Answer 1

Can't really tell what you mean by not working without any log or explanation. Here are some possible reason:

1. cannot reach server at url http://localhost:8081/geoserver/NFR-SR/wms
2. layer name NFR-SR:Ridgeline_SR not found
3. map service doesn't support application/openlayers
4. It could even be it is working but you are viewing the map extent which does not contain any data.
