Apart from the missing leading `/`, can you post a directory structure of your application? Please make a [mcve]. – Tunaki Sep 27 '16 at 15:48

3Folders don't exist in jar files. You can't list folders inside a jar. – bmargulies Sep 27 '16 at 15:48

Add listing of contents of jar file to question. – Thorbjørn Ravn Andersen Sep 27 '16 at 15:48

You're telling the Class Loader to locate the file (resource) in "/folderName" which is the root (absolute). While "folderName" is the current folder (relative to) your class is located in.
Plus:
getClass().getResourceAsStream()is using the System Class Loader. Not the class loader that loaded the parent class.Use
Example.class.getResourceAsStream()and you should be able to access the resources.- Also if you're obfuscating the JAR you can't use a static path.
