[Geoserver-devel] [JIRA] (GEOS-8467) Appschema and Sld for WMS

_Failed_to_Retrieve · December 4, 2017, 4:26pm

Issue Type:	Bug
Affects Versions:	2.8.2
Assignee:	Unassigned
Components:	Application schema

Environment:	Linux Centos 7
Priority:	Medium
Reporter:	Francisco Caldeira

I have a service for the INSPIRE theme Geographical names, created with appschema extension.

It’s working fine for the WFS in the address:

http://inspire.ine.pt/geoserver/gn/wfs?

Not so good with WMS… I’m trying to define a Style to label a field like the INSPIRE directive defines, which goes like this:

<?xml version=“1.0” encoding=“ISO-8859-1”?>

<StyledLayerDescriptor version=“1.0.0”

xsi:schemaLocation=“http://www.opengis.net/sld StyledLayerDescriptor.xsd”

xmlns=“http://www.opengis.net/sld”

xmlns:ogc=“http://www.opengis.net/ogc”

xmlns:xlink=“http://www.w3.org/1999/xlink”

xmlns:gn=“http://inspire.ec.europa.eu/schemas/gn/4.0”

xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”>

<!-- a Named Layer is the basic building block of an SLD document –>

<Name>GN Geographical Names</Name>

<!-- Styles can have names, titles and abstracts –>

<Title>GN.NamedPlaced</Title>

<Abstract>Label place name</Abstract>

<Rule>

<Name>GN.NamedPlaced.name</Name>

<Title>Label with no outline</Title>

<Abstract>A arial 10pt label </Abstract>

<Label>

<ogc:PropertyName>gn:NamedPlace/gn:name/gn:GeographicalName/gn:spelling/gn:SpellingOfName/gn:text/@xlink:href</ogc:PropertyName>

</Label>

<Font>

<CssParameter name=“font-family”>Arial</CssParameter>

</Font>

</AnchorPoint>

</Displacement>

</PointPlacement>

</LabelPlacement>

</TextSymbolizer>

</Rule>

</FeatureTypeStyle>

</UserStyle>

</NamedLayer>

</StyledLayerDescriptor>

The error I Receive is:

The requested Style can not be used with this layer. The style specifies an attribute of gn:NamedPlace/gn:name/gn:GeographicalName/gn:spelling/gn:SpellingOfName/gn:text/@xlink:href and the layer is: gn:NamedPlace

I understand I have to define an xpath, I have read it on the documentation. But I’m not sure if I have done it correctly, tried several variations but none worked out.

This is the link for the WMS

http://inspire.ine.pt/geoserver/gn/wms?service=WMS&version=1.1.0&request=GetMap&layers=gn:NamedPlace&styles=&bbox=-119776.5078125,-301720.375,122336.6484375,278733.625&width=330&height=768&srs=EPSG:3763&format=application/openlayers

My appschema.xml file goes like this. I’ trying to map the field

<targetAttribute>gn:name/gn:GeographicalName/gn:spelling/gn:SpellingOfName/gn:text</targetAttribute>

<?xml version=“1.0” encoding=“UTF-8” standalone=“yes”?>
