Hi, I am trying to draw a geodesic polyline with Google Maps JavaScript API from two address points.

<script type="text/javascript">// <![CDATA[

var polyOptions = {geodesic:true};
var polyline = new GPolyline([
  new GLatLng(),
  new GLatLng()
  ], "#f36c25", 5, 0.8, polyOptions);
map.addOverlay(polyline);
  if (GBrowserIsCompatible()) {
        map.addOverlay(polyline);
  }
// ]]></script>

Could someone tell me how can I dynamically geocode an address into GLatLng coordinates? (I am a little confused after reading Google's API documentation http://code.google.com/apis/maps/documentation/javascript/v2/services.html)

Thanks :)
