Using FileInputStream with a relative location not working with JAR

[bert de blonde]

Ok, so somewhere in my rickroll application i've got a file which is rickroll.mp3 and is the argument for a fileinputstream.

Now when i test my application in eclipse everything works fine. But when i export my source to a executable jar with eclipse the sound seems to be not loaded.

I'm also using JLayer to play the mp3 file but that shouldn't matter really.

So the problem here i think is that the path when compiled doesn't really point to my file anymore.
When i check back the jar file i created, all files (images/sound) needed are there.



Here is a pic of my project



And the jar file itself



And here is the failing code in my MP3.java at line 3-4

public void play() {
		try {
			FileInputStream fis = new FileInputStream(
					MP3.class.getResource("rickroll.mp3").getPath());
			BufferedInputStream bis = new BufferedInputStream(fis);
			player = new Player(bis);
		} catch (Exception e) {
			System.out.println("Problem playing file " + filename);
			System.out.println(e);
		}

		// run in new thread to play in background
		new Thread() {
			public void run() {
				try {
					player.play();
				} catch (Exception e) {
					System.out.println(e);
				}
			}
		}.start();

	}

I hope someone can help me out with what im doing wrong with the FileInputStream

But what you showed us is a picture of something in your IDE. Whereas what you should be looking at is the directory structure in the JAR.

On request i took a picture of the Jar file with 7-zip

I just noticed your code tries to use a FileInputStream. That doesn't make sense because the entry in the JAR isn't a file. Your relative URL is correct, just change from using getResource() to getResourceAsStream() and use the InputStream you get from that.
