[mapserver-users] perl mapscript [SEC=UNCLASSIFIED]

I asked Justyna to send me a testcase. I was able to reproduce the issue.
When I run the mapfile through shp2img, I get a projection not found error. When I check MAP.PROJECTION, the value is "init=EPSG:26915".
The "EPSG" should be in lower case ("init=epsg:26915"). When this change is made, shp2img, and the Perl mapscript, runs fine
If you are running this off the command line, you have to set MAP.WEB.METADATA.ows_onlineresource (MapServer gets the default value from http environment variables, if not specified).
Can you try this and see if it works?

Hi,
Putting in the full path to the mapfile makes no difference the same
errors occur. Are the errors for setParameter a red herring?
Interestingly I've tried handing it both a valid map filename and a
filename that doesn't exist. When the mapfile doesn't exist it reports
"Mapfile error: No such file or directory". When the map file does
exist it doesn't report on the nature of the problem, but clearly it is
finding the file otherwise it would report "No such file or directory".
See below.
Is anyone using perl mapscript to do WxS services on mapserver 5.2?
======================================
Using no.map, which doesn't exist
======================================
$ ./minimal_wms.pl
Cannot setParameter SERVICE:
Cannot setParameter VERSION:
Cannot setParameter REQUEST:
Mapfile error: No such file or directory
Can't call method "OWSDispatch" without a package or object reference at
./minimal_wms.pl line 13.

Using minimal_wms.map
======================================
./minimal_wms.pl
Cannot setParameter SERVICE:
Cannot setParameter VERSION:
Cannot setParameter REQUEST:
Mapfile error:

./minimal_wms.pl line 13.
#!/usr/bin/perl
use mapscript;
$req = new mapscript::OWSRequest( ) or warn "Cannot create request:
$!\n";
$req->setParameter( "SERVICE", "WMS" ) or warn "Cannot setParameter

$req->setParameter( "VERSION", "1.1.0" ) or warn "Cannot setParameter

$req->setParameter( "REQUEST", "GetCapabilities" ) or warn "Cannot

#$map = new mapscript::mapObj( "no.map" ) or warn "Mapfile error: $!\n";
$map = new mapscript::mapObj( "minimal_wms.map" ) or warn "Mapfile
error: $!\n";
$map->OWSDispatch( $req );

The mapfile can't be found. Try changing this line to:
$map = new mapscript::mapObj( "minimal_wms.map" ) or warn "mapfile
error: $!\n";
..and you'll see the error.
Try pointing to the mapfile fullpath?
