In the previous recipe, you created WMS and WFS from a PostGIS layer using MapServer. In this recipe, you will do it using another popular open source web-mapping engine-GeoServer. You will then use the created services as you did with MapServer, testing their exposed requests, first using a browser and then the QGIS desktop tool (you can do this with other software, such as uDig, gvSIG, OpenJUMP GIS, and ArcGIS Desktop).
