Mule ESB Log4j2 support

Question

Does Mule ESB support log4j2? I am trying to add log4j2.xml in my esb app, but even after adding log4j2.xml, my mule esb app is defaulting to its own log4j 1.2 implementation. I want my esb app to read my log4j2.xml file and take/consume in the parameters what I am specifying in my log4j2.xml and if log4j2.xml file is present then it should not read its own log4j 1.2 implementation log properties file.

I am having problem in implementing log4j2(.xml) with mule esb app. Any help would be very much appreciated.

Answer 1

The latest version of mule esb is supporting the log4j2 . Hope the version may be tightly coupled that could be the reason it might not work.

Answer 2

Log4j2 has an adapter allows application that are coded against the log4j-1.2 API to use the log4j2 implementation. (See also the FAQ.)

Steps to achieve this:

• remove the log4j-1.2.x.jar from the classpath
• add the log4j-1.2-api-2.0.jar jar to the classpath.
• ensure that log4j-api-2.0.jar and log4j-core-2.0.jar are in the classpath

Now both the log4j-1.2 API and the log4j2 API will delegate to the log4j2 implementation. A sample configuration is here.

Answer 3

Log4j2 is implicitly supported from Mule-3.6.0 onwards. For more info please go through this link Asynchronous Logging in Mule

Answer 4

Mule esb supports log4j. check if you have imported slf4j libraries.

You need to create/rename log4j2-test.xml

Answer 5

These are my log4j2.xml and my pom.xml files, I´m using mule v7.1. I hope it helps.
