Hi,
for example at geoserver giu you have Namespace topp then you have to declare http://www.openplans.org/topp as featureNS. If you have further problems I think best way is to use the geoserver mailinglist.
Have you used pro4j for your epsg:2180 because OL doesn`t support this?
HTH
best regards
Sarah

When I change featureNS to
featureNS: "http://mapakrakow.pl:8080/komunikacja"
I get the error from firebug:
Could not locate {http://mapakrakow.pl:8080/komunikacja}przystanki_mk in catalog.
I cannt find the featureNS parameter in my Geoserver configuration. My
layer is defined in geoserver in workspace "komunikacja", layername is
przystanki_mk, EPSG is 2180. Geoserver has correctly computed
Bounding Boxes from data. Geometry columns name is the_geom,
type: Point.
Geoserver has generated layer preview:
http://mapakrakow.pl:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=komunikacja:przystanki_mk&styles=&bbox=545448.688,226900.375,586247.75,261943.359&width=512&height=439&srs=EPSG:2180&format=application/openlayers
From where should I read the featureNS?
My GML file (respond from geoserver WFS) generated as
OpenLayers.Layer.WFS works correctly and looks like:
<?xml version="1.0" encoding="UTF-8"?>
