public class LogLog extends Object
Logs statements from within Log4j.Log4j components cannot make Log4j logging calls. However, it is sometimes useful for the user to learn about what Log4j is doing. You can enable Log4j internal logging by defining the log4j.configDebug variable.
All Log4j internal debug calls go to
System.out
where as internal error messages are sent toSystem.err
. All internal messages are prepended with the string "log4j: ".- Since:
- 0.8.2
