I have a further question on this. When I get the list of layers from the
server, it’s a list of useless layer names such as “layer-234”, rather than a
human readable (and informative) title. The title is buried in the
WFSCapabilities object and I cannot see any way to get them out.
Is there a way?
(Since I can get the titles if I put the URL into QGIS, I am assuming that the
server is not necessarily misconfigured).
Thanx
Gaby

Subject: Re: [Geotools-gt2-users] How do I get a list of available layers for a
WFS service
Sorry for not replying before, I'm not sure I saw that email.
Anyway, first construct a WFSDataStore
Map<String, Object> params = new HashMap<>();
params.put(WFSDataStoreFactory.URL.key, baseURL);
if (auth) {
params.put(WFSDataStoreFactory.USERNAME.key, user);
params.put(WFSDataStoreFactory.PASSWORD.key, passwd);
}
// params.put(WFSDataStoreFactory.WFS_STRATEGY.key, "mapserver");
datastore = DataStoreFinder.getDataStore(params);
Then simply ask for the typeNames
String[] names = datastore.getTypeNames();
and then for any name you can grab a featureSource
SimpleFeatureSource source = datastore.getFeatureSource(name);
and features:
SimpleFeatureCollection features = source.getFeatures(query);
Hope that helps
Ian

Hi all, I am sending this again as I did not get any replies before Xmas.
I am trying to implement a WFS service client in our app, but I can’t figure
out how to get a list of available layers from the initial getCapabilities
request.
Something akin to what one can do for WMS:
WebMapServer wms = null;
try {
wms = new WebMapServer(url);
WMSCapabilities capabilities = wms.getCapabilities();
Layer[] layers = WMSUtils.getNamedLayers(capabilities);
if (layers == null || layers.length == 0) {
return "the server does not provide any layers.";
}
} catch (Exception e) {}
