Logger from JDK SE 1.4.1 writes out messages not only to MY FileHandler but to stderr also. Note that I have manually deleted all FileHandlers: SQLlogger = Logger.getLogger("name"); FileHandler fh = null; Handler hs[] = SQLlogger.getHandlers(); for (int i=0; i SQLlogger.removeHandler(hs[i]); } fh = new FileHandler("filename", 1000000, 3); fh.setFormatter(new SimpleFormatter()); SQLlogger.addHandler(fh); // Request that every detail gets logged. SQLlogger.setLevel(Level.ALL);    More>>

			

			SQLlogger = Logger.getLogger("name");
			

			FileHandler fh = null;
			

			Handler hs[] = SQLlogger.getHandlers();
			

			for (int i=0; i
			

			SQLlogger.removeHandler(hs[i]);
			

			}
			

			

			fh = new FileHandler("filename", 1000000, 3);
			

			fh.setFormatter(new SimpleFormatter());
			

			SQLlogger.addHandler(fh);
			

			// Request that every detail gets logged.
			

			SQLlogger.setLevel(Level.ALL);
