I am trying to address a WPS that is running on a known machine to retrieve some isochrones. Below are excerpts from the relevant parts of the WSDL of said server:
Here are the capabilities as retrieved from the server:
xxx_isochrones XXX Isochrones This process calculates isochrones. Process xxx_isochrones successfully calculated isochrones_png Isochrones PNG PNG showing segments of isochrones for 5, 10 and 20 minutes of traveltime for the chosen means of transport. It reassembles the given bounding box isochrones_gml Isochrones GML GML vector data consisting of segments of isochrones for 5, 10 and 20 minutes of traveltime for the chosen means of transport.
To address the service I am doing the following (error and exception handling removed to increase readability):
// The WeProcessingServiceManager manages a map of already instantiated services, nothing fancy.WebProcessingService wps = WebProcessingServiceManager.getServiceFor(new URL("ourServerURL"));ExecuteProcessRequest request = wps.createExecuteProcessRequest();request.setIdentifier("xxx_isochrones");request.addInput("network_id", Arrays.asList(wps.createLiteralInputValue("bicycles")));request.addInput("x_coord", Arrays.asList(wps.createLiteralInputValue("1234567")));request.addInput("y_coord", Arrays.asList(wps.createLiteralInputValue("1234567")));ResponseDocumentType doc = wps.createResponseDocumentType(false, true, true, "isochrones_pngResult");DocumentOutputDefinitionType odt = (DocumentOutputDefinitionType) doc.getOutput().get(0);odt.setMimeType("image/png");odt.setAsReference(true);ResponseFormType responseForm = wps.createResponseForm(doc, null);request.setResponseForm(responseForm);ExecuteProcessResponse response = wps.issueRequest(request);Unfortunately it seems that I cannot extract the desired result. I am not sure why it isn't working. I followed a very basic tutorial who doesn't explain much. I also find the documentation lacking.
Would anyone have an idea how to extract the desired result, that is, the PNG or at least the URL of the png? Thank you!
