All you need is a SINGLETON logger. You may google "singleton java" for
details.

The Logger class my like this

/**
* <p>Title: TODO Untitled Document </p>
* <p>Description: TODO No Description Specified </p>
* <p>Copyright: Copyright (c) 2005</p>
* <p>Company: ±±¾©¶«·½¹úÐŵç×ÓÓÐÏÞ¹«Ë¾</p>
* @author ÖܺìÑô
* @version 1.0
*/
public class Logger
{
   private static Logger self;

   //key word PRIVATE prevent to invoke this constructor
   private Logger()
   {
   }

   //use this static method to get a instance of  Logger
   public static Logger getInstance()
   {
       if (self == null)
           self = new Logger();
       return self;
   }

   //keyword "synchronized" make this method thread safe, only one thread
can invoke this method at one time
   public synchronized void debug(String msg)
   {
   }

   public synchronized void info(String msg)
   {
   }

   public synchronized void fatal(String msg)
   {
   }

}
