Tiled Layer - NullPointerException

Question

Hi, getting a small problem when initialising a tiled layer object. When I initialise the TiledLayer object "backgroundLayer", it throws a NullPointerException, and the Catch "System.out.println("")" is also being displayed, stating it cannot find the image. The image itself is in the "src" folder for the game, it's a 31 by 61 PNG file named "levelOne.png". I can't figure out why the image isn't being displayed, please help lol.
Thanks.

If you're using NetBeans, the path of the image file should be relative to the project root. If as you say the image file is in the "src" folder that should bebackgroundImage = Image.createImage("/src/levelOne.png");Other IDEs may treat the path differently.
