Appenders in log4j

[xeon costa]

I've a java file that declares a class and an inner class. Both classes must log to distinct log files. 'A' class must log to A.log and 'B' must log to B.log. How can I set these classes to the respective appenders?

Below are the files:

package com.psc;

import org.apache.log4j.Logger;



public class A {
    private static final Logger LOG = Logger.getLogger(A.class);

    public void test() {
        LOG.info("TOMA1");
        B b = new B();
        b.test();
    }
    private static class B {
        private static final Logger LOG2 = Logger.getLogger(B.class);

        public void test() {
            LOG2.debug("TOMA2");
        }
    }

    public static void main(String[] args) {
        A a = new A();
        a.test();
    }
}

# Root logger option
log4j.rootLogger=INFO, stdout,A,B
 
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

# Direct log messages to a log file
log4j.appender.com.psc=org.apache.log4jFileAppender
log4j.appender.com.psc.File=a.log
log4j.appender.A.Threshold=INFO
log4j.appender.com.psc.layout=org.apache.log4j.PatternLayout
log4j.appender.com.psc.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

# Direct log messages to a log file
log4j.appender.B=org.apache.log4j.FileAppender
log4j.appender.B.File=b.log
log4j.appender.B.Threshold=DEBUG
log4j.appender.B.layout=org.apache.log4j.PatternLayout
log4j.appender.B.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

This question is too difficult for “beginning” and would fit better into a different forum, so I am moving it.
