Is it right that the procedure of using log4j looks like this:

1) put a .properties file somewhere in a project folder

2) in an initialization method, that runs only once, invoke

PropertyConfigurator.configure("path_to_file");

3) in every method we need to use logger we define a static logger variable and simply invoke getLogger(class)

I'm asking you this: what if the initialization module is not defined?

Where to put "log4j.properties" file so that we wouldn't need to invoke propertyconfigurator.configure at all, or if it's not possible,

is it ok to invoke PropertyConfigurator.configure("path_to_file") in every method that uses a logger?
