I have an applet that uses 4 text files. I want to put it all together in a jar file and upload it to my site. But I'm having problems accessing the text files I've put inside the jar file. The error is a NullPointerException on the line:
InputStream dataStream = getClass().getResource(filename).openStream();
in the FlatFile.java class.

Can anyone suggest a solution for how to achieve what I want?
