I created the docker and Kubernetes modules. Originally my employer used them
when sending data directly via TCP to a forwarder. However, we ran into
reliability issues with the forwarder when doing that so we switched to writing
to the console, despite benchmarks showing it is slower. But for
e modules.

The recommended approach is to do what Spring Boot does - build
a jar that has all its dependent jars in a directory. A jar is just a zip file
so you can either unzip it before running or have the start up program
set the classpath to the directory inside the zip. Of course, that may

In Log4j 1.2 a Category was the base class for a Logger. So this would simply
be
looking for all the Appenders attached to the Logger. If a Category/Logger has
no

You are in the correct place. You might also search StackOverflow if you
haven’t already.
We would need some more information on how things are configured and what you
have tried.
I don’t believe any of the committers use WebSphere but we have had other
questions recently.

In both of those log files Log4j is not seeing any value as being set of
log4j.configurationFile. It is ending up using the default configuration.

This is a problem. Log4j supports Lookups, which usually eliminate the need
to override things like setFile since you can create a custom lookup to do
whatever needs to be done.
Is there any chance you can post the code so we can figure out what it does?

1. We need to mark JsonLayout as deprecated. We no longer recommend using it.
Use JsonTemplateLayout instead.
2. The only consideration for JsonTemplateLayout is that you format the
template correctly.
FWIW, my employer has been using JsonTemplateLayout to log to ELK for quite a
while now
Personally, I wouldn’t recommend using PatternLayout to render JSON. There are
too many things that can go wrong and it is very limiting to do that.

The log4j-jul module is what maps anyone coding to java.util.logging to use
Log4j 2 as the recommendation. The log4j-to-jul module is used when Log4j 2 is
the API and java.util.logging is the implementation.
Note that log4j-to-jul is fairly new. It was introduced by LOG4J2-3282 in Jira
in Jan

I am not sure what question you are answering but it doesn’t look like the

There have only been 2 issues fixed since 2.19.0 was released 2 months ago. I
normally wouldn’t perform a release for so few non-critical changes after such

Note - the annotation processor will still be required in 3.0. Instead of
generating a Log4jplugins.dat file it generates a Java class file. That class
file is loaded via the ServliceLoader.

What you are running into is a fundamental difference in how Log4j 1.x worked

LogManager.getLogger(). Log4j 2.x does not do that. As Pier noted, this

You are correct that log4j-to-jul routes the log4j2 API to java.util.logging.
When using log4j-to-jul you cannot use ANY other log4j modules except for
log4j-api. You must configure Tomcat’s logging to handle all the logging for
your application.

I answered this same question on the dev list a week ago since you apparently

Your issue is related to you starting and stopping the LoggerContext while your
application is in an unknown state. I can think of a few ways to deal with
this.

One thing nobody else mentioned. Given that 3.x requires Java 17 you can be
assured that we will continue to support 2.x until Java 11s usage drops down
under 10% (or possibly lower) based on the usage surveys. This is the same
approach we have had with previous JDK versions. I would not expect
If you are creating separate LoggerContext’s then every one of them can have
its own configuration. The LoggerContext has an externalMap that you can add
items to. You could then create a Lookup to retrieve elements from the external
Map to resolve references in a common configuration file
