Hi Jody,
thanks for your answer. That's a bit ... unfruitful for me. Since we are
using uDig and the included GeoTools library it will get our project
more complex working on GeoTools trunk and putting them both together.
Particulary we are already using the process API for several tasks and
this works fine: both in our client application but also in the deegree3
WPS server. It seems that just GeoTools' wps-client has this bug. I'll
check how I can add the sources to my IDE to debug it out of my
uDig-based application. And then I have to clarify internally if we can
spend some resources to fix this GeoTools functionality or if we have to
switch to another WPS-client. It's not up to me to decide this alone :-)
Thanks again!
Matthias
