How do I use Log4j?

Camel uses sfl4j which allows you to configure logging via, among others:

The quick way to enable Log4j is to add log4j to your classpath or maven pom.xml. For example the following in your pom.xml should do the trick:

  <dependencies>
    <dependency>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
    </dependency>
    <dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
    </dependency>
  </dependencies>

Then to configure log4j you need to add a log4j.properties or log4j.xml to your classpath (so they go in a directory which is on your classpath).

Here’s an example log4j.properties file:

log4j.rootLogger=INFO, out

#
# uncomment the following line to enable debugging of Camel
#
#log4j.logger.org.apache.camel=DEBUG

log4j.appender.out=org.apache.log4j.ConsoleAppender
log4j.appender.out.layout=org.apache.log4j.PatternLayout
log4j.appender.out.layout.ConversionPattern=[%30.30t] %-30.30c{1} %-5p %m%n
#log4j.appender.out.layout.ConversionPattern=%d [%-15.15t] %-5p %-30.30c{1} - %m%n
