 I have already looked into it.

On my version of Geoserver, and by following their documentation this
request should go like this:
http://192.168.1.150:8080/geoserver/wfs?request=GetFeature&typeName=topp:states&maxfeatures=10&outputFormat=GML2&version=1.1.0

(although maxfeature parameter doesn't seem to have any effect...)


After that configure your OpenLayers protocol which will be used by GeoExt

Yup, I have reconfigured the code from example to use my local Geoserver, no
problem there.

This was actually my first step. Everyone seems to recommend Firebug, as
soon as you mention "javascript" :-).

I'm still a long way away from searching through my data :-). I find this
quite frustrating. There are some examples with basic functionality, but
anything more complicated than overlaying your data over google Maps... good
luck finding that! I understand that people capable of coding such a
function do not want to "open their cards" completely, and give away for
free their hard earned knowledge, but I find it almost impossible to work
through existing documentation, and as much as I would like to _pay_ someone
to teach me these things, I haven't found anyone to pay to... As I can see,
only OpenGeo is giving commercial support, and this is only "face to face",
no "e-learning" solution...

Best regards and thanks for all your help!
