Hi,

You must capture the traffic between OpenLayers and TinyOWS.  I am using myself Fiddler2 proxy but I suppose that Firebug can show you what OpenLayers is sending and high enough TinyOWS logging level will also gather requests into tinyows log. The software is not important but you just have to get the requests so you can resend them with a browser or some other tool that yuo can control and see what happens. You can also include the requests in your further mails. Then the question will be "OpenLayers is sending this and TinyOWS is sending back that, what's wrong?" and it will be much easier to answer.

As always with WFS, start with these requests with a browser before doing anything with OpenLayers:
http://127.0.0.1:8000/redir/cgi-bin/tinyows.exe?service=wfs&request=GetCapabilities&version=1.1.0

http://127.0.0.1:8000/redir/cgi-bin/tinyows.exe?service=wfs&request=DescribeFeatureType&version=1.1.0&typename=water:pipeline_segment

http://127.0.0.1:8000/redir/cgi-bin/tinyows.exe?service=wfs&request=GetFeature&version=1.1.0&typename=water:pipeline_segment&maxFeatures=10

If all those requests work you know that TinyOWS works with those basic requests and if OpenLayers application does not get data the reason in probably in the application code.

> which looks acutally quite good. But when i am trying to include that
into my openlayer map - I always get 0 features back! Here the code for
openlayers:

wfs = new OpenLayers.Layer.Vector("Editable Features", {
         strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy],
         projection: new OpenLayers.Projection("EPSG:31467"),
         protocol: new OpenLayers.Protocol.WFS({
               version: "1.1.0",
               srsName: "EPSG:32740",
               url: "http://127.0.0.1:8000/redir/cgi-bin/tinyows.exe",
               featureNS :  "tows",
               featureType: "pipeline_segment",
               geometryName: "geometry",
               schema:
"http://127.0.0.1:8000/redir/cgi-bin/tinyows.exe?service=wfs&request=DescribeFeatureType&version=1.1.0&typename=water:pipeline_segment"
         })
});

Someone an idea?
