"URI is not hierarchical" when running JavaFX application on NetBeans

Question

I am getting this "URI is not hierarchical" error when I run a JavaFX application. The exception is thrown in line 4 of the code below. Do you know how could I fix this?

001          { // HISTORY
002              try {
003                  URI uri = MainClass.class.getResource("history.txt").toURI();
004                  File f = new File(uri);
005                  String text = FileUtils.readFileToString(f);
006                  historyTextArea.setText(text);
007              } catch (URISyntaxException | IOException ex) {
008                  Constants.LOGGER.log(Level.SEVERE, ex.toString());
009              }
010          }

.

The problem is that you have a URI that refers to a resource inside a JAR file. The File(URI) constructor cannot cope with a URI like that. It only understands URIs for files.

What you need to do is something like this:

    String text;
    try (InputStream is = MainClass.class.getResourceAsStream("history.txt")) (
        text = IOUtils.toString(is);
    } catch (...

Ah yes... you are right. It was working before, but I think I had that file outside the jar. Thanks!

Wonderful! This is my code now: <code> { // HISTORY try (InputStream inputStream = MainClass.class.getResourceAsStream("history.txt");) { String text = IOUtils.toString(inputStream); historyTextArea.setText(text); } catch (IOException ex) { Constants.LOGGER.log(Level.SEVERE, ex.toString()); } } </code>

For those wanting to load an FXML document included as a resource....

Parent page = new FXMLLoader().load(getClass().getResourceAsStream("/fxml/Gui.fxml"));

Your fxml cannot include a Stylesheet.
