java getResource() not working

this is driving me crazy. I have a NetBeans project in a folder with the following structure:

MyProject
---- build
---- src
---- resources

in src my code is in packages. What I am trying to do is to use

getClass().getResource("/resources/new.png");

from a class in package com.my.package but it just refuses to work! The "new.png" image is in the resources folder. Am I missing something here?

After a lot of playing around and moving the "new.png" image here and there to see when it will find the image, it finally worked but only when I put the image in the build folder. So what do I have to do to make this work ?

edit: sorry, wrong String in method parameter. Corrected now

Solution

I'm not familiar with NetBeans, but the problem is probably that the resources folder (or the root of the project, for that matter) is not on the classpath, unlike build.

You need to configure NetBeans to add the root folder, or resources to the classpath, and load the file relative to there.
