Geoserver SLD styling issue with external graphics and attribute rules

geoserver, icons, image, sld, wms

Solution

I realize this post is old but maybe someone will benefit from my answer.

I didn't succeed in using relative image paths so I turned to using URL paths.

Put image(s) in $GEOSERVER_DATA_DIR/styles and reference it with `http://localhost:8081/geoserver/styles/some_image.png`

For example

<ExternalGraphic>
  <OnlineResource xlink:type="simple" xlink:href="http://localhost:8081/geoserver/styles/some_image.png"/>
  <Format>image/png</Format>
</ExternalGraphic>

Problem

I am creating a SLD for Geoserver wms layer. The SLD validates without error but the icons will not show in the map. I am using attribute based rules to compare strings to have the correct image show for the correct feature. Here is my code and thanks for any help! ``` <?xml version="1.0" encoding="ISO-8859-1"?> <StyledLayerDescriptor version="1.0.0" xsi:schemaLocation="http://www.opengis.net/sld
