Hello Hanane, and welcome!
I'm not familiar myself on the WFS part, since Apache SIS is just
starting to support its first web services (through Hao's work in Google
Summer of Code). But I will try to get a Geotk developer to answer your
question. I may not be able to reach them before Monday however.
Regards,
Martin
