Yes, you need to provide a complete capabilities url for the url parameter:
http://localhost:8080/geoserver/wms?SERVICE=WMS&REQUEST=GetCapabilities
Also note that if your GeoServer is on the same host as your
application (http://localhost:8080/ in this case), you can use
/geoesrver/wms?SERVICE=WMS&REQUEST=GetCapabilities
This will avoid cross domain scripting issues.
