Hello Steven, unfortunately I have no experience with geoserver, but request URLs from Openlayers WMS are conform to the OGC standards and if geoserver is also conform there should'nt be a problem. A OL generated request from my application:
http://www.gis-hosting.lu/ogc/service/osm?LAYERS=label&STYLES=,,,&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A2169&BBOX=67416.666666,70311.458332975,88583.333334,81688.541667025&WIDTH=1200&HEIGHT=645 It is in the Net tab from firebug. Something like GET osm?LAYERS= ... If you suspect the problem with geoserver you could try the WMS requests in your browser so you can be sure that they are working. If you think its a OL configuration problem please show your layer config code so that we can search there ... A OL WMS Layer example: new OpenLayers.Layer.WMS( 'WMS', 'http://www.gis-hosting.lu/ogc/service/osm', { layers: ['base','traffic','place-label'], styles: ['','','',''], format: 'image/png' }, { isBaseLayer: true, singleTile: true } ); Frank Am 23.04.2010 14:11, schrieb Steven Venter: > Hi Frank > > Thanks for replying. > > I used firebug to look at the requests being sent to the server.
