And java file has

package test;

import org.apache.log4j.Logger;

public class testlog {

public static void main(String[] args) {
// TODO Auto-generated method stub
Logger APP_LOGS = Logger.getLogger("devpinoyLogger");
APP_LOGS.debug("start");
//applog1.debug("exec");
//applog1.debug("end");

}

}

log4j:WARN Please initialize the log4j system properly.
