Hi,
while letting geotools parse a WFS response from an oracle-based geoserver WFS (1.5.3) it seems I hit http://jira.codehaus.org/browse/GEOS-634. So i thought I'd give some input (and ask for a workaround).
WARNUNG: java.io.IOException: org.xml.sax.SAXException: Could not find element handler for http://www.opengis.net/gml : DZ_RESULTS_POLYGONS as a child of FeatureAssociationType.

DZ_RESULTS_POLYGONS is my FeatureType. The response looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<wfs:FeatureCollection

</gml:Polygon>
</gml:GEOM>
</gml:DZ_RESULTS_POLYGONS>

</wfs:FeatureCollection>
(Slightely edited for readability's sake.)
It seems the prefixes are wrong
<gml:DZ_RESULTS_POLYGONS fid="DZ_RESULTS_POLYGONS.23">
should read
<geb:DZ_RESULTS_POLYGONS fid="DZ_RESULTS_POLYGONS.23">
where 'geb' is my namespace prefix. The same goes for the properties.
Ok, now to the workaround. Does anyone know how to parse a GML string using geotools or have a snippet for doing that? (Perhaps I should ask on their list 
Anyway, the WMS looks fine and is displaying the poly OK.
Cheers,
Ugo
