Hi, thanks for the advice about the parameter. I was not aware of this one until now.
I query features on an external WFS Version 2.0.0. In my case, geotools uses org.geotools.gml3.ApplicationSchemaXSD when looking for the location of the schemas to parse the DescribeFeatureTypeResponse. I've added the second line in the addDependencies method here, so that for the namespace http://www.opengis.net/gml/3.2, the /org/geotools/gml3/v3_2/gml.xsd file from gt-xsd-gml3-28.1.jar is used as the schema. public class ApplicationSchemaXSD extends XSD { /** application schema namespace */ private String namespaceURI; /** location of the application schema itself */ private String schemaLocation; public ApplicationSchemaXSD(String namespaceURI, String schemaLocation ) { this.namespaceURI = namespaceURI; this.schemaLocation = schemaLocation; } @Override protected void addDependencies(Set<XSD> dependencies) { dependencies.add(GML.getInstance()); dependencies.add(org.geotools.gml3.v3_2.GML.getInstance()); } Kind regards Susanne Von: "Roar Brænden" <roar.brenden...@gmail.com> An: "Susanne Köhn" <susanne.ko...@data-experts.de> Kopie: geotools-gt2-users@lists.sourceforge.net Datum: 16.06.2023 07:35 Betreff: Re: [Geotools-gt2-users] Problems with requesting Features from a WSF Version 2.0.0 and using a HTTP proxy Hi, That is good to hear. I don't see which ApplicationSchemaXSD you're talking about, or how you can customize it when you're using WFSClient. Some code would be useful. To avoid extensive download of schemas, it's possible to set the parameter: WFSDataStoreFactory:SCHEMA_CACHE_LOCATION. You can see further explanation here.

However, in my case the performance has become worse compared to the WFS 1.1.0 request. I found out that in ApplicationSchemaXSD for http://www.opengis.net/gml/3.2the local schema file org.geotools.gml3.v3_2.gml.xsd is not found. I added org.geotools.gml3.v3_2.GML in the addDependencies method in ApplicationSchemaXSD. Or is there another solution?

In the sense that it also is set at the HTTPClient. I've made a PRin Github that I believe will fix the problem for both of us. Hilsen Roar 2. jun. 2023 kl. 08:45 skrev Susanne Köhn <susanne.ko...@data-experts.de>: Hello, the main problem is that the HTTPURIHandler opens a connection to load the schemas without considering a proxy, even though the information is already present at the HTTPClient set at the WFSClient.

It would be fine if you report this as a bug. Then I will work more on my solution, so that it could be accepted into the code base. Regards, Roar Brænden fre. 26. mai 2023 kl. 10:25 skrev Susanne Köhn < susanne.ko...@data-experts.de>: Hello, I am using geotools Version 28.1. When requesting Features from a WSF Version 2.0.0 and using a HTTP proxy for the requests I get the following Exception. java.lang.ClassCastException: java.util.HashMap cannot be cast to org.opengis.feature.simple.SimpleFeature at org.geotools.data.wfs.internal.parsers.PullParserFeatureReader.parse( PullParserFeatureReader.java:119) at org.geotools.data.wfs.internal.parsers.PullParserFeatureReader.parse( PullParserFeatureReader.java:47) at org.geotools.data.wfs.WFSFeatureReader.<init>( WFSFeatureReader.java:54) at org.geotools.data.wfs.WFSFeatureSource.getReaderInternal( WFSFeatureSource.java:290) at org.geotools.data.store.ContentFeatureSource.getReader( ContentFeatureSource.java:636) at org.geotools.data.store.ContentFeatureCollection.features( ContentFeatureCollection.java:173) at org.geotools.data.store.ContentFeatureCollection.features( ContentFeatureCollection.java:52) The problem is that the ParserHandler wants to load the Schema for the DescribeFeatureType URL directly. This leads to a java.net.SocketTimeoutException, because the used HTTP proxy is ignored. Is there a way to tell the Parserhandler the Proxy Information? Or is there another way to load the Schema for the DescribeFeatureType?
