Log4j not working as expected with ejb module

[Arun Merum]

Hi, I have an EAR project where in I have to log all my servlet logs and EJB logs to two different files. I have a log4j.xml file packaged in the root directory of the .ear file. In other words the .ear file contains log4j.xml, log4j.jar, webModule.war and ejbModule.jar file. While the servlet log are getting logged as expected with the below log4j.xml file, EJB logs are completely being omittied from getiing logged to the firstEJB.log file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

If I add both the appenders to the <root> catagory the servlet logs get logged to firstS.log twice and once to firstE.log again missing the EJB logs altogether. I am not using any log managers in my code. Is it some initialization problem with the ejbMOdule or someing like that? Please help me in this regard. Thanks in advance.

How do you get hold of the logger in your EJBs? Post that piece of code (including the package declaration).

[Arun Merum]

Hi,

 org.apache.log4j.Logger.getLogger(FirstSessionBean.class);

is what I use in the EJB to get the logger. Thanks for the quick reply.

Like I said in my previous reply :

Which package does FirstSessionBean class belong?

[Arun Merum]

The EJB code

package org.mourya.one.sessionbeans;

import javax.ejb.*;
import org.apache.log4j.Logger;

@Stateless(name="FirstSessionBean")
public class FirstSessionBean implements FirstRemote {
	static Logger logger = Logger.getLogger(FirstSessionBean.class);
	public String getGreeting(String name){
		logger.warn("Called");
		return "Hello " + name;
	}
}

and the servlet code

package org;

import java.io.*;
import org.mourya.one.sessionbeans.*;
import javax.naming.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.log4j.Logger;

public class FirstServlet extends HttpServlet{
	static Logger logger = Logger.getLogger(FirstServlet.class);

	public void doGet(HttpServletRequest req,HttpServletResponse response) throws ServletException,IOException{
		logger.warn("doGet begin");
		response.setContentType("text/html");
		PrintWriter out = new PrintWriter(response.getWriter(),true);
		try{
			InitialContext ic = new InitialContext();
			FirstRemote fr = (FirstRemote)ic.lookup("ear-1.0/FirstSessionBean/remote");
			out.println(fr.getGreeting("Animal"));
		}catch(Exception e){
			logger.fatal("Fatal!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
			e.printStackTrace();
		}
		logger.warn("doGet end");
	}
}

Thank you.

Based on what you have posted I don't see anything wrong with the code or the config. I would expect the logs from the bean to be logged to the firstE.log and firstS.log files, assuming the bean method is being called.
