[OpenLayers-Dev] Connecting to a WFS server

[Andrés Maneiro]

Hello Xurxo,

thanks for pointing me in that direction. Nevertheless, altough I've 
tested several combinations of featureNS/featurePrefix/featureTypename, 
I didn't get the map to work, neither I understand what that parameters 
are for.

If I have URI in [1], how do I know the values of 
featureNS/featurePrefix/featureTypename?

[1] 
http://localhost:8080/geoserver/wfs?request=getfeature&typename=Galicia:CONCELLO_25 


Besides, any other help to find the bug will be very valuable.

best,
amaneiro
