Parsing error on creating WPS factory at DecribeProcessRequest
--------------------------------------------------------------
Key: GEOT-2727
URL: http://jira.codehaus.org/browse/GEOT-2727
Project: GeoTools
Issue Type: Bug
Components: new modules
Affects Versions: 2.6-M2
Reporter: Matthias Lendholt
my first mail to geotools-developer
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:

Since the method works fine (!) for other processes offered by the same WPS
something inside this special process description must be wrong (or wrong in
the parsing code).
I'll attach the describeProcessResponse to this bug report.
