[mapserver-users] Question about MapServer

[Jorge Arévalo]

Hello,

I'm executing Mapserver 5.6.4 under Apache2 in a Ubuntu 10.04 machine.
I'm having problems with a SLD file. Basically, when I execute a
request like this:


http://myserver/cgi-bin/mapserv?map=/var/mapserver/mapfiles/sld_cookbook_polygon.map&service=WMS&version=1.1.1&request=GetMap&layers=sld_cookbook_polygon&sld=http://myserver/sld/polygon_simplepolygon.sld

I get this error:


<?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>

http://myserver/sld/polygon_simplepolygon.sld and save it in temporary
file /var/mapserver/output/4df778fc_14b7_0.sld.xml. Please make sure
that the sld url is valid and that imagepath and imageurl are set
properly in the map file

curl error code 7 (Failed connect to agropilot:80; Operation now in
progress) for http://myserver/sld/polygon_simplepolygon.sld
</ServiceException>
</ServiceExceptionReport>

The log file shows this:

The IMAGEPATH and IMAGEURL vars have a valid value in mapfile:

IMAGEPATH "/var/mapserver/output"
IMAGEURL "http://myserver/output"

The output directory exists and is writable by www-data (even when I
change permission to 777, the same error); http://myserver/output is
reachable. The curious thing is the file
/var/mapserver/output/4df778fc_14b7_0.sld.xml is actually created, but
it's empty.

I had problems before because apparmor didn't allow writing in
/var/www, but I changed the apache directory to /var/mapserver, and
now apache can write on it. In fac, it's writting a log file. I don't
understand this error. Any idea?

Many thanks in advance, and best regards,
