Log Records
The Enterprise Server uses the Java EE platform Logging API specied in JSR 047. Enterprise
Server logging messages are recorded in the server log, normally found at
domain-dir/logs/server.log. When a log is rotated, Enterprise Server creates a new, empty
le named server.log and renames the old le server.log_date, where date is the date and
time when the le was rotated.
The components of the Enterprise Server generate logging output. Application components can
also generate logging output.
Application components may use the Apache Commons Logging Library to log messages. The
platform standard JSR 047 API, however, is recommended for better log conguration.
Log records follow a uniform format:
[#|yyyy-mm-ddThh:mm:ss.SSS-Z|Log Level|ProductName-Version | LoggerName|Key Value Pairs|Message|#]
