[Kai Behncke]

Thank you very much, so now a


        var xyz = new OpenLayers.Control.GetFeature({
                protocol: OpenLayers.Protocol.WFS.fromWMSLayer(layer),
                hover: true,
                clickTolerance: 50    
       });


 xyz.events.register("hoverfeature", this, function(e) {
 var my_feature = new OpenLayers.Feature.Vector(e.feature.geometry,null, style_obj1);     
      hover.addFeatures([my_feature],null,{styleMap: style_obj1});
            });


....gives me what I wanted.  :-)

Best regards, Kai
