[olivier.terral]

oh it's mistake, too more test :)

I've cleanup my files now I 've a new error:

var mapOptions = {
                 controls:[],
               projection: "EPSG:54004",
               units: "m",
               maxExtent: new 
OpenLayers.Bounds(-19977777,-7481525,20037508,18356400),
               maxResolution:47524
           };
              
  map = new OpenLayers.Map($('mainMap'),mapOptions);

layer definition:

var layerOptions = {
                 visibility:true,
                 transparent:"TRUE",
                 projection:"EPSG:54004",
                 maxExtent: new 
OpenLayers.Bounds(-19977777,-7481525,20037508,18356400
),
                 maxResolution: 47524
      };
layer= new OpenLayers.Layer.WMS("ocean","http://localhost/wms-c",
               {
                   layers: "ocean",
                   transparent:"TRUE",
                   format:image/png,

               },
               layerOptions
           );

map.addLayers(layer);
