Question

Answer 1

You might want to configure other defaults with a properties file. This allow things to be reconfigured without recompiling.

# Specify the handlers to create in the root logger
# (all loggers are children of the root logger)
# The following creates two handlers
handlers = java.util.logging.ConsoleHandler, java.util.logging.FileHandler

# Set the default logging level for the root logger
.level = ALL

# Set the default logging level for new ConsoleHandler instances
java.util.logging.ConsoleHandler.level = INFO

# Set the default logging level for new FileHandler instances
java.util.logging.FileHandler.level = ALL

# Set the default formatter for new ConsoleHandler instances
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

# Set the default logging level for the logger named com.mycompany
com.mycompany.level = ALL

I prefer this to littering my code with logging configuration calls.

You have to specify the location of the file with a command line option though :

java -Djava.util.logging.config.file=mylogging.properties 

I personally always use log4j or slf4j because it looks for a config file in the classpath. Well, maybe java.util.logging does that too, I never really investigated.
