It looks like that Webstart will only be able to accept _some_ System
properties from the jnlp file. I think this is a security restriction.
>From what I can determine, I would suggest the _first_ line in the main
method of your webstart client is to set this system property, ie:
public static void main(String[] args){
System.setProperty("log4j.defaultInitOverride", "true");
....
Make sure this is the first line that gets executed, and there is no Logger
accessed in a static way inside your main class, (otherwise the static
reference to Logger will kick off the default auto initialization).
I hope that helps.
