Log4j2 error loading XML configuration file

I am trying to use the XML configuration file for Log4j2, which is built into my Java application, but does not work.

The code:

ConfigurationSource source = new ConfigurationSource(Main.class.getResourceAsStream("/in/gunbound/prelauncher/server/log4j2/log4j2.xml"));
ConfigurationFactory factory = (ConfigurationFactory) XMLConfigurationFactory.getInstance().getConfiguration(source);
ConfigurationFactory.setConfigurationFactory(factory);

Error:

An exception in the thread "main" java.lang.ClassCastException: org.apache.logging.log4j.core.config.XMLConfiguration cannot be added to org.apache.logging.log4j.core.config.ConfigurationFactory on in.gunbound.prelauncher. server.Main.main (Main.java:62)

When using an XML configuration file you do not need to use ConfigurationFactory. Just make sure your XML file is configured correctly.

The file name must be log4j2.xml

The file must be added to classPath.

( factory, URL-):

Configurator.initialize("configName", "logging.xml");

This works even if the configuration file is not named "log4j2. *".
