Re: [Geoserver-users] Create a custom async WPS process

Thu, 20 Dec 2018 05:22:22 -0800 

Hi Spirifer,
I've tried the method you mentioned like the following:

@DescribeProcess(title = "Test", description = ".")
public class Test implements GeoServerProcess {

@DescribeResult(name = "result", description = "output result")
public String execute(@DescribeParameter(name = "name", description = "name to 
return") String name,
        ProgressListener listen) throws InterruptedException {
                listen.progress(10f);
                Thread.sleep(10 * 1000);
                listen.progress(30f);
                Thread.sleep(10 * 1000);
                listen.progress(60f);
                Thread.sleep(10 * 1000);
                listen.progress(100f);
                return "Hello, " + name;
        }
}


And when I try to test it using following Post request:

<?xml version="1.0" encoding="UTF-8"?>
<wps:Execute version="1.0.0" service="WPS" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

        <wps:LiteralData>koko</wps:LiteralData>
      </wps:Data>
    </wps:Input>
  </wps:DataInputs>
  <wps:ResponseForm>
    <wps:ResponseDocument storeExecuteResponse="true" status="true">
        <wps:Output mimeType="application/json">
        <ows:Identifier>result</ows:Identifier>
        </wps:Output>
    </wps:ResponseDocument>
  </wps:ResponseForm>
</wps:Execute>


It gives the following response:

<?xml version="1.0" encoding="UTF-8"?>
<wps:ExecuteResponse xmlns:xs="http://www.w3.org/2001/XMLSchema"; 
xmlns:ows="http://www.opengis.net/ows/1.1";

serviceInstance="http://localhost:6256/geoserver/ows?"; 
statusLocation="http://localhost:6256/geoserver/ows?service=WPS&amp;version=1.0.0&amp;request=GetExecutionStatus&amp;executionId=58745f88-16a0-4d4b-ad10-9a5e0f23f172";
 version="1.0.0">
    <wps:Process wps:processVersion="1.0.0">
        <ows:Identifier>
            gs:Test
        </ows:Identifier>
        <ows:Title>
            Test
        </ows:Title>
        <ows:Abstract>
            .
        </ows:Abstract>
    </wps:Process>
    <wps:Status creationTime="2018-12-20T12:57:57.257Z">
        <wps:ProcessAccepted>
            Process accepted.
        </wps:ProcessAccepted>
    </wps:Status>
</wps:ExecuteResponse>


And when I call the following GET request (to monitor the process progress):

http://localhost:8080/geoserver/ows?service=WPS&version=1.0.0&request=GetExecutionStatus&executionId=58745f88-16a0-4d4b-ad10-9a5e0f23f172

It gives the following response:

<wps:ExecuteResponse xml:lang="en" service="WPS" 
serviceInstance="http://localhost:6256/geoserver/ows?"; 
statusLocation="http://localhost:6256/geoserver/ows?service=WPS&version=1.0.0&request=GetExecutionStatus&executionId=58745f88-16a0-4d4b-ad10-9a5e0f23f172";
 version="1.0.0"><wps:Process 
wps:processVersion="1.0.0"><ows:Identifier>gs:Test</ows:Identifier><ows:Title>Test</ows:Title><ows:Abstract>.</ows:Abstract></wps:Process><wps:Status
 
creationTime="2018-12-20T12:57:57.257Z"><wps:ProcessFailed><ows:ExceptionReport 
version="1.1.0"><ows:Exception 
exceptionCode="NoApplicableCode"><ows:ExceptionText>Process failed during 
execution
Parameter arg1 is missing but has min multiplicity &gt; 
0</ows:ExceptionText></ows:Exception></ows:ExceptionReport></wps:ProcessFailed></wps:Status></wps:ExecuteResponse>


It tells that there is a missing parameter!!
What is my problem? how should I call this WPS?

Thanks,
Nanaso
