[Geoserver-users] Custom Inputtype for WPS

[vermesser123 <max...@ya...>]

Hello everybody,

I want to use a custom input-type in a wps, so that the client can send a
request like this:

...
<wps:Data>
    <wps:ComplexData>
          <customFormatPPIO>
                   <feature_id>12345</feature_id>
                   <feature_name>house</feature_name>
          </customFormatPPIO>
</wps:ComplexData>
</wps:Data>
...

I declared in the org.geoserver.wps.ppio package a class customFormatPPIO
with the members feature_id and feature_name.

public class customFormatPPIO extends ComplexPPIO
{
private String id;
private String name;

public customFormatPPIO() {
...
}
public void encode(...){...}

public Object decode(...){...}

Also, I registered the class in the ProcessParameterIO:

defauls.add(new customFormatPPIO(...));


I thought, that a incoming request is routed to the decode-function in the
customFormatPPIO.class, however, there is a exception in
AnnotationDriverProcessFactory.class;

org.geotools.process.ProcessException: Could not convert {id=12345,
name=house} to target type org.geoserver.wps.ppio.customFormatPPIO
	at
org.geotools.process.factory.AnnotationDrivenProcessFactory$InvokeMethodProcess.buildProcessArguments(AnnotationDrivenProcessFactory.java:627)
	at
org.geotools.process.factory.AnnotationDrivenProcessFactory$InvokeMethodProcess.execute(AnnotationDrivenProcessFactory.java:501)


Any idea, what to do or how to implement custom input types in a wps?

Thanks


Max Meier
