Hi, I would start with the Geoserver demo layers and with complete WMS GetMap requests. Especially I recommend to always use SERVICE and VERSION with OGC web services even they are not always compulsory by the standard.
OpenJUMP comes with a nice BeanShell tool which shows the GetMap url that was used for fetching the image on the map. Here are examples for the "states" layer and for WMS 1.1.1 and 1.3.0 http://localhost:8080/geoserver/wms? SERVICE=WMS& REQUEST=GetMap& SERVICE=WMS& VERSION=1.1.1& WIDTH=459& HEIGHT=353& LAYERS=topp:states& TRANSPARENT=TRUE& FORMAT=image/png& BBOX=-125.964082115,14.004707960577342,-65.737188885,60.32299403942266& SRS=EPSG:4326& STYLES= http://localhost:8080/geoserver/ows? SERVICE=WMS& REQUEST=GetMap& SERVICE=WMS& VERSION=1.3.0& WIDTH=459& HEIGHT=353& LAYERS=topp:states& TRANSPARENT=TRUE& FORMAT=image/png& BBOX=14.004707960577342,-125.964082115,60.32299403942266,-65.737188885& CRS=EPSG:4326& STYLES= Pay attention to the order of lat and lon in the BBOX when using the EPSG:4326 system. ________________________________ Ryan Moody wrote: > Hello, > I have a WFS set up which is successfully returning me feature data in the > GML 3.1 format.
