Hi,
I'm connecting to a WPS
(http://geoserver.itc.nl:8080/wps/WebProcessingService?Request=GetCapabilities&Service=WPS)
and trying to load a ProcessDescriptionType for each process it contains to
put into a tree. However, for a number of the processes I get an exception
which says "java.lang.RuntimeException: Parsing failed for LiteralData:
java.lang.RuntimeException: Unable to set property: AllowedValues for
eobject: {http://www.opengis.net/wps/1.0.0}LiteralInputType";
Any idea why this would happen? Code and stack trace below, cheers.
CODE:
public void addWebProcessingService(WebProcessingService wps) {
DefaultMutableTreeNode childNode = new
DefaultMutableTreeNode(wps);
System.out.println("inserting node");
treeModel.insertNodeInto(childNode, wpsTop,
wpsTop.getChildCount());
WPSCapabilitiesType capabilities = wps.getCapabilities();
ProcessOfferingsType processOfferings = capabilities
.getProcessOfferings();
EList processes = processOfferings.getProcess();
for (Object p : processes) {
ProcessBriefType process = (ProcessBriefType) p;
System.out.println(process.getIdentifier().getValue());
String processId = process.getIdentifier().getValue();
try {
DescribeProcessRequest descRequest = wps
.createDescribeProcessRequest();
System.out.println(processId);
descRequest.setIdentifier(processId);
// send the request and get the
ProcessDescriptionType bean to
// create a WPSFactory
DescribeProcessResponse descResponse =
wps.issueRequest(descRequest);
ProcessDescriptionsType processDesc =
descResponse.getProcessDesc();
ProcessDescriptionType pdt =
(ProcessDescriptionType)
processDesc.getProcessDescription().get(0);
addProcessToTree(pdt, childNode);
} catch (Exception e) {
e.printStackTrace();
}
}
tree.scrollPathToVisible(new TreePath(childNode.getPath()));
}
