RE: Log4J - transactions log
Log4j Version 1.2.14 here you are in the API
Logging package for printing log output to different local and remote destinations
I am using it, It's good, because it has differents levels of errors:
TRACE, DEBUG, ERROR, INFO etc. You always log, but depends on the defined level in the log4j.properties file the guy writes you in the log or doesn't
For example, we use TRACE, DEBUG, ERROR e INFO log levels in the tester environment; but in production just INFO.
they are differents log4j.properties files, so it´s to implements
