Hi Phil, For WMS you doesn't need to overwrite getFullRequestString(). You have to set projection in the layer options.
Look at http://osgeo-org.1560.x6.nabble.com/epsg-3857-and-google-900913-td5027619.ht ml Example http://gis.ibbeck.de/ginfo/apps/OLExamples/OL212/wms_options_projection.asp For OpenLayers the projections // list of equivalent codes for web mercator var mercator = ["EPSG:900913", "EPSG:3857", "EPSG:102113", "EPSG:102100"], are equal. If the layer projection equals the mapprojection, the layer projection are used.

April 2013 06:22 An: openlayers-users@lists.osgeo.org Betreff: [OpenLayers-Users] Having Google map api and arcGIS server. Anybetter ideas? ArcGIS Server doesnt like EPSG:900913 and maps doesnt like EPSG:3857. Its a pain. I got around this with a couple of overrides. Has anyone found a better way? Ext.override(OpenLayers.Layer.WMS, { getFullRequestString:function(newParams, altUrl) { var projectionCode = this.map.getProjection(); if((projectionCode == 'EPSG:900913') && this.url.search(/arcgis/)>=0) { this.params.SRS = 'EPSG:3857'; } else { this.params.SRS = (projectionCode == "none") ? null :projectionCode; } return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply( this, arguments); } }); Ext.override(OpenLayers.Request, { GET:function(config) { if((config.params.SRS == 'EPSG:900913') && config.url.search(/arcgis/)>=0) { config.params.SRS = 'EPSG:3857'; } config = OpenLayers.Util.extend(config, {method: "GET"}); return OpenLayers.Request.issue(config); } }); And for WFS protocol, create with: var srs = (currProj=='EPSG:900913' && source.serverUrl.search(/arcgis/)>=0) ? 'EPSG:3857' : currProj; if(spatialQueryNode.type=='wfs') { source.wfsProtocol = new OpenLayers.Protocol.WFS.v1_1_0({ url: spatialQueryNode.url, featurePrefix: spatialQueryNode.featurePrefix, featureType: spatialQueryNode.featureType, geometryName :geomName, srsName: srs }); -- Phil Scadden, Senior Scientist GNS Science Ltd 764 Cumberland St, Private Bag 1930, Dunedin, New Zealand Ph +64 3 4799663, fax +64 3 477 5232 Notice: This email and any attachments are confidential.
