loading multiple log4j properties

Hi,

I need to load three log4j.properties files.
say log4j1.properties, log4j2.properties, log4j3.properties
which will be used by different classes
MyLogger1.java, MyLogger2.java, MyLogger3.java

How do i do that? does second log4j overrides first one?

Thanks

Try

Properties combinedProps = new Properties();

// load all these separately: log4j1.properties, log4j2.properties, combinedProps.putAll(log4j1Props);
combinedProps.putAll(log4j2Props);
combinedProps.putAll(log4j3Props);

PropertyConfigurator.configure(combinedProps);

I will be loading it at different time and places, so how can it be managed.
I have no control on other log4j.properties as it it managed by someone else.

Are you trying to say that you want to load different log4j.properties file on the application? log4j.properties file is loaded at the class level and hence there would be only one log4j.properties file effective at a given time. But, if you want to load multiple log4j.properties, you need to use classloaders.

Instead of doing it that way - using multiple properties file, you should use log4j the way ithas been intended.
You should create just one file with different loggers as required. (And by this I dont mean just combining the files - design andconstruct the file as needed - for each logger)
There is nothing that you cant do with a single props file for which you would need multiple files.

No quite sure what you mean by that

You don't need control - you just need to be able to read the files
