After setting up JDBCStore, I add a graphic to the GeoServer styles directory using
curl -v -u admin:geoserver -XPUT -H "Content-type: image/png" --data-binary @smileyface.png http://localhost:8080/geoserver/rest/resource/styles/smileyface.png
I then create a new style:
<?xml version="1.0" encoding="ISO-8859-1"?>
<StyledLayerDescriptor version="1.0.0"
xsi:schemaLocation="http://www.opengis.net/sld http://schemas.opengis.net/sld/1.0.0/StyledLayerDescriptor.xsd"
xmlns="http://www.opengis.net/sld" xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NamedLayer>
<Name>icon</Name>
<UserStyle>
<Title>smileyface</Title>
<FeatureTypeStyle>
<Rule>
<Title>smileface</Title>
<PointSymbolizer>
<Graphic>
<ExternalGraphic>
<OnlineResource xlink:type="simple" xlink:href="smileyface.png" />
<Format>image/png</Format>
</ExternalGraphic>
</Graphic>
</PointSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
If I try to render this style on a layer, I just get grey boxes instead of images. Looking through the debugger, I have traced this issue down to GeoServerDataDirectory line: 1201 . Here, we explicitly convert the resource path into a file path, which causes GeoServer to look in the old data directory (instead of the JDBC Resource Store), which does not contain the image.
