argument ignored in jnlp file

Question

args.length is always 0.
public static void main(String[] args) {
if (args.length > 0) {
//Do something useful
Here's my jnlp file, with some names changed "to protect the innocent".

Answer 1

This suddenly started working when I got all-permissions to work. (That was a separate questions I posted on the same day.)
