[TinyOWS-users] Some difference between clients WFS.

Sun Sep 4 04:19:26 EST 2011

Hi,

I have installed Fiddler 2 for capturing the traffic between client and TinyOWS. It records also all the POST requests and it is possible to edit those and resend afterwards. There are for sure other similar programs but Fiddler was the first I tried and it works fine. I would say that it is almost impossible to understand what is happening without such a tool.

But after these errors Kosmo seem send the right request and TinyOWS send the GML asked.

I don't know if the error of Kosmo requests are really error or incompatibility with TinyOWS.

Hi,

effectively...
I re-install Kosmo and now it work well....
I don't know why but however now it work also for me.

Thanks for response.
Surely I do a bugged operation.
I'm afraid and sorry for noise.

Hi,

Sorry, I do not quite understand but let's take an example. This is my layer

<layer retrievable="1"
    writable="1"
    ns_prefix="tows"
    ns_uri="http://www.tinyows.org/"
        name="france"
        title="French Administrative Sub Boundaries (IGN - GeoFLA Departements)" />

Service is at http://188.64.1.61/cgi-bin/tinyows.

Do you have troubles with Kosmo? For me it works OK.

Aihe: [TinyOWS-users] Some difference between clients WFS.

Hi,
I have download and try-ed the Kosmo GIS and it wfs plugin.

Indeed the wfs plugin of kosmo seem more sophisticated of the wfs plugin of wgis.
But I found a little ingenuity.

Kosmo wfs client use the
layer ns_prefix as table-name.

qgis wfs plugin insted use the attribute "name"

 notice this because

In my test a put the real name of the table in "name" attribute and use a mnemonic identify in the ns_prefix.
The result is that qgis wfs plugin will show me the data, insteed
kosmo plugin give me an error.
Kosmo show the dtaa only if I put the real name of the table in the "ns_prefix" field.

I guess the right choice is that of qgis,
is this correct ?

Thx,
