[mapserver-users] Changing to Layers.WMS from Layers.Mapserver

Fri Jul 17 07:13:01 EDT 2009

Hi, i am having trouble trying to display my map in Open Layers via OpenLayers.Layer.wms.

Firstly I Built a shape file of the UK as a raster tileindex. I can now view my map via "//localhost/cgi-bin/mapserv.exe/mymapfile.map" and the map looks fine.
I am now trying to view my map via OpenLayers. Firstly I used Openlayers.Layer.MapServer which displayed my map however zoomed in very close. However I have read Layer.Mapserver should be avoided and Layer.WMS should be used instead.  

I attempted to amend both my map and openlayers files to display via WMS by
Including:

METADATA 
      ‘wms_srs’ “EPSG: 32119 EPSG: 4326”
END
 within the WEB section of my map file and adding OpenLayers.WMS within my OpenLayers file.

However I now get the following error message within the openlayers map window “msWMSLoadGetMapParams(): WMS Server Error”

I also added ‘projection: "epsg: 32119 epsg:4326” into my openlayers file which hasn’t made any difference

Does anyone have any idea where I am going wrong? Any help greatly appreciated. My map and openlayers files are below.

Cheers

p.s. I ahve installed ms4w on windows which i tihnk supports WMS
