if OL shows an image - although it is white - I guess you are on the wrong list.... For Mapserver an empty image could mean: - you are in the wrong extent (e.g. BBOX and EPSG in your getMap Request don't fit.) - there are no objects to be drawn, because you expressions might be wrong (-->test with EXPRESSION /./ in the first Class) I'm sure there are more possible reasons, but it might be worth checking these first. In Qgis - depending on the vesion - you'll have to adapt the standard ESPG number to the EPSG in which your WMS is able to serve.
