[mapserver-users] Re: MapScript WMS request
a bit more investigation on producing a WMS response via Perl MapScript reveals
the following error
?xml version='1.0' encoding=ISO-8859-1 standalone=no ?
!DOCTYPE ServiceExceptionReport SYSTEM
http://schemas.opengis.net/wms/1.1.0/exception_1_1_0.dtd;
ServiceExceptionReport version=1.1.0
ServiceException
msWMSDispatch(): WMS server error. WMS request not enabled. Check
wms/ows_enable_request settings.
/ServiceException
/ServiceExceptionReport
So, it seems I have to somehow, somewhere enable 'ows_enable_request'. Looking
at the documentation, seems like if I had a map file, I could add the following
line to do so
ows_enable_request '*'
However, I am not using a map file at all. Not finding any documentation on
this setting, I tried the following to no avail
$map-{ows_enable_request} = '*';
Suggestions, anyone?

Re: [mapserver-users] Re: MapScript WMS request
in PHP MapScript should be something like
$map-setMetaData(ows_enable_request, *);
in Python:
map.setMetaData(ows_enable_request, *)

Puneet,
I rarely use PHP and it is possible something is broken now with PHP
OWS dispatching. But it should work like:
http://mapserver.org/ogc/mapscript.html#php-example
Alternatively if you don't install the stdout redirection the OWSDispatch
call should produce the image to stdout.
Note that if you want things handled properly as a WMS request you should
not be calling draw(). The ticket you reference long predates the WxS
MapScript services effort.
I suspect you are not really setting all the environment variables needed
to make the WMS handler kick in during OWSDispatch though I'd have to
play around with it to be sure.
Best regards,
