e403. Configuring Logger Default Values with a Properties File

The default values for loggers and handlers can be set using a properties file. This example demonstrates a sample logging properties file.

For more information about logging properties, see the lib/logging.properties file in the JRE directory.

    # 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
The custom logging properties file is loaded by specifying a system property on the command line:
    java -Djava.util.logging.config.file=mylogging.properties <class>
