[mapserver-users] mapscript owsdispatch does not work, cgi mapserver does

[Jachym Cepicky]

Hi,

I have strange problem, I need to use mapobject.OWSDispatch with WMS
GetMap request, and I do expect image at the output.

I have prepared small python wrapper script, which should load the
mapfile, perform owsdispatch and return the result. It does not work
(saying something about missing xerces support, which is not true, see
below).

When I use *exactly the same* mapfile, but with simple shell wrapper
(so no mapscript), it works perfectly.

Examples:

(1) Shell script wrapper:

#!/bin/sh
export MS_MAPFILE="/tmp/wfs02.map"
/usr/lib/cgi-bin/mapserv

http://localhost/cgi-bin/owsviewer2.sh?LAYERS=kraje&TRANSPARENT=TRUE&FORMAT=image%2Fpng&EXCEPTIONS=XML&VERSION=1.3.0&STYLES=default&CRS=EPSG%3A4326&SERVICE=WMS&REQUEST=GetMap&BBOX=49,12,51,18&WIDTH=1000&HEIGHT=634

-> Image is returned



(2) Python script:

#!/usr/bin/python
import mapscript
mapobj = mapscript.mapObj("/tmp/wfs02.map")
request = mapscript.OWSRequest()
request.loadParams()
print mapobj.OWSDispatch(request)

http://localhost/cgi-bin/owsviewer2.py?LAYERS=kraje&TRANSPARENT=TRUE&FORMAT=image%2Fpng&EXCEPTIONS=XML&VERSION=1.3.0&STYLES=default&CRS=EPSG%3A4326&SERVICE=WMS&REQUEST=GetMap&BBOX=49,12,51,18&WIDTH=1000&HEIGHT=634

->

What am I doing wrong?

Thanks
