[MS4W-Users] MS4W -- Shapefile not drawing via mapserver

[krisk82 at gmail.com]

Hello:

Right now I'm trying to build a static map and from there build an
interactive map--similar to the MS4W tutorial that came with the
installation. I have had issues with Mapserver NOT drawing the polygons
associated with my shapefile.

Here are some details of my setup:

MS4W - MapServer 4 Windows - version 3.0.6
> MapServer CGI 6.0.3 at /cgi-bin/mapserv.exe
>

My apache configuration to point to the web app folder is fine. Here is the
fiile path on my HDD. To connect to the web app webpage I visit:
http://localhost/testpage/

Location of mapfile    -->  C:\ms4w\apps\testpage\htdocs
> Location of shapefile  --> C:\ms4w\apps\testpage\htdocs\data\land_poly.shp
>
When I try to access the image via url (
http://localhost/cgi-bin/mapserv.exe?MAP=/ms4w/apps/testpage/htdocs/kristenmap.map&layer=land&mode=map),
I receive the following error:

*msDrawMap(): Image handling error. Failed to draw layer named 'land'.
msShapefileOpen(): Unable to access file.
(/ms4w/apps/testpage/htdocs/land_poly) msShapefileOpen(): Unable to access
file. (/data/land_poly) *

That lead me to see what was going on via shp2img, using "-map_debug 3"
parameter. shp2img.exe returned to me the following responses:

C:\ms4w\Apache\cgi-bin>shp2img -m
> c:\ms4w\apps\testpage\htdocs\kristenm c:\ms4w\apps\testpage\htdocs\test.png
> -map_debug 3
> msDrawMap(): rendering using outputformat named png (AGG/PNG).
> msDrawMap(): WMS/WFS set-up and query, 0.000s
> msDrawMap(): Drawing Label Cache, 0.000s
> msDrawMap() total time: 0.000s
> msSaveImage(c:\ms4w\apps\testpage\htdocs\test.png) total time: 0.141s
>

It looks like the shp2img is probably running into the same error--not
being able to find the shapefile. The PNG file that shp2img creates is just
a blue rectangle (blue is the map image background). I am not sure what is
going on with the shapefile file paths.  In my map file I indicated "
SHAPEPATH    "/data/". Here's the mapfile in its entirety. Hopefully, this
is a pretty small fix and that someone can help me out. THANKS!

Thank you in advance!
