Dear list,
I've created a convenience method to create WPSFactory in my project:
public static WPSFactory getWpsFactory(URL wpsUrl, String
processName)throws ServiceException, IOException {
WebProcessingService wps = new WebProcessingService(wpsUrl);
DescribeProcessRequest descRequest = wps.createDescribeProcessRequest();
descRequest.setIdentifier(processName);
DescribeProcessResponse descResponse = wps.issueRequest(descRequest);
ProcessDescriptionsType processDesc = descResponse.getProcessDesc();
ProcessDescriptionType pdt = (ProcessDescriptionType)
processDesc.getProcessDescription().get(0);
return new WPSFactory(pdt, wpsUrl);
}
The code is copied from http://docs.codehaus.org/display/GEOTDOC/WPS+Plugin
Calling this method with a valid url (pointing to a local wps) an a
processName results in row "DescribeProcessResponse descResponse =
wps.issueRequest(descRequest);" in this exception:

I'm using uDig 1.2M6 and the included GeoTools libraries. Any hints
what's wrong? The processName is exactly matching the process identifier
of the GetCapabilites of the WPS.
Thank you,
Matthias
