It is very nice if

Answer 1

You can read files in your GWT app using RequestBuilder

new RequestBuilder(RequestBuilder.GET, "path/to/file.txt").sendRequest("", new RequestCallback() {
  @Override
  public void onResponseReceived(Request req, Response resp) {
    String text = resp.getText();
    // do stuff with the text
  }

  @Override
  public void onError(Request res, Throwable throwable) {
    // handle errors
  }
});

Answer 2

If the text file is part of your GWT project, you can include it in a ClientBundle. If it's not part of your project, then the RequestBuilder sounds like the right answer.

I posted a simple example project to show how to use a ClientBundle.

String greetings = Assets.INSTANCE.greetings().getText();
final Greeter greeter = new Greeter();
greeter.loadGreetings(Arrays.asList(greetings.split("\\n")));
