Then in conf/ (or in CATALINA_OPTS) set the system property openejb.log.factory to log4j2:


Then you’ll get the container logs redirected to log4j2.

But when it comes to CDI and since it was mainly designed for small apps it is hard to say “I have a CDI dependency/library”.

To make it easier we added @Jars recently.
