Log4j2 - configuring

I am trying to adopt Log4j2 in my new project, but I get my logs in

catalina.out
, and the first one is always:
ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogger
. It seems that I have done everything according to Log4j2 docs, but still.

Here is what I have actually done:


  1. added
    log4j-api-2.0-beta3.jar
    to my project

  2. created a
    log4j2.xml
    file and put it in a location that is on the classpath (currently, in
    /usr/local/tomcat/home/lib
    . In fact, I took a sample file from Log4J2 web-page.

  3. restarted tomcat.



I am using Tomcat 7, MacOS X 10.8, Java 7.

What am I missing?

Just in case, here is the log4j2.xml I am using:


<?xml version="1.0" encoding="UTF-8"?>
<configuration status="warn" name="MyApp" packages="">
<appenders>
<File name="MyFile" fileName="logs/app.log">
<PatternLayout>
<pattern>%d %p %C{1.} [%t] %m%n</pattern>
</PatternLayout>
</File>
</appenders>
<loggers>
<root level="trace">
<appender-ref ref="MyFile"/>
</root>
</loggers>
</configuration>

Answer

I had the same problem. After adding also log4j-core-2.0-beta3.jar to the classpath it worked.
