I have 1 package that manages the main JFrame of my application.
This JFrame needs to access an image (which is a resource) of another package.
I was able to get it to work using:
new ImageIcon(getClass().getResource("../"+packageName+"/icon.jpg"));But this does not work when using a runnable jar (getClass().getResource("../"+packageName+"/icon.jpg")) returns null). Any suggestions?
Are you saying that when you put the application in a jar file , the image is not found ? I am not sure but I think this article might help you :

I know all that already, but it doesn't explain how I can get the image from a different package in the same project...
getClass().getResource(...)
package OtherApp:
icon.jpg
package MainFrame:
MainApp - needs icon.jpg
You would think
getClass().getResource("../OtherApp/icon.jpg") would work.
It does, but not when using a runnable jar.
Has the directory structure of the packages been modified after the files have been added to a JAR? You will need to modify the
getClass().getResource("../OtherApp/icon.jpg")statement to reflect this modification. Also, did you read the section regarding URL's in that link I sent you just below
Accessing resources in a JAR.
