[mapserver-users] GeoJSON output from MapServer

[Dejan.Gambin at pula.hr]

Thanks Steve,

I did all that and I get:

loadOutputFormat(): General error message. OUTPUTFORMAT clause references 
driver TEMPLATE, but this driver isn't configured. 

Do I have an older MapServer version? Currently, I run this on ms4w 2.2.7 
(MapServer 5.0.2), but as I remember, I have also tried with 3.0-beta3 
(MapServer 5.4.0) and got the same result. 

Does it mean this driver is not supported in those versions?

regards, dejan
