patches>
<gml:PolygonPatch>
<gml:exterior>
<gml:LinearRing>
<gml:posList>xx yy ...</gml:posList>
</gml:LinearRing>
</gml:exterior>
<gml:interior>
<gml:LinearRing>
<gml:posList>xx yy ...</gml:posList>
</gml:LinearRing>
</gml:interior>
</gml:PolygonPatch>
</gml:patches>
</gml:Surface>
</gml:surfaceMember>
</gml:MultiSurface>
Now, is there an easy way to convert HashMap WFS GetFeature result to a
"Layer" that could be render into an image something like this:
String style = "...";
FeatureCollection<SimpleFeatureType, SimpleFeature> features = {magic
conversion from HashMap to FeatureCollection }
MapContext mapContext = buildMapContext();
mapContext.addLayer(features, style);
Cheers.
