I’m testing the official geoserver 2.8.2 on Linux, I’ve enabled WFS-T
transactional on all workspaces.
I’m doing some insert tests using topp: roads, state_boundaries and
cities as test layers for linestrings, polygons and points.Using QGIS as a client, this works:
- insert on cities
This doesn’t:
- insert on roads and state_boundaries
First issue: geoserver returns wfs:SUCCESS/ (no errors and no warnings
in the logs) but data are not inserted in the shapefiles.By comparing example XML I’ve tracked down the problem (at least for
linestrings) to the simple GML used by QGIS, compared with the multi
geometry GML used in the geoserver demo requests (which works):QGIS (silently fails):
<the_geom xmlns=“http://www.openplans.org/topp”>
<gml:LineString srsName=“EPSG:4326”>
<gml:coordinates cs=“,” ts=" ">146.1911…GeoServer Demo Requests (works):
topp:the_geom
<gml:MultiLineString srsName="
http://www.opengis.net/gml/srs/epsg.xml#4326">
gml:lineStringMember
gml:LineString
<gml:coordinates decimal=“.” cs=“,” ts=" ">146.1911…What geometry type is GeoServer declaring in DescribeFeatureTypeã If they
do not match you’ll
get the result you are describing.As far as I know the original developer of the WFS-T subsystem said we
cannot xml validate the
request for some reason, but at the same time the parser is unfortunately
schema driven,
meaning that it will only look for the elements it expects to find,
ignoring the others.
So if it’s looking for a attribute that’s not mandatory, and does not find
it because it’s mis-encoded,
the transaction will succeeded ignoring the unexpected attributes.We have had a number of reports due to this issue over the years, with a
few variants (e.g., people encoding
geometries in gml 2 in wfs 1.1 transactions), and I agree it would be best
if the
system validated the input xml against the expected schema and threw an
error,
but apparently it’s not an easy thing to fix (meaning, not a spare time
deal),
and one that nobody has gathered funds to use working hours to fix so far.Cheers
Andrea
Thank you Andrea,
I have clear picture now, and you are right, the problem is in that
DescribeFeatureType returns type=“gml:MultiLineStringPropertyType” while
QGIS thinks that is a simple geometry.
I’ll have a look into QGIS if we can do something to fix this.

Hi,
If you restrict your output to openlayers (which isnãt ?reallyã an output format), you wonãt be able to even use the resulting output. The openlayers output format is what generates the layer
previewer which is actually an html page with embedded javascript. Ultimately, the page makes WMS requests for the jpg/png etc formats. So, you would want to have them available as well.

Hi,
- Disabling WFS shouldn’t stop the Layer Preview from working.
- Restricting access to only certain output formats - http://osgeo-org.1560.x6.nabble.com/WMS-output-format-restrictions-td3796402.html
- Are you sure you want OpenLayers as the output formatã If you’re building your own application that application will be openlayers (or whatever), and the data it uses will mostly be png8, (or jpeg
for imagery).
Cheers,
Jonathan

Dear all,
I am hitting my head in a wall trying to figure out how to manage the web services.
My goals:
1 - To make just one specific layer available for visualization only (no download available);
2 - To provide only OpenLayers for the Output Formats on WMS services.
My issue:
Making the service WFS unable is making all the layers in the layer preview unable.
Could anyone help me to figure out how to configure geoserver in order to publish data just for visualization through OpenLayers WMS onlyã
