The WFS Client support only 1.1.0.
If you want to give it a try, it should not be too hard to add support
for 2.0.0 since GeotoolKit can already parse gml 3.2.1 and filter 2.0 .

Hi Johann,
Thank you for your explanation.
In deed, the URL in the capabilities response doesn't point at an xsd
file. the URL is replaced by the new one in the get feature response
though.
What about my second question? do you have any idea about the support
of the version 2.0.0 of a WFS?
Thank you :)
Sincerly yours,

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.
