[Mapserver-users] WFS & OGR Virtual Datasource

[Van Ulden, Joost]

Ok, everything checks out with ogrinfo.

If I change the service to WMS everything works fine.  The layers show up in
Capabilities and I can do a GetMap.  Perfect.  However, if I change the
service to WFS, none of my virtual datasources show up (but all my others
do) in Capabilites nor can I do a GetFeatureInfo...  Thoughts?
