OpenWFE relies heavily on the fine Log4j for logging.

Each component of the standalone OpenWFE release has its log4j configuration within its etc/ subdir. For example, the worklist has it in etc/worklist/logging.xml. The XML version of those configuration files are used.

By default, the standalone version of OpenWFE has its component logging level set to 'DEBUG'. Before passing an installation into production mode, one should take care of switching it to 'INFO' or even 'WARN' level. It will improve OpenWFE's performance and prevent logs from slowly filling up the available disk space (a log rotation tactic could come in handy here).

Each component of the standalone OpenWFE release produces log output within the logs/ directory. The engine, for example, logs into logs/engine.log.
