I'm trying to read data from an external WFS (always GeoServer

Hum... you are not trying to hit the same GeoServer that is hosting
the WPS right?
Because that will most likely result in a deadlock of the request
Ooops!
Anway, even accessing the WFS on another GeoServer I can't get any
real result, see the XML snippet below.
Thanks & Regards,
