Hi,
Since your problem is related to OpenLayers you may get more help from
the OpenLayers Users mailing-list.
Anyway, to have OpenLayers call the right projection use (replace
EPSG:12345 by your actual projection code):
var options =
{
scales: [3500000,
3000000,2500000,2000000,1500000,1000000,350000,250000],
maxScale: 250000,
minScale: 3500000,
projection:"EPSG:12345",
displayProjection: "EPSG:4326",
units: "m",
controls: [new OpenLayers.Control.MouseDefaults()]
};

Hi!
I provide you my OpenLayers code.
function init()
{
OpenLayers.DOTS_PER_INCH = 72;
// --------------------------------------------------------------------------//
// Tableau des options pour la carte.

// La plus importante est scales qui permet de definir les
différents zooms //

--------------------------------------------------------------------------//
var options =
{
scales: [3500000,
3000000,2500000,2000000,1500000,1000000,350000,250000],
maxScale: 250000,
minScale: 3500000,
controls: [new OpenLayers.Control.MouseDefaults()]
};
// -------------------------//
// Création de l'objet map. //
// -------------------------//
map = new OpenLayers.Map( 'map',options);
// ----------------------------------------------//
// On ajoute les couches après les avoir créées. //
// ----------------------------------------------//
layer = new OpenLayers.Layer.MapServer( "OpenLayers WMS",
"http://localhost/cgi-bin/mapserv?mode=map&map=/var/www/html/ms/map_files/france.map";, {layers: ['FRANCE','CORSE']},
{gutter: 0 });
map.addLayer(layer);
}
//
-----------------------------------------------------------------------//
// Ajout de la barre de zoom et des coordonnées de la position
actuelle. //
//
-----------------------------------------------------------------------//
map.addControl( new OpenLayers.Control.PanZoomBar() );
// ------------------------------//
// Ajout de la gestion du click. //
// ------------------------------//
var click = new OpenLayers.Control.Click();
map.addControl(click);
click.activate();
// ---------------------------------------------------------------------------//
// Et on définit le centre de notre carte, afin qu'elle sot bien
positionnée. //
//
---------------------------------------------------------------------------//
map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
And my mapfile has the good projections block, one for the map and one
for each layer. Consequently, it works with mapserver & without OL.
Regards.
Clement
