The above SLD when added as a style to one of the layers in GeoServer 2.7.2 and published as a wms, is not able to display the labels(state names). In SLD, only the states are categorized and names have been given to them. Can someone please help me on this.
The SLD does not contain any TextSymbolizer, so there is no way it can display labels. If you have labels configured, you should report the lack of a TextSymbolizer as a bug in QGis
