[mapserver-users] Another newbie needing help with a mapfile (projections)...

[adams]

Dear MM,

I guess your problem is the
SHAPEPATH "."

Try first to add  the full OR relative (from where your *.map is) 
datapath in your data-statement of the layer, e.g. :

    DATA /this/is/the/path/to/mattarello.shp

If that works, add that path to your shapepath
