try {

Handler handler = new FileHandler("OutFile.log");
Logger.getLogger("").addHandler(handler);

} catch (IOException e) {

Logger logger = Logger.getLogger("package.name");
StackTraceElement elements[] = e.getStackTrace();
for (int i = 0, n = elements.length; i < n; i++) {

logger.log(Level.WARNING,
elements[i].getMethodName());
