Help with Log4j

[Raj kumar]

How can I pass the error statements to a file and debug statements to the console using log4j?


Thanks

instantiate 2 loggers:

  
Logger logErrors = Logger.getLogger(YourClass.class);
Logger logDebugs = Logger.getLogger(YourClass.class);

and create appenders for each in log4j.properties:

  
log4j.logger.yourpackage.yourclass=ERROR, txt_errors
...
log4j.logger.yourpackage.yourclass=DEBUG, txt_debugs
...

n.b. txt_debugs will log everything of DEBUG priority and higher (including ERRORs), therefore messages may be duplicated.

BTW - this should probably be in "Other Open Source Projects".
