Where should a logger(log4j) be initialized in a servlet?

Question

I am initializing the logger in servlet's constructor. Is it a good practice? Should I rather initialize it in a servletContextListener?

Sample Code:

public class MyService{
Logger logger;

 public MyService(){
   logger = Logger.getLogger(MyService.class);
 }

}

Answer 1

Use the logger as a Class level member by declaring it as static

Initialize it properly

Little How-to

private static final Logger logger = Logger.getLogger(*<yourclass>*.class)

Answer 2

I think you're talking about initializing the log4j logging system, not a specific logger.

Use servletContextListener is better than the servlet's constructor.
