A small set of classes to extend standard JRE's java.util.logging package with practical and real-life cases, and make it suitable for production and industrial use.


  • usable and already used in several real-world production setups, yet without any impacting bug found
  • optimized for space, speed and memory efficiency from the start on
  • configured using standard j.u.l. properties
  • barely documented with a sample properties file
  • ConsoleHandler allows separate stdout / stderr outputs depending on message level (allows coloring errors with red in IDE like Eclipse and such)
  • DailyRollingFileHandler is used to rotate and purge log files on a daily basis
  • CustomFormatter formats log records from a user-given template, including % fields like those of Log4J (but simplified) and on a single line by default


See downloads page.


  • XML based configuration, with formal grammar and checking
  • per-webapp configuration and log files in JavaEE environment
  • zip / gzip / deflate compression of daily log files
  • JDBC handler
  • Syslog handler
