Hi everyone,
I have some issues with the WFS-NG extension of Geotools 14.3.
I am using the code below to get a data store from a distant server :
String getCapabilities = "
http://ids.craig.fr/wxs/public/wfs?request=getcapabilities&version=2.0.0";;
*Map* connectionParameters = *new* *HashMap*();
*connectionParameters**.put(*
*"WFSDataStoreFactory:GET_CAPABILITIES_URL"**, **getCapabilities** )*;
*connectionParameters**.put(*
*"WFSDataStoreFactory:WFS_STRATEGY"**, **"geoserver"**)*;
// Step 2 - connection
DataStore data = DataStoreFinder.*getDataStore*(
connectionParameters );
// Step 3 - *discouvery*
String typeNames[] = data.getTypeNames();
String typeName = typeNames[0];
SimpleFeatureType *schema* = data.getSchema( typeName );
// Step 4 - target
SimpleFeatureSource source = data.getFeatureSource(typeName);
// Step 5 - query
Query query = *new* Query();
CoordinateReferenceSystem crs=source.getInfo().getCRS();
query.setCoordinateSystem(crs);
query.setMaxFeatures(100);
SimpleFeatureCollection fc = source.getFeatures(query);
SimpleFeatureIterator fiterator=fc.features();
*while*(fiterator.hasNext()){
SimpleFeature sf = fiterator.next();
addFeature(sf,crs);
System.*out*.println(sf.getName());
}
The execution of this code raises the following error:
Exception in thread "main" *java.lang.ClassCastException*:
net.opengis.wfs20.impl.WFSCapabilitiesTypeImpl cannot be cast to
net.opengis.wfs.WFSCapabilitiesType
at
org.geotools.data.wfs.internal.v1_x.StrictWFS_1_x_Strategy.setCapabilities(
*StrictWFS_1_x_Strategy.java:411*)
at org.geotools.data.wfs.internal.WFSClient.<init>(
*WFSClient.java:71*)
at org.geotools.data.wfs.internal.WFSClient.<init>(

at org.geotools.data.wfs.WFSDataStoreFactory.createDataStore(
*WFSDataStoreFactory.java:70*)
at org.geotools.data.DataAccessFinder.getDataStore(
*DataAccessFinder.java:130*)
I don’t understand why the method
org.geotools.data.wfs.internal.v1_x.StrictWFS_1_x_Strategy.setCapabilities
is called instead of
org.geotools.data.wfs.internal.v2_0.StrictWFS_2_0_Strategy.setCapabilities !
Is there a missing parameter in my configuration which I need to add to
force the use of v2_0.StrictWFS_2_0_Strategy class?
I would appreciate any help with that,
Best regards
