The snippet you shared tries to add your custom appender to an already initialized logger context. Do you really need to add your appender after initialization and programmatically? If not, you can simply use your appender in `log4j2.xml` given you have its class in a package scanned by Log4j. You can use the `packages` attribute of the `Configuration` root XML element to provide the list of packages Log4j should look for custom plugins. See https://logging.apache.org/log4j/2.x/manual/configuration.html page for further details.
If you really need to this programmatically, you better use the `ConfigurationBuilder`: https://logging.apache.org/log4j/2.x/manual/customconfig.html On Fri, Oct 21, 2022 at 11:09 AM Thomas Hartwig <thomas.hart...@gmail.com> wrote: > > I want to add a customized Appender to Log4J 2.x.
