You can get file name and its extension in client side (in your gwt codes) using flowing code:

FileUpload fileUpload = new FileUpload();

Button uploadButton = new Button("Click");
uploadButton.addClickHandler(new ClickHandler() {
  public void onClick(ClickEvent event) {
    String filename = fileUpload.getFilename();
      Window.alert(filename);
  }
});
