I have a jar file with a log4j properties file included. I tried to use

-Dlog4j.configuration=file:[filename]

to change the properties file at runtime using java, and it didn't work. I need to do this in a sh file Can anyone please tell me how to this? I also tried adding

-Dlog4j.defaultInitOverride=true

It's possible to override the log4j properties file at runtime. You may fall into this situation if you cann't :

1. In your jar or somewhere in the code, the log4j system is initialised manually, e.g.

    URL url=loader.getResource(LOGGER_CONFIG_FILE)
    DOMConfigurator.configure(url);
