How to correctly get image from ‘Resources’ folder in NetBeans

by

This was a pain, using netBeans IDE 7.2.

  1. You need to remember that Netbeans cleans up the Build folder whenever you rebuild, so

  2. Add a resource folder to the src folder:

    • (project)
      • src
        • project package folder (contains .java files)
        • resources (whatever name you want)
        • images (optional subfolders)

  3. After the clean/build this structure is propogated into the Build folder:

    • (project)
      • build
        • classes
          • project package folder (contains generated .class files)
          • resources (your resources)
          • images (your optional subfolders)

To access the resources:

dlabel = new JLabel(new ImageIcon(getClass().getClassLoader().getResource("resources/images/logo.png")));

and:

if (common.readFile(getClass().getResourceAsStream("/resources/allwise.ini"), buf).equals("OK")) {

worked for me. Note that in one case there is a leading “https://stackoverflow.com/” and in the other there isn’t.
So the root of the path to the resources is the “classes” folder within the build folder.

Double click on the executable jar file in the dist folder. The path to the resources still works.
