Is your web page being served up on port 8008 (from localhost and via http)?
If not, you'll need to read up on the same origin policy.
Three alternatives (if this is your issue):
1) Get your WFS on port 80
http://geoserver.org/display/GEOSDOC/How+to+proxy+Jetty+through+Apache+on+port+80
2) Set OpenLayers.ProxyHost to something that can proxy for you
http://faq.openlayers.org/proxyhost/
3) Have your page served up on port 8080 (you can dump stuff in the www
dir in your geoserver config dir - not recommended for production).
If this is not your issue, disregard these suggestions.
