Hello geotools community,
I think I discovered a bug in the wfs implementation of geotools. This method call fails with the following error: org.geotools.data.wfs.WFSFeatureSource#getReader() java.lang.RuntimeException: java.io.IOException: Server returned HTTP response code: 400 for URL: http://server/path/wfs?REQUEST=DescribeFeatureType&VERSION=2.0.0&SERVICE=WFS This happens only with certain WFS-Servers. We tracked down the problem to this POST-Request, that is generated from geotools: Works not: curl -X POST -i 'http://server/path/wfs?REQUEST=DescribeFeatureType&VERSION=2.0.0&SERVICE=WFS' --data '<?xml version="1.0" encoding="UTF-8"?><wfs:DescribeFeatureType xmlns:ave="http://repository.gdi-de.org/schemas/adv/produkt/alkis-vereinfacht/2.0"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:fes="http://www.opengis.net/fes/2.0"; xmlns:wfs="http://www.opengis.net/wfs/2.0"; xmlns:gml="http://www.opengis.net/gml/3.2"; xmlns:ows="http://www.opengis.net/ows/1.1"; xmlns:xlink="http://www.w3.org/1999/xlink"; handle="GeoTools 18.0(3f5dbf634c4a6b24476643cc7cf7d2b22747fcf5) WFS 2.0.0 DataStore @LDBV-M-W0378#1" outputFormat="application/gml+xml; version=3.2" service="WFS" version="2.0.0"> <wfs:TypeName>ave:Flurstueck</wfs:TypeName> </wfs:DescribeFeatureType>' Works: curl -X POST -i 'http://server/path/wfs' --data '<?xml version="1.0" encoding="UTF-8"?><wfs:DescribeFeatureType xmlns:ave="http://repository.gdi-de.org/schemas/adv/produkt/alkis-vereinfacht/2.0"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:fes="http://www.opengis.net/fes/2.0"; xmlns:wfs="http://www.opengis.net/wfs/2.0"; xmlns:gml="http://www.opengis.net/gml/3.2"; xmlns:ows="http://www.opengis.net/ows/1.1"; xmlns:xlink="http://www.w3.org/1999/xlink"; handle="GeoTools 18.0(3f5dbf634c4a6b24476643cc7cf7d2b22747fcf5) WFS 2.0.0 DataStore @LDBV-M-W0378#1" outputFormat="application/gml+xml; version=3.2" service="WFS" version="2.0.0"> <wfs:TypeName>ave:Flurstueck</wfs:TypeName> </wfs:DescribeFeatureType>' The "works not" Request is the one produced by geotools. This happens also with the actual release of geotools. The "works" Request is a OGC conform Request. I tracked down the class, that makes the problem. It is the class org.geotools.data.wfs.internal.WFSRequest in the unsupported module gt-wfs-ng. The problem lies in the construktor, where it says: setProperty(SERVICE,"WFS"); setProperty(VERSION, strategy.getVersion()); setProperty(REQUEST, operation.getName()); This properties should only be set, if this.doPost is false, because otherwise the method getFinalURL() delivers a URL with Key-Value-Pairs, even if it is a POST-Request. And this causes this problem with certain WFS-Servers. What do you think about this? And could you be able to fix this bug?
