Getting File from .jar using .getResource()

Question

I'm trying to acces a File inside the .jar. In Netbeans, this:

System.out.println(new File(this.getClass().getResource("Image.jpg").getFile()).exists());

Prints out:

true

After building however, it prints false.

The file is definitely in the .jar, next to the .class file, and something like this:

new Frame(){ @Override public void paint(Graphics g){ try{ g.drawImage(ImageIO.read(this.getClass().getResource("Image.jpg")), 0, 0, this); } catch(Exception e){e.printStackTrace();} } }.setVisible(true);

does paint the image after building.

How can I acces the Image.jpg as a File object?

The file is packed, try

resource.getInputStream()

or

InputStream streamOfYourImg = this.getClass().getRessourceAsStream("com/package/resources/image.jpeg");

Hope it helps

You don't get a File object to it. Its an entry in a JAR not a File on the Filesystem. You have a few options. Create a File by copying the InputStream to the Filesystem, FInd a way to use the InputStream instead, or always have your JAR expanded.
