RE: [Geoserver-devel] getting image from wms results in error

it's strange:

with styles=green i'm now able to get a .png or .jpg of my province-layer but NOT an .svg altough .svg works for the bc_roads-example-layer. my province-layer is served by a postgis-datastore, could this make a difference...?

This could be a style problem. Make sure the style contain FeatureTypeStyle for your FeatureType and that they have approriate symbolisers. This bit me also. Unfortunately SLD does not provide very good generic styling.

So I spent a bit of time investigating, and it looks like the SVG encoder
missed a call to encode polygons. I'm having trouble with my SVG
plug-ins, so I couldn't actually view it, but it now _does_ generate xml
for the lines. I assume your layer is polygons, or else we've got some
other problem... I was able to succesfully use a postgis datasource. It
looks like the class has two ways to encode polygons, if this doesn't work
you may try changing line 561 to say writePolyContent( instead of
writePoly( . So just move this class to
geoserver/src/org/vfny/geoserver/responses/wms/map/ and rebuild geoserver,
and it may fix the problem. Thanks for catching the bug, and let me know
if this fix works.

yes, my province-layer is polygons. with the modified SVGEncoder it works perfect, thanks for fixing that.

for my purpose it would be nice to still have the fid-attribute from the gml-output in the svg-output. i will probably modify SVGEncoder a bit. does the Feature-class expose this attribute?

<jpp:country fid="country.19260">

<path d="..." id="country.19260" />

The SVGEncoder version I have in my computer has the ability of encoding FID
and any other attribute data
as attributes in the resulting SVG elements for each feature. Althoug I was
very inactive in geoserver for the last
2 months, I think I'll be able of commiting it if you need it.

please all of you excuse my ausence, since some of the discused topics were
directly related to my work in geoserver,
it's just that I was (and still I am) trying to reach a dead line were it
was supposed we were 5 developers and actually we're just 3, so I'm very
bussy with my main project.

regards,

Gabriel Roldán.

Cool, sorry I missed it before the release, I should have done more
testing.

for my purpose it would be nice to still have the fid-attribute from
the
gml-output in the svg-output. i will probably modify SVGEncoder a
bit. does
the Feature-class expose this attribute?

Yes, you should be able to very easily. It's just feature.getID(), I
believe. Check the geotools api to be sure. All features, even those
with just geometries, should have the fid as their ID.
