Dear Sir,
We have installed Mapserver-4.4.1 on Debian Knoppix version 3.4, Apache
version 1.3 with support for PostGIS. We have ESRI shapefile named
maharashtra.shp which is located in /var/www/tmp/ . Below is a  mapfile
that we have created to display this shapefile.

We have kept this mapfile in /home/indictrans/gis/mapserverdocs/workshop
. When we run this file using the following URL:

http://localhost/cgi-bin/mapserv?MODE=map&MAP=/home/indictrans/gis/mapserverdocs/workshop/font.map&layer=boundries


We get only the text layer ( Unicode characters)  on the output screen
but the image of maharashtra map (ie the shape file of maharashtra ) is
not
displayed and there is no error message also.
It is because of values of projection parameters and the extent values
of map? If yes what it should be?

Please help us in overcoming this problem as soon as possible.
