I am using java.util.logging for logging (I don\'t want to use log4j or anything else).
This is my complete private logging.properties:
How do I figure out why FileHandler isn't using my LogFormatter class?
Start the program in a debugger and step through the code. Set a breakpoint in LogManager.getLogger() and/or LogManager.readConfiguration()
Or forget about java.util.logging and use a framework like logback that is easy to configure and gives you useful error messages when something is wrong.
