JavaFX, getting resources of inside your JAR

br flagTradução: há uma versão em Português desse artigo.

For some classes like javafx.scene.image.Image is easy load an image from a external resource like:

ImageView {
    image: Image {
        url: ""

or a resource inside your own Jar file with the __DIR__ constant:

ImageView {
    image: Image {
        url: "{__DIR__}/myPicture.png"

But for other classes loading a internal resource (inside your own jarfile) is not so direct. For example, in the article Parsing a XML Sandwich with JavaFX I had to place the XML file in a temp directory. A more elegant way would be:

package handlexml;
import javafx.ext.swing.*;
import javafx.scene.Scene;
import javafx.stage.Stage;
class Resource{
    function getUrl(name:String){
        return this.getClass().getResource(name);
    function getStream(name:String){
        return this.getClass().getResourceAsStream(name);
var list = SwingList { width: 600, height: 300}
var myparser = PullParser {
    documentType: PullParser.XML;
    onEvent: function (e: Event) {
        var item = SwingListItem {text: "event {e}"};
        insert item into list.items;
    input: Resource{}.getStream("my.xml");
Stage {
    title: "Map"
    scene: Scene {
        content: list

With a simple XML file called my.xml inside your package.

<?xml version="1.0" encoding="UTF-8"?>
<bread sesame="true">
   <cheese type="chedar"/>


And we get the same result as before, but all files inside our Jars.
