Hi Jeff,
if I use the following MAP file I get the correct GML in my temp directory
and an Image. Note that I use a MAXFEATURES to prevent getting a timeout.
BTW Try removing your METADATA and see if that works, or fill in the
complete metadata (including at least wfs_service, wfs_typename).
NAME "sample client"
STATUS ON
SIZE 400 300
#SYMBOLSET "../etc/symbols.sym"
EXTENT 76.1 -69.4 76.4 -69.2
UNITS METERS
SHAPEPATH "../data"
IMAGECOLOR 255 255 255
#FONTSET "../etc/fonts.txt"
IMAGETYPE PNG24
WEB
IMAGEPATH "/ms4w/tmp/ms_tmp/"
IMAGEURL "/ms_tmp/"
END
PROJECTION
"init=epsg:4326"
END
LAYER
NAME popplace
CONNECTIONTYPE WFS
CONNECTION
"http://aadc-maps.aad.gov.au/geoserver/wfs?VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=topp:ICEBERG_PY&MAXFEATURES=100"
TYPE POLYGON
STATUS ON
PROJECTION
"init=epsg:4326"
END
CLASS
NAME "test"
COLOR 255 0 0
END
END
END
Best regards,
Bart
