[OpenLayers-Users] Help with Openlayers & Mapserver WMS

[Julien-Samuel Lacroix]

Hi,

Your projection surely doesn't help. Your data don't seem to be in 
regular latlong. Your extents are in meter:
EXTENT 1999547.900000 5310286.800000 3001899.500000 6785629.600000

And you request a map in degree. OpenLayers assume that your requesting 
a regular EPSG:4326 and ask for a map of the following extents:
-180,-90,180,90
Example:
What OpenLayers ask for:
http://dev.asdf.co.nz/cgi-bin/wms?LAYERS=nz&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fjpeg&SRS=epsg%3A4326&BBOX=-180,-90,180,270&WIDTH=256&HEIGHT=256
What you want it to ask:
http://dev.asdf.co.nz/cgi-bin/wms?LAYERS=nz&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fjpeg&SRS=epsg%3A4326&BBOX=1999547.900000,5310286.800000,3001899.500000,6785629.600000&WIDTH=256&HEIGHT=256

Notice the BBOX?

I suggest you to find the real projection of your data (it's not 4326) 
and change that in your mapfile. You can probably use ogrinfo or QGIS to 
find it.
