Applying SLD file exported from QGIS in GeoServer - why is color not applied?

Question

I was trying to put style of color classification that was created in QGIS. It works in Geoserver but the colors are not shown. It is always single color. I have read that this is often a problem with some versions of QGIS, but I do not know how to solve it. It would be helpful if someone knows what should I change in code.

Answer 1

look closely, and you'll see the problem, hiding in plain sight...

<!--Parser Error: syntax error, unexpected COLUMN_REF, expecting $end - Expression was: Land use 2 = 'Residential buldings'-->

I suspect you'll need to edit the SLD to rename the field name, e.g. "land_use_2". How you do this depends on the format you're importing from (shapefile, csv, postgres etc)

Answer 2

I export the SLD from QGIS 2.2 and I am running Geoserver 2.6. For the export from QGIS to work, I change the se:SvgParameter into sld:CssParameter.

Generally using SDL 1.0 instead of 1.1.0 prove to simplify some of the issues of transferring the symbology form QGIS to Geoserver in my case. But this will depend on the versions of the software you have. Additionally, as @Steven Kay explained there is an issue with that line, so fix this first.

PS: in that case, your code

<se:Name>Yards and parking areas of residential zones</se:Name>
          <se:Description>
            <se:Title>Yards and parking areas of residential zones</se:Title>
          </se:Description>

would look more like ( description tag not in sld 1.0 according to geoserver validator)

   <Name>Yards and parking areas of residential zones</Name>
   <Title>Yards and parking areas of residential zones</Title>
