[Featureserver] Help with FeatureServer , OpenLayers and PostGIS

[Gabriel ODUORI]

Hi Tom,

Thanks for the insight. My problems starts at the point when i want to link
OpenLayers with FeatureServer. Is there is any other configuration i need to
do apart from  featureserver.cfg file?

Looks like when i pass my url which is
localhost/featureserver-1.2/featureserver.cgi/mylayer?Format=WFS as the
source of the layers it isnt seen.


Thanks ,

Gabriel.
