Hi all, I've been having some trouble reading text files in my game, the code I'm using works fine when run in the editor but when I export it I get this error: java.lang.RuntimeException - (JavaScript) ReferenceError: jl_NoClassDefFoundError And here is the code I use to load a file:

InputStream input = getClass().getResourceAsStream("levels/" + filename + ".txt");
Scanner reader = new Scanner(input);

Does anyone have experience reading from files after the switch to javascript/HTML5?

What possible values may be assigned to filename?

That's just the name of the file without the extension. I currently only have one level named test so it makes the path "levels/test.txt," and that path exists in the greenfoot project directory locally

Seems like you have everything in order. Maybe your file operations are not what javascript would allow.
