Log4 appender not found

Question

I am making AXIS2 webservices and in that I have used Log4j. when running application it is giving error

 [java] log4j:WARN No appenders could be found for logger (org.apache.axis2.deployment.FileSystemConfigurator).
 log4j:WARN Please initialize the log4j system properly.

I have done following things

I have changed commons-logging property to use log4j ( as AXIS is using common logging )
To check if log4j.properties is in class path i have used resource bundle nad tried to a property from log4j.properties - which printed

Directory structure of my myapp.aar file is as below

How do I go forward from here, I am clueless please help me.

As suggested I run my app with -Dlog4j.debug=true but where can I find log4j log

@YeWin if you see image , you can see log4j property is in root directory where my source is. so it is in class path right? — Arvind, Nov 18 '16 at 11:24

There are another option to define the location of log4j configuration file in Axis 2 web service , is by using HttpServlet which excite at application startup and define the location of file to log4j . The require code listed below :

1.Define you servlet in web.xml

 <servlet>
    <servlet-name>log4j-init</servlet-name>
    <servlet-class>com.log.LogInit</servlet-class>
    <init-param>
        <param-name>app-log4j-file</param-name>
        <param-value>/WEB-INF/conf/log4j.properties</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

in this example the location of log4j.properties file is under WEB-INF->conf

1.Create LogInit class extends HttpServlet under com.log package

public class LogInit extends HttpServlet{
/**
 * 
 */
private static final long serialVersionUID = 1L;

public void init() {
    String path =  getServletContext().getRealPath("/");
    String fileName = getInitParameter("app-log4j-file");
    String strPathFile = path + fileName;
    if(strPathFile != null) {
      PropertyConfigurator.configure(strPathFile);
   }
}
}
