Description
GvSIG 2.0 alpha 4 cannot get data from this WFS service
http://188.64.1.61/cgi-bin/tinyows?service=wfs&version=1.1.0&request=getcapabilities
The feature type I tried is "municipalities". Older gvSIG version 1.11 reads data OK, as well as Kosmo GIS, Quantum GIS, GDAL/OGR 1.9.0 and many others. The error I get makes me think that problem may have something to do with the default SRS, which is <DefaultSRS>urn:ogc:def:crs:EPSG::3067</DefaultSRS>

- Priority changed from Normal to Urgent
#2 Updated by Antonio Falciano about 12 years ago
The same behavior happens in gvSIG 1.11 (build 1305) and gvSIG 1.12 (build 1206) with the following service (WFS v. 1.1.0):
http://wms.pcn.minambiente.it/cgi-bin/mapserv.exe?map=/ms_ogc/wfs/Autorita_bacino.map
The alphanumeric data are loaded, while geometries not.

Hello,
It works also in EPSG:4326 (not sure who is reprojecting, but it works)
See attached image "finland.jpg"
Can we close this ticket?
#10 Updated by Juan Lucas Domínguez almost 12 years ago
I have tested it with build 2049 and it works.
Why is it not closed?

1.- Open gvSIG BN 2051
2.- Open new view (23030)
3.- Add new layer--> WFS / http://188.64.1.61/cgi-bin/tinyows?service=wfs&version=1.1.0&request=getcapabilities/ Next/Next
4.- Enable Show layer names and select Layer= municipalities
5.- Click Next, check that appears by default srs=EPSG 3067, you can't change.
6.- Click Ok
A warning message and isn't displayed WFS layer

This seems to happen because the connection URL contains the request=getcapabilities part
http://188.64.1.61/cgi-bin/tinyows?service=wfs&version=1.1.0&request=getcapabilities
gvSIG creates the following request
service=wfs&version=1.1.0&request=getcapabilities&REQUEST=GetFeature&SERVICE=WFS&TYPENAME=lv:municipalities&PROPERTYNAME=lv:suuralue,lv:avi,lv:maakunta,lv:seutukunta,lv:kunta,lv:suural_ni1,lv:suural_ni2,lv:avi_ni1,lv:avi_ni2,lv:maaku_ni1,lv:maaku_ni2,lv:seutuk_ni1,lv:seutuk_ni2,lv:kunta_ni1,lv:kunta_ni2,lv:kieli_ni1,lv:kieli_ni2,lv:kaupunki,lv:shape_leng,lv:shape_area,lv:the_geom&VERSION=1.1.0&EXCEPTIONS=XML&MAXFEATURES=1000&NAMESPACE=xmlns(lv=http://latuviitta.fi/)&RESULTTYPE=hits
There are both request=getcapabilities and REQUEST=GetFeature. TinyOWS server is sending back answer to getcapabilities while gvSIG is awaiting answer for GetFeature&RESULTTYPE=hits.
Without request=getcapabilities in the connection string everything seems to work OK. I do not know what server should do in this case. It would be most safe if gvSIG would not send the unnecessary request=getcapabilities.
#16 Updated by Jukka Rahkonen over 11 years ago
More information: If I try to read a layer from WFS with the URL which contains that unnecessary "getcapabilities" then gvSIG starts to behave very badly. If I click on the table of contains for removing the layer the CPU load is reaching 100% for a long time. The whole computer gets jammed and the only way to continue seems to be to kill the gvsig-desktop.exe process from task manager.
I tested this with Windows XP and gvSIG 2.0.0 2051 win-x86-standard-withjre.
#17 Updated by Juan Lucas Domínguez over 11 years ago
Thanks Jukka for those tests.
Note for myself: A.Falciano's issue is probably caused by an error in: org.gvsig.gpe.prov.gml.parser.v2.geometries.MultiPolygonTypeBinding, parseTag
#18 Updated by Juan Lucas Domínguez over 11 years ago
I don't think this is really a bug because the URL used is not right and the server is not behaving properly (I think it should not accept two occurrences of "request"). I have added a warning to the user if a suspicious string is found in the URL.
Nevertheless, there is still a problem described by Antonio Falciano which I will address soon.
#19 Updated by Jukka Rahkonen over 11 years ago
Hi,
It is perhaps not so straight forward. It is true that the URL used for making connection is odd. However, it does return a valid GetCapabilities response and if you see inside the document http://188.64.1.61/cgi-bin/tinyows?service=WFS&version=1.1.0&request=GetCapabilities there are these entries:
<ows:Operation name="GetFeature">
<ows:DCP>
<ows:HTTP><ows:Get xlink:href="http://188.64.1.61/cgi-bin/tinyows?"/>
</ows:HTTP>
</ows:DCP>
<ows:DCP><ows:HTTP>
<ows:Post xlink:href="http://188.64.1.61/cgi-bin/tinyows"/>
</ows:HTTP>
</ows:DCP>
If WFS standard is followed strictly the client should use those URLs which are advertised in the GetCapabilities and not just simply use the same base URL that was used for GetCapabilities.
It is known that GetCapabilities can advertise wrong URLs for GetFeature (and same with GetMaps in WMS services). Some WMS clients are asking user to select between the same base URL used for GetCapabilities of the URL that comes with the GetCapabilities response. Perhaps WFS client could behave in a similar way too.

- Status changed from New to Fixed
Added parsing for the surfaceMembers element (multipolygon).
Unfortunately, in server:
http://wms.pcn.minambiente.it/cgi-bin/mapserv.exe?map=/ms_ogc/wfs/Autorita_bacino.map
only EPSG:4326 is available (using new order: first latitude then longitude) so gvSIG paints it flipped (see image italy-flipped.jpg)
#22 Updated by María Maluenda over 11 years ago
- Status changed from Fixed to Closed
Closed in the gvSIG build 2056.
I tested:
1.- Open gvSIG BN 2056
2.- Open new view (23030)
3.- Add new layer--> WFS / http://188.64.1.61/cgi-bin/tinyows?
4.- Enable Show layer names and select Layer= municipalities
5.- Click Next, check that appears by default srs=EPSG 3067, you can't change.
6.- Click Ok
Layer is loaded ok
