Hi Jukka,
thanks for your tips! But I don´t know where I am now. I think the
host-problem was because of a wrong usage of wget. Anyhow - now it seems
like I don´t have a problem anymore, which is not much better. Or at
least I can say its a problem of openlayers?!...
I send:

and so on...
so now I know - my problem is not in the configuration of my tinyows.xml
and the get request is constructed correctly from my openlayers code. So
where is this error that there is an invalid parameter which is always
returned in my test.html when i am sending the same get feature request?

Hi,
On this page there are some WFS calls which do work against my TinyOWS server

A very easy to use tool for testing POST requests is the Poster Firefox

Something is wrong with the host - maybe there is something missing in the
tinyows configuration. Because now wget takes the application as the
address instead of the coordinates of the bounding box!?
I took the same ns_prefix: feature because its also defined like that in my
xml -- I changed it, because i read that recommendation somewhere - made
no difference.

Anna,
What does your C:\ms4w\Apache\logs\tinows.log file contain ?
Also yeah you should use --post-data='<wfs:GetFeature...' and not
--post-data="<wfs:GetFeature...". If your dataset isn't too big, you
could remove the <ogc:Filter> node. Also, try replacing
xmlns:feature="http://127.0.0.1/"; by xmlns:tows="http://127.0.0.1/";.

Hi Alexandre,
I already reinstalled pyhton and made the configuration of the apache

sooner or later I have to include it in another project which needs

are right, it helps a lot.

I have really no idea why it is using the coordinates of the bounding
box for the host?! I thought it would be a problem of wget and the
quotation marks... but changing that to ' did not solve the problem.
In my test.txt is still the same response: invalid xml. Nothing else
unfortunately. I think its a problem in my openlayers configuration -
I check the spatial reference again; maybe I can also set the bbox or
something. I will see...
If you or anyone else has an idea I will be very happy!

Hi Anna,
While working locally, you don't need to set an
OpenLayers.ProxyHost. Put comments // in front of it for now.
tinyows-1.0.0-weather-sites.fcgi -> copy your tinyows.exe file
giving it the name you want. In Linux, you could use a symbolic
link, like I did. Here's the apache config for it. It does 2 things
: it enables FastCgi and set the TINYOWS_CONFIG_FILE env variable
for this link to use a specific .xml config file.
###
FastCgiServer /usr/lib/cgi-bin/tinyows-1.0.0-weather-sites.fcgi
-initial-env
TINYOWS_CONFIG_FILE=/opt/labs/weather-
sites/etc/tinyows/config.xml
ScriptAlias "/weather-sites-tinyows-1.0.0.fcgi"
"/usr/lib/cgi-bin/tinyows-1.0.0-weather-sites.fcgi"
###
Once you start using wget, the idea is to edit the xml GetFeature
request sent and/or the config.xml file as you try it to quickly see
what causes things to not work. Point to tinyows for now, you your
proxy (yet), i.e. make your tinyows work first.
Best regards,
Alexandre

Hi Alexandre,
thanks for the good hints! This is really great! I think its not my
tinyows.xml or the Openlayers... but the error message tells
something else somehow... :(... I changed it to the following:

</tinyows>
and the OpenLayers code:
map = new OpenLayers.Map('map', {
projection: new OpenLayers.Projection("EPSG:31467"),
units: "m",

maxExtent: new
OpenLayers.Bounds(3427000,5788000,3444000,5800000),

new OpenLayers.Control.PanZoom()
]
});
var osm = new OpenLayers.Layer.WMS(
"OSM by Omniscale WMS",
"http://osm.omniscale.net/proxy/service";,
{layers: 'osm', format: 'image/jpeg'},
{projection:"EPSG:31467", units: "m", maxResolution: "auto",
maxExtent: new
OpenLayers.Bounds(3427000,5788000,3444000,5800000)}

var saveStrategy = new OpenLayers.Strategy.Save();
saveStrategy.events.register("success", '', showSuccessMsg);
saveStrategy.events.register("fail", '', showFailureMsg);
var wfs = new OpenLayers.Layer.Vector("Editable Features", {

projection: new OpenLayers.Projection("EPSG:31467"),

readFormat: new OpenLayers.Format.GeoJSON(),
featureNS: "http://127.0.0.1/";,
geometryName: "the_geom"
})
});
map.addLayers([osm, wfs]);
map.zoomToMaxExtent();
The layer is actually in 31467 - I want to get it working for the
frida parks example. I reduced everything else in my javascript file.
But I think I have a problem with my configuration. I am setting
the following in OpenLayers: OpenLayers.ProxyHost =
"/cgi-bin/proxy.cgi?url="; and I saw that you were actually
refering to a fcgi file in your config.xml. I thought I could
define there the path to the tinyows.exe like this:
http://127.0.0.1/cgi-bin/tinyows.exe - do I also give the proxy there?
Could you send me the content of your
weather-sites-tinyows-1.0.0.fcgi file? I have to say that I can´t
follow your instructions for setting the environment variable - I
made that via the control Panel :) - and the ScriptAlias.
I have to install the wget first on windows, but thanks for that
hint - I will try it after the restart now!
Thanks in advance,
Anna
