How to give relative path in java getResources()

Question

I am using eclipse juno for the java application and want to load an image on application and for that I am writing following code

 URL imageURL = LoginWindow.class.getClassLoader().getResource("resources/img/pause.png");

which gives the following error

Resource not found: resources/img/pause.png Exception in thread "main" java.lang.IllegalArgumentException: creating TrayIcon with null Image at java.awt.TrayIcon.(Unknown Source)

but if I put the image in the folder where my java file is and remove all path and give only "pause.png" then it works properly.

When using getResource, the path is relative to the class requesting it, if the path doesn't start with "/" — MadProgrammer, Apr 18 '14 at 05:09

The class loader that is obtained using that form of call would probably not be the context class loader intended for loading application resources. I would recommend instead:

LoginWindow lw = new LoginWindow();
// exactly as below, including leading /
URL url = lw.getClass().getResource("/resources/img/pause.png");

Get the Class Relative path from their you can refer to the the image

enter image description here

      ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
    String imgUrl =classLoader.getResource(".").getPath()+   
                                       "../resources/img/pause.png";

By using the imgUrl you do your what operation you want to do .

Give the structure of your project please. If you have a Maven project, your code should be as follows:

URL imageURL = LoginWindow.class.getClassLoader().getResource("src/main/resources/img/pause.png");

my resources is out side the src folder – Uday A. Navapara Apr 18 '14 at 04:49
This would still be false. Maven puts everything from `/src/main/resources` into the root of the classpath – Sotirios Delimanolis Apr 18 '14 at 04:53

try this if you are running in an applet

URL url = new URL(getCodeBase(), "resources/img/pause.png");

1) There is no indication this is an applet. In fact ` Exception in thread "main" ` suggests a frame based app. 2) The `getResource(..)` method works exactly the same for an applet as it does for an application. – Andrew Thompson Apr 18 '14 at 04:59
