[Qgis-user] qgis server does not return any data from WFS

[Jachym Cepicky]

Andreas,

thanks for clarification: I've not tedste GetPrint yet. Yes, GetMap works
(without DISPLAY set)

about location of .qgs file - I just use it locally, try to get owslib to
work along with QGIS-WFS Server, so just for testing so far, but thanks for
reminding me

Jachym
