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!

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>

Thanks a lot. I wasn't able to access images in any other way. – Labyrinthodont 5/7, 2016 at 18:18

Nice answer, but you need to change the 8081 to 8080 assuming the geoserver instance is working on port 8080
