Answer 1

import org.apache.log4j.PropertyConfigurator;

Import this, then:

Properties props = new Properties();
InputStream is = Main.class.getResourceAsStream("/log4j.properties");

try {
    props.load(is);
} catch (Exception e) {
    // ignore this exception
    log.error("Unable to load log4j properties file.",e);
}
PropertyConfigurator.configure(props);

My java files directory like this:

src/main/java/com/abc/xyz

And log4j directory like this:

src/main/resources
