Hi Toni,
Regarding my previous email, GeoServer at 2.14.2 was causing the problem. I
removed GeoServer at 2.14.2 and installed GeoServer at 2.14.1 and issue is
solved. Find geo.sld bellow working smoothly on GeoServer at 2.14.1 and a
screenshot of tb_brasilia_weather layer. Now, I am doing the same thing in
my GeoNode at 2.8 in a CenTos7 Server installed via Docker and
GeoServer at 2-13-SNAPSHOT in geoserver4my_geonode container.
Using the same geo.sld file, I am having some problem trying to reach the
image files in geoserver4my_geonode container. I tried the settings
bellow without no success.
<sld:OnlineResource xlink:type="simple"
xlink:href="c3499bb0ae79:/usr/local/tomcat/weabapps/geoserver/data/day.svg"/>
<sld:OnlineResource xlink:type="simple"
xlink:href="geoserver4my_geonode:/usr/local/tomcat/weabapps/geoserver/data/day.svg"/>
<sld:OnlineResource xlink:type="simple" xlink:href="172.18.0.6:
/usr/local/tomcat/weabapps/geoserver/data/day.svg"/>
Any suggestion or comment on this issue will be very appreciated.
I appreciated your time and help
Kind regards
Julierme
