[Chameleon] RV: virtual spatial data

[Alejandro Narvaez]

More information about this

I test ovf file with ogrinfo and it is OK like with shp2img, but when I insert this url into Internet Explorer: http://127.0.0.1/fcgi-bin/mapserv.exe/?mode=map&map=map.map&LAYERS=Compress

I receive this message:

writeLog(): Unable to access file. /tmp/gmap.log msDrawMap(): Image handling error. Failed to draw layer named 'Compress'. msOGRFileOpen(): OGR error. Open failed for OGR connection in layer `Compress'. Unable to initialize ODBC connection to DSN for @access.


Any idea, 

Thanks


Alejandro

When I introduce this layer into the mapfile the Chameleon application
send this message:

Error rendering map image:
A fatal error occurred drawing the map

Since your mapfile works with shp2img, your map should load in whatever 
MapServer-application environment you use.  Maybe you should explain in 
detail what "doesn't work when I call it from my chameleon application" 
means.
