Answer 1

I supose you dont need to process that data in javascript, do you?

If you just want to download the file or display it in the browser, create a button in your page so as when the user clicks it will show in a new window or the user will asked to save the file:

final String url = "http://gwtquery.googlecode.com/git/README.txt";
String name = "README.txt";

Anchor link1 = new Anchor(name);
RootPanel.get().add(link1);
link1.addClickHandler(new ClickHandler() {
  public void onClick(ClickEvent event) {
    Window.open(url, "_blank", "");
  }
});
