Dear Toni,
Let me make a correction to my previous email:
The closest I could reach was by getting gray square symbols instead of
images by using this path
<sld:OnlineResource xlink:type="simple" xlink:href="
172.18.0.6/usr/local/tomcat/weabapps/geoserver/data/styles/day.svg"/>
The other ones, I could not get response at all:
<sld:OnlineResource xlink:type="simple"
xlink:href="c3499bb0ae79:/usr/local/tomcat/weabapps/geoserver/data/styles/day.svg"/>
<sld:OnlineResource xlink:type="simple"
xlink:href="geoserver4my_geonode:/usr/local/tomcat/weabapps/geoserver/data/styles/day.svg"/>
Thank you very much for your time
Kind regards
Julierme
