Log Records

The Enterprise Server uses the Java EE platform Logging API specified 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
file named server.log and renames the old file server.log_date, where date is the date and
time when the file 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 configuration.
Log records follow a uniform format:
[#|yyyy-mm-ddThh:mm:ss.SSS-Z|Log Level|ProductName-Version|LoggerName|Key Value Pairs|Message|#]
For example:
1 7
165
