Java Web Start and JDK Logger

Question

The JDK logger uses the logging.properties file in the JRE lib directory. However I would like to use my own logging.properties file as part of the application that uses Java Web Start. This config file will be part of the application jar file.
The usual way to specify the logging properties file is by using the -D parameter
-Djava.util.logging.config.file=logging.properties
How do I specify my own logging.properties file for Java Web Start? TIA.

I'm trying to track down a solution to that problem too. The reason is because of the strange way webstart is creating its own log. It attaches a class: com.sun.deploy.util.LoggerTraceListener which records console messages. The way it does this is by generating its own log messages at the FINE level. If you look in the javaws.log file which is inside of the webstart cache area, you can see the result of this. On a mac this is located at: ~/Libraries/Caches/java/log
So if the console handler is configured to printing out FINE level messages then an infinite recursion happens. If you change the console handler's level so it isn't printing FINE messages then it works. But I want to see my own FINE level messages, so that isn't a good solution for me.
I tried setting com.sun.deploy.level=INFO in the global logging.properties, so webstart's log messages would not show up in the console. However, it appears webstart resets this level on startup.
If you set that property using the resource loading you figured out above, it might work because that should happen after webstart does its own logging configuration.
