I tried #1 below and it works sometimes. The key was setting the srsName. That was the whole trick. Are those options like 'typeName', 'srsName', etc. case sensitive?
Trouble is, my WFS layer only shows at small scales but not when zoomed in...what other things can I check. Is that a server side issue? David A. Hollema GIS Analyst United Power, Inc.

Jim 2009/4/8 David Hollema <[email protected]> Here is my code. WMS reprojects fine b/c my understanding is geoserver receives the base map projection (900913) and reprojects accordingly. I would figure that geoserver would do the same thing to the WFS but it doesn't. My SRS handling in geoserver is set to force declared (default setting) and my declared is correct, 2231 in this case. For WMS, it's not even necessary to set the srs in the layer constructor b/c geoserver just figures it out. It's important to note that I even tried with my source data in 4326 (lat/long) and WMS still worked fine but WFS fails. It doesn't seem to be due to State Plane issues but it's more fundamental than that. var bounds = new OpenLayers.Bounds (-20037508.34, -20037508.34, 20037508.34, 20037508.34); var options2 = { units: 'm', projection: 'EPSG:900913', maxExtent: bounds }; format = 'image/gif'; map2 = new OpenLayers.Map('map2', options2); velayer = new OpenLayers.Layer.VirtualEarth( "VE", { 'type': VEMapStyle.Roads, 'sphericalMercator': true}); layerWMS = new OpenLayers.Layer.WMS( "Joint Use Photos", "http://upigis:8080/geoserver/wms";, {layers: 'sde:jointusepicture', format: format, transparent: true }, {opacity: 1.0, isBaseLayer: false, 'singleTile': true }); layerWFS = new OpenLayers.Layer.WFS( "Joint Use Photos WFS", "http://upigis:8080/geoserver/wfs";, { typename: "sde:jointusepicture"}, {extractAttributes: true} ); David A.

You just have to add &srsName=EPSG:900913 to your request, keeping the eventual bbox in 2231, or have the bbox in 900913 too, but state it explicitly with &bbox=x0,y0,x1,y1,EPSG:900913 Cheers Andrea -- Andrea Aime OpenGeo - http://opengeo.org Expert service straight from the developers. _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users ------------------------------------------------------------------------ ------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
