Hi, I'm trying to get a simple OL application to display a mapserver mapfile, but all I get is the grey background for the image, and a the embedded scale bar displaying much smaller linear measurements than the static mapserver file (0.2 vs 16 km). I have specified for the OL map projection to be UTM 32N (Epsg: 22332) and meters for Units. I don't understand why the display coordinated for the mouse position are still LatLon and why the map data won't display. It's reading the mapfile, but I don't know why I won't display the raster or verctor data. any suggestions?
JS CODE
map = new OpenLayers.Map('map', { projection: new
OpenLayers.Projection("EPSG:22332"),
displayProjection: new
OpenLayers.Projection("EPSG:22332"), units: "meters"});
layer = new OpenLayers.Layer.MapServer( "Jerba",
"http://localhost/cgi-bin/mapserv";, {map:
'/home/mapdata/jerba.map', layers: "satt"} );
map.addLayer(layer);
map.zoomToExtent( new OpenLayers.Bounds (629664.75,
3694383.75, 718556.25, 3770763.75));
map.addControl( new OpenLayers.Control.LayerSwitcher()
);
map.addControl( new OpenLayers.Control.MousePosition() );
map.addControl( new OpenLayers.Control.OverviewMap() );
map.addControl( new OpenLayers.Control.ScaleLine() );
