I guess your vectors are in EPSG:4326. The OSGeo WMS layer is also in EPSG:4326, so the vectors display correctly onto this layer. > > IF I use this instead: > var layer = new OpenLayers.Layer.OSM(); > map.addLayer(layer); > > only one point feature is shown on the map and the text font has bad > quality. The OSM layer's projection is EPSG:900913 (Spherical Mercator)... Try adding projection:"EPSG:4326" in your vector layer options, to tell OpenLayers to transform the vector coords from EPSG:4326 to the map projection, that is EPSG:900913. This will only work if you use a BBOX or Fixed strategy in your vector layer. If not please show how you create the vector layer and add features to it.
