style - Geoserver SLD external graphic path

    

     
       
                    xlink:type="simple"
           xlink:href="glass.png" />
         image/png

I want to use external graphics on my layers. I styled with geoserver admin panel. But external graphics are not working. I put my image into /var/www/geoserver/data/styles folder.

I tried some href options but not worked.

• xlink:href="glass.png"


• xlink:href="file:///glass.png"


• xlink:href="/var/www/geoserver/glass.png"

I think another issue.
