Hi,
I would suggest to test test the WFS service first by using something that you can control. Myself I would do that by making WFS requests manually with text editor and sending them through browser. To begin with:
http://localhost:8080/geoserver/wfs?service=WFS&version=1.0.0&request=GetCapabilities
http://localhost:8080/geoserver/wfs?service=WFS&version=1.0.0&request=DescribeFeatureType
http://localhost:8080/geoserver/wfs?service=WFS&version=1.0.0&request=GetFeature&typename=namespace:your_type&maxfeatures=100
Is these request work you can be pretty sure that everything is OK with your Geoserver. You can continue by adding BBOX and try also version 1.1.0. Version makes a lot of difference because it is changing x- and y-axes.
Once you know that Geoserver works you can concentrate on the client side and make it to send reasonable requests.

Aihe: Re: [Geoserver-users] OpenLayers WFS GetFeature
returning nothing
Hi all,
I have the same problem: I'm getting no WFS features from
Geoserver (using
Openlayers utilities for javascript).
I'm sure the javascript code is right (I took it from an
OpenGeo example),
and it's not a matter of amount of information (it's all
about 13 points).
I'm stuck with this problem form 3 deadly days, and I was
wondering if you
Community have some suggestion about it...? P
Some detail:
- I want to see points (towns..) over a Goggle Map;
- if I ask for a png WMS map, then I can see the points over
the baselayer,
but if I ask for the same point "as feature" with WFS I see only the
GoogleMap;
- even if I retrieve the points via WMS, I cannot see the
attributes related
to them (I defined an 'on-click' event);
- Firebug doesn't show warnings;
- if I look into the variable wfslayer (via Firebug), I can
see it has no
feature ();
- in the logfile of Geoserver I can see that the http
response code is ok
(200) but 0 byte are returned, as a proof of the clear fact
that no feature
is returned.
God bless you in advance.
