[Geoserver-users] WPS chaining problem

[m.saber]

 

Hi 

I am using geoserver WPS to chain sample processes of
geoserver, 

but I can't access data from wfs or wcs in a wps process,


when executing a request it says only _LOADING............._ 

My
request is something like below (by WPS request builder)

<?xml
version="1.0" encoding="UTF-8"?>
<wps:Execute version="1.0.0"
service="WPS" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns="http://www.opengis.net/wps/1.0.0";
xmlns:wfs="http://www.opengis.net/wfs";
xmlns:wps="http://www.opengis.net/wps/1.0.0";
xmlns:ows="http://www.opengis.net/ows/1.1";
xmlns:gml="http://www.opengis.net/gml";
xmlns:ogc="http://www.opengis.net/ogc";
xmlns:wcs="http://www.opengis.net/wcs/1.1.1";
xmlns:xlink="http://www.w3.org/1999/xlink";
xsi:schemaLocation="http://www.opengis.net/wps/1.0.0
http://schemas.opengis.net/wps/1.0.0/wpsAll.xsd";>

<ows:Identifier>JTS:buffer</ows:Identifier>
 <wps:DataInputs>

<wps:Input>
 <ows:Identifier>geom</ows:Identifier>
 <wps:Reference
xlink:href="http://localhost:8080/geoserver/sf/ows?service=WFS&amp;version=1.0.0&amp;request=GetFeature&amp;typeName=sf:roads&amp;maxFeatures=50&amp;outputFormat=text/xml;%20subtype=gml/3.1.1";
method="GET"/>
 </wps:Input>
 <wps:Input>

<ows:Identifier>distance</ows:Identifier>
 <wps:Data>

<wps:LiteralData>10</wps:LiteralData>
 </wps:Data>
 </wps:Input>

</wps:DataInputs>
 <wps:ResponseForm>
 <wps:RawDataOutput
mimeType="text/xml; subtype=gml/3.1.1">

<ows:Identifier>result</ows:Identifier>
 </wps:RawDataOutput>

</wps:ResponseForm>
