[Solved] WARN No appenders could be found for logger

Posted Jan 31, 2013

log4j:WARN No appenders could be found for logger (com.turn.ttorrent.common.Torrent).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

If you are encountering the error above when you're running a program that uses log4j, the solution is to add a log4j.properties that can be seen by the class loader. Normally it's in the "src" folder of your Java project:

Here's an example of log4j.properties content:

log4j.rootLogger=INFO, stdout

log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
