Re-configure a particular logger:

private static final Logger LOGGER
  = Logger.getLogger(ClassName.class.getName());
static
{
  try
  {
    LOGGER.addHandler(new FileHandler("mylog.xml"));
    // if you don’t want additional console output:
    LOGGER.setUseParentHandlers(false);
  } catch(IOException ex)
  {
    throw new ExceptionInInitializerError(ex);
  }
}

Or change the global configuration:

  1. Create a properties file like this:

    handlers=java.util.logging.FileHandler
java.util.logging.FileHandler.pattern=mylog2.xml
# add more options if you like

  2. Run your application with -Djava.util.logging.config.file=<path to the file above>.

In either case:

Study http://docs.oracle.com/javase/7/docs/api/java/util/logging/LogManager.html and http://docs.oracle.com/javase/7/docs/technotes/guides/logging/overview.html

You may do that using Log4j or some library.

You can export as XML for example with http://logging.apache.org/chainsaw/

There must be something similar with HTML, have a look at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/HTMLLayout.html
