I’m having trouble getting data from the Massachusetts state GIS service (http://massgis.org) to work with geoserver. I’ve attached an image of how the outline is rendered - the image should be cleanly filled in, but around the more complicated shapes it’s only drawn around the edges and sometimes overlapping the line. Is there a reason why the data would do this? Is it a configuration issue or a bug?
The shape file causing this is available here: http://www.mass.gov/mgis/outline.htm (the 100k file, not the 25k)

It could be that the shapefile outlinp1.shp has a problem, although I don’t see it in ArcMap.
I can try to load that shapefile into GeoServer as well and see what happens.
I assume you’re using the shapefile to learn GeoServer, but I should point out that if you
want to consume any of the MassGIS datalayers you can from our GeoServer.

I tried the 100k file (outlin1p.shp) and in GeoServer 1.6.0 on Windows, using a solid color fill I was not able to reproduce the problem of an incomplete fill.
It seems that shapefile (if that’s the same one you’re using) is OK.

Windows XP, using a solid color fill I was not able to reproduce the problem
of an incomplete fill. It seems that shapefile (if that's the same one

That usually happens when you try to fill a polyline as a polygon
(and the data is not really closed).
I've downloaded the data. If you try to render outlinp1 it renders
fine, if I try the same with outlina1, I get the same result as you.
This most probably means the arcs making out the linear outline
are not connected in a single outline... yeah, just checked doing
a WFS request, there are many features there, one has only a portion
of the global outline (if you want to try, use a request like
http://localhost:8080/geoserver/wfs?request=GetFeature&version=1.0.0&typeName=topp:outlina1)
When GeoServer tries to render that, each
portion gets closed by connecting the start and end point of it,
generating that weird map you got.
Use the polygonal dataset and you'll be fine.
Cheers
Andrea
