There are several possibilities, but a common problem in this situation
is that someone will add their data to a demo application, but not
modify the EXTENT in the map file to reflect the area in which their
data is located. In other words, if the EXTENT of original application
is defined as a box around the continental US and you add a valid data
layer of Italian wine regions, you will not see your new layer because
it falls outside of the extent.
You can get the extent of your data by downloading OGR from
http://ogr.maptools.org/ and running ogrinfo on the data file.
A second common issue is that if you are trying to add your data to an
existing map file, your data may be in another projection. MapServer
can handle on-the-fly reprojection, but that requires you to add a few
projection blocks to your mapfile.

Subject: [UMN_MAPSERVER-USERS] No Map??
Hello, here is our problem.
We are using the Windows compiled version of the software.
Using the examples in the software we attempted to load our own map.
Everything appeared to load fine but there is no map in the display just
the empty box. All the tools were present and no error messages were
Any help would be much appreciated.
