Win XP and paths in the .map file

[Jacob Delfos]

Manuel,

I have had similar problems using IIS 6 on Windows Server 2003. The configuration of IIS is a bit confusing, and I haven't figured out the problem yet. Only thing you could check is to make sure that you got your execution permissions set up correctly. You may have to add your mapserver executable to the pool of programs that is allowed to run on the server, and then also specify for each directory that mapserver is allowed to run in there (it's kind of doubled-up in IIS). Aside from that it's still a mystery to me. I use the a similar configuration on win2k without problems. XP and 2003 server have a different configuration. Specifying IUSR permissions does not seem to suffice.

I would suggest you make your shapepath absolute, though. To make sure there is no confusion about relativity to the webroot, or the executable path.

Jacob

P.S. be aware of the 10 user connection limit with IIS, on a non-server version of windows. May be better of using apache.

You are right in thinking that this is probably a permissions problem.
Be sure that the IUSR account has read access to that particular file; I
think permission settings are the most common cause of problems when
migrating from one machine to another "identical" one.

Separately, it might not be the best idea to store your shapefiles in
the wwwroot tree if you want to protect them from being accessed outside
of MapServer.  It's usually wise to place MapServer's data files safely
outside any place that grants access to Web users.

Good afternoon:

I have been running MapServer 4.2.0 in Windows 2K and that works OK. I
have copied my application to Windows XP SP2 and configured all the
permissions, etc. as I did on Windows 2K, and now it seems that
MapServer is unable to read the paths from in the .map file. The .map
file contents
are:

NAME satgeobase
 SHAPEPATH "shapefiles/satgeobase"
 UNITS meters
 IMAGECOLOR 255 255 255
 TRANSPARENT ON
 SYMBOLSET symbols/symbols.sym

LAYER
 DEBUG on
 NAME countries
 TYPE polygon
 STATUS ON
 DATA "cntry98"

  CLASS
   NAME "Country outline"
  COLOR 255 255 255
  OUTLINECOLOR 255 255 0
  END
END

END

If I type the following line in Internet Explorer:

http://127.0.0.1/mapserver/mapserv.exe?
map=c:\Inetpub\wwwroot\satgeobase.map&mode=map&layer=countries&imgsize=8
00+
400&mapext=-180+90+180+-90

Map Server returns:

msDrawMap(): Image handling error. Failed to draw layer named
'countries'.
msSHPOpenFile(): Unable to access file. (c:\Inetpub\wwwroot\cntry98)
msSHPOpenFile(): Unable to access file.
(c:\Inetpub\wwwroot\shapefiles/satgeobase/cntry98)

If I change the SHAPEPATH line to SHAPEPATH "shapefiles\satgeobase\",
then the result is:

msDrawMap(): Image handling error. Failed to draw layer named
'countries'.
msSHPOpenFile(): Unable to access file. (c:\Inetpub\wwwroot\cntry98)
msSHPOpenFile(): Unable to access file.
(c:\Inetpub\wwwroot\shapefiles\satgeobase\cntry98)

I have tried to use double backslash, double forwardslash and many
combinations, but it seems that MapServer.exe cannot find the shape
files.
The shapefiles exist, names and paths are correct, the default firewall
that XP sets up is disabled, and I have even given administrative rights
to the IUSR_<> user, just in case. I get the same result, the same
answer that MapServer gives when the files do not exist.

Does anyone know if this is a known problem? Any ideas?

Thanks very much in advance,

Manuel
