[mapserver-users] GDal Mini drivers and php script under IIS 7 on Windows Server 2008

Thu May 7 11:41:26 PDT 2015

I am making no progress on getting this working.  I did add the error_reporting(E_All) to the script, but I don't get any errors.  From the IIS log, it looks like the server is getting the request, php must be reading the script and calling the mini driver.  It looks like the gdal mini driver is trying to read the base imagery and is failing.  Here is a piece of the IIS log:

2015-05-07 17:06:33 10.89.89.44 GET /mapserver/mapserv.exe map=content/servemap.map&service=WMS&request=GetMap&version=1.3&crs=CRS:84&layers=Land_Sea&styles=default&transparent=TRUE&format=image/png&width=512&height=512&bbox=-72.0,18.0,-36.0,54.0 80 - 10.89.89.191 Java/1.7.0_51 200 0 0 1875

If I try to send the URL from a browser, I get back an error that says this:

<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1">
<ServiceException>
msDrawMap(): Image handling error. Failed to draw layer named 'Land_Sea'.
drawGDAL(): Unable to access file. GDALDatasetRasterIO() failed: c:\MapData\Land-Sea.xml, band 1: IReadBlock failed at X offset 9, Y offset 4
</ServiceException>
</ServiceExceptionReport>

I really don't know how to troubleshoot this.  The pieces I have to work with are the map file, the layer XML files, for example Land-Sea.xml, the Tile.php script, (which seems to be working), and the tiled image set.  These same pieces work great with the same version of Mapserver, from GISInternals, on Windows 7 running IIS 7.  I'm thinking that this must be a permissions problem on Windows Server 2008.  Any ideas on where to go from here would be appreciated.
Thanks,
James

I would definitely head to the command prompt on the Windows machine, and then call php.exe through the commandline, passing it your .php file that is supposed to generate your map image, such as:

   php myscript.php

You might also make sure that your test php script shows all errors (I think it can be set directly inside your script with: 
error_reporting(E_ALL)  but I might be wrong on syntax...
