Google Maps and KMZ files

Does anyone know how to get Coldfusion to display a KMZ layer on a google map? I have a google map that has multiple layers and it works great but we would like the map to display a KMZ file as a layer. The KMZ file is located on the root of the web directory.

        map1.setCenter(new GLatLng(31.970804,-86.682129), 4);
  map1.setMapType(G_HYBRID_MAP);
  map1.setUIToDefault();

// Create a base icon for all of our markers that specifies the
        // shadow, icon dimensions, etc.
        var baseIcon = new GIcon(G_DEFAULT_ICON);
        baseIcon.shadow = "http://www.google.com/mapfiles/shadow50.png";
        baseIcon.iconSize = new GSize(20, 34);
        baseIcon.shadowSize = new GSize(37, 34);
        baseIcon.iconAnchor = new GPoint(9, 34);
        baseIcon.infoWindowAnchor = new GPoint(9, 2);

        // Creates a marker whose info window displays the letter corresponding
        // to the given index.
        function createMarker(point, title, contact, icao, iwwc, letter) {
          // Create a lettered icon for this point using our icon class
          var letteredIcon = new GIcon(baseIcon);
          letteredIcon.image = "http://www.google.com/mapfiles/marker"+letter+".png";

          // Set up our GMarkerOptions object
          markerOptions = { icon:letteredIcon, title:title };
          var marker = new GMarker(point, markerOptions);

          GEvent.addListener(marker, "click", function() {
            marker.openInfoWindowHtml("<u><b>" + title + "</b></u><br /><b>Phone:&nbsp</b>" + contact + "<br /><b>ICAO:&nbsp</b>" + icao + "&nbsp&nbsp&nbsp&nbsp&nbsp<B>IWWC:&nbsp</b>"+iwwc);
          });
          return marker;
        }

map1.addOverlay(createMarker(new GLatLng(41.939,-72.688), "Bradley International Airport", "DSN 220-2312", "KBDL", "CT3", "A"));
