In case you want google maps in your gwt application you can use the
gwt-google-maps-v3 since gwt-google-apis is currently alpha.
You need to add the gwt-maps.jar on the build path but also you have to add the same jar at the WEB-INF/lib directory
And of course inside your module configuration file you need to add
<inherits name="com.google.maps.gwt.GoogleMaps" />
Then you are ready to go.
private GoogleMap placeMap;
private Marker placeMarker;
public void onModuleLoad() {
RootPanel rootPanel = RootPanel.get("main");
final MapOptions myOptions = MapOptions.create();
myOptions.setZoom(14.0);
myOptions.setMapTypeId(MapTypeId.ROADMAP);
LatLng myLatLng = LatLng.create(-34.397, 150.644);
myOptions.setCenter(myLatLng);
placeMap = GoogleMap.create(rootPanel.getElement(),myOptions);
}
