Hi,

- Read the documentation 
http://docs.geoserver.org/stable/en/user/styling/sld-extensions/pointsymbols.html.

- Open the shipped style “burg.sld” from data_dir/styles. It shows how image 
“burg.svg” is used as external graphics
<ExternalGraphic>
<OnlineResource xlink:type="simple" xlink:href="burg02.svg" />
<Format>image/svg+xml</Format>
</ExternalGraphic>

- Place your symbol “cluster.png” into data_dir/styles and edit the “burg.sld” 
file to have
<ExternalGraphic>
<OnlineResource xlink:type="simple" xlink:href="place.png" />
<Format>image/png</Format>
</ExternalGraphic>

- Test it. Works for me, though I tested with image “symbol.jpg” and format 
“image/jpeg”. Perhaps you have just spent 3 days for neglecting what the manual 
page tells: “If the path of the symbol file is relative, the file is looked for 
under $GEOSERVER_DATA_DIR/styles”?

Hi,

I am a JAVA programmer, we are using Geoserver for our system mapping.

What I am asking about, that I need to insert resource link icons, relative 
folder on our servers, and when tried to update the Styles for layers it gives 
me an error.

The XML code is: <se:OnlineResource xlink:type="simple" 
xlink:href="icons/cluster.png"/>

And the Error is: Parsing failed for ExternalGraphic: 
java.lang.IllegalArgumentException: URI is not absolute

If please could help or guide me to another way as spent three days trying to 
figure this out.
