Is it possible to add or override log4j configuration previously loaded by log4j.xml file

  • 0

Is it possible to add or override log4j configuration previously loaded by log4j.xml file with another log4j.xml file loaded at runtime ?

My Glassfish server loads at startup log4j.xml file and I would like to change this configuration with another log4j.xml file in EAR file.

I tried to use DOMConfigurator.configure("log4j.xml") but it seems that the previously configuration is not overrided (but this method find log4j.xml file because when I change to non existing file, I have Exception).

How can I do this please ?

    A log4j Configurator always applies its configuration starting from the “current” settings. If you want the new settings to replace the old ones, simply call LogManager.resetConfiguration() first, before calling the DOMConfigurator.
