Hi,
I made a test with OpenJUMP WFS plugin (http://openjump.org <http://openjump.org/> ) that is using only POST method.
For the first link GetCapabilities goes OK, but the plugin cannot parse the response correctly. Because of that I cannot send DescribeFeatureType, but when I tried GetFeature I got also "No template provided" error.
This is the request that OpenJUMP plugin is generating:
<?xml version="1.0" encoding="ISO-8859-1"?>
<wfs:GetFeature xmlns:ogc="http://www.opengis.net/ogc"; xmlns:gml="http://www.opengis.net/gml";
xmlns:wfs="http://www.opengis.net/wfs"; service="WFS" version="1.0.0" maxFeatures="1000"
outputFormat="GML2">
<wfs:Query xmlns:null="null" typeName="envirodat">
</wfs:Query>
</wfs:GetFeature>
And this is the response:
<HTML><HEAD><TITLE>MapServer Message</TITLE></HEAD><!-- MapServer version 4.8.3 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=THREADS SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE DEBUG=MSDEBUG
--><BODY BGCOLOR="#FFFFFF">mapserv(): Web application error. No template provided. <br></BODY></HTML>
The result is the same with the other URL.
OpenJUMP plugin was developed against GeoServer version 1.5, and with that it
works rather well, despite sometimes parsing errors with certain data types
(time, decimal). However, is has always had problems with all MapServer based
WFS services, including my own ones. As its best I can get GetCapabilities and
even GetFeature through, but there has always been some problems with parsing
the capabilities right, and with DescribeFeatureType. The plugin has some
tools for debugging so if someone sends me URLs I may try those and see what
happens.

Aihe: Re: [UMN_MAPSERVER-USERS] WFS POST requests: "No template provided" error
Hello Yewondwossen,
Sorry, no improvement here. I'm not getting an error, but I got a time
out, while posting (DescribeFeatureType) to the original server URL
(http://map.ns.ec.gc.ca/MapServer/mapserv.exe?map=/mapserver/services/en
vdat/config.map).
Also, the other service I mentioned,
http://www.bsc-eoc.org/cgi-bin/bsc_ows.asp, uses this same URL as online
resources, which already gave the template error.
I'm a bit out of options right now. As already mentioned, when I'm using
GET, then everything works fine, so our client will be able to access
MapServer. I'll try a few other MapServer WFS's, and see what they do.
(Using POST, and the online resource URL's.) There are quite a lot of
them online. If they all give the same result, then I'm going to file a
bug in Trac. It is no coincidence if several servers, which are set up
independently, all have the same problem.

Hi There,
WFS POST is supported by MapServer. Looking into this thread, you
mentioned a couple of URLS and I have tried the follwing one :
"http://map.ns.ec.gc.ca/MapServer/mapserv.exe?map=/mapserver/services/en
vdat/config.map"
I have tried WFS post requests describefeature and getfeature with
this service and It responds correctly. It is a Mapserve 4.8.3.
I am guessing that there is something 'wrong" with the service
accessed though the script at http://map.ns.ec.gc.ca/envdat/map.aspx
where the post requests are not maybe transfered properly to Mapserver.
Hopefully this helps.
Best Regards,

Hello Daniel,
Thanks for the reply. I've tried your suggestion, but unfortunately it
didn't work. I'm getting the following ServiceException:
<ServiceExceptionReport
xmlns="http://www.opengis.net/ogc";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/ogc
http://schemas.opengis.net/wms/1.1.1/OGC-exception.xsd";>
<ServiceException>
msWFSDispatch(): WFS server error. Incomplete WFS request: VERSION
parameter missing
</ServiceException>
</ServiceExceptionReport>
The URL is http://map.ns.ec.gc.ca/envdat/map.aspx?SERVICE=WFS&; and the
post data is the same as in the original message.
It really looks like MapServer only accepts GET request for WFS. So,
the simple fix you suggested will probably not be enough. I'm going to
file a ticket.
In case
something needs to be tested, please let me know.
Frank
