I'm trying to add an AGS v10 layer to an OL map but it only seems to work if: - map.projection = WGS84 - map.displayProjection = WGS84 - isBaseLayer = true My end goal is to use Bing or ESRI cloud-based maps in EPSG:900913 as the base maps, so my map.projection will be EPSG:900913 and my map.displayProjection will be EPSG:4326. But the only way I can get AGS v10 REST and WMS services to display in an OL map is to set the map.projection, map.displayProjection and layer.projection to EPSG:4326. I'm using OL v2.11. I have AGS v10 services published as both REST and WMS. The CRS of the REST service is '102100 (3857)'. EPSG doesn't recognize 102100 which I believe is ESRI's own designation, so I experimented using 3857. If I view the service in an ESRI client (ArcMap, ArcCatalog) then it displays with the correct projection. But the only way I can display the layer at all in an OL map, whether using a OpenLayers.Layer.ArcGIS93Rest or a OpenLayers.Layer.WMS layer, is to use 4326 for both map.projection and map.displayProjection, which of course will not overlay on top of the Bing/ESRI base layers in EPSG:90013. While I'd prefer to be able to use WMS, any workaround would be acceptable. I wasn't able to get WFS to display at all, but that may be because I don't have all the OL layer params that are required. I tried:
var layer = new OpenLayers.Layer.WFS(
"Counties",
"http://myserver/arcgis/services/county_wm/MapServer/WFSServer?",
{ layers: "0" }
);
I found this information as well and tried that solution using a map.projection of 3857 for map.projection, map.displayProjection and layer.projection, e.g.:
var options =
{
'units': 'm'
};
var map = new OpenLayers.Map('gxmap', options);
mapprj = new OpenLayers.Projection("EPSG:3857");
dspprj = new OpenLayers.Projection("EPSG:3857");
map.projection = mapprj;
map.displayProjection = dspprj;
var layer = new OpenLayers.Layer.WMS(
"Counties",
"http://myserver/arcgis/services/county_wm/MapServer/WMSServer?",
{
layers: "0",
format: 'image/png',
srs: 'EPSG:3857'
},
{
opacity: 0.5,
singleTile: false,
projection: 'EPSG:3857'
}
);
but still no go. My WMS capabilities file for this layer looks thus:

Have also tried using 'crs' for layer instead of 'srs' per this thread, but still no go. Also worried that the 'isBaseLayer=true' will be required even if I do figure out the projection issue, since I need to display these as overlays. Has anyone been able to get a non-WGS84 ArcGIS v10 layer -- either REST or WMS -- to display in an OL map?
