[OpenLayers-Users] Cannot see Geoserver Vector Layer With WFS Protocol

Wed Oct 12 20:11:03 EDT 2011

Hi List,

I'm very new to OpenLayers, and would greatly appreciate help with what
I'm doing wrong.  I cannot get vector layers sourced from Geoserver to
display using the WFS Protocol. Please see the example below.

Thanks in advance,

David McGee
