Hello,
I had a look to the WFS service url.
The GeotoolKit client first reads the getCapabilities then tries to
rebuild the feature types from the different DescribeFeatureType
requests. The OGC moved the XSD schema locations a few years ago from
http://schemas.opengeospatial.net to http://schemas.opengis.net, but the
the WFS service on your url still refer to the old urls.
For example :
Old URL : http://schemas.opengeospatial.net/gml/3.1.1/base/gml.xsd
New URL : http://schemas.opengis.net/gml/3.1.1/base/gml.xsd
As a result the old url is redirected to http://schemas.opengis.net
which is not point to a xsd file.
And it causes a jaxb unmarshalling exception.
