Question

I’m writing an app in GWT (mapfaire.com) which uses the Google Maps API, and I’d like to use the utilities library. Writing a JSNI wrapper for the libraries isn’t a problem, but how do I ensure the compiler ‘bakes’ the JS into the app itself, rather than downloading them separately via a module script include?

In gwt 2.4 added ScriptInjector
http://gwt-code-reviews.appspot.com/1451818/

   ScriptInjector.fromUrl("http://example.com/foo.js").setCallback(
     new Callback<Void, Exception>() {
        public void onFailure(Exception reason) {
          Window.alert("Script load failed.");
        }
        public void onSuccess(Void result) {
          Window.alert("Script load success.");
        }
     }).inject();
