Usage

From source file:org.apache.cxf.common.logging.LogUtils.java

private static void doLog(Logger log, Level level, String msg, Throwable t) {
    LogRecord record = new LogRecord(level, msg);

    record.setLoggerName(log.getName());
    record.setResourceBundleName(log.getResourceBundleName());
    record.setResourceBundle(log.getResourceBundle());

    if (t != null) {
        record.setThrown(t);/*  w  ww .ja v a2 s  .  c  o m*/
    }

    //try to get the right class name/method name - just trace
    //back the stack till we get out of this class
    StackTraceElement stack[] = (new Throwable()).getStackTrace();
    String cname = LogUtils.class.getName();
    for (int x = 0; x < stack.length; x++) {
