Accessing MDC data in Appenders?

[tm...@moneynet.com]

Everyone,

     Are MDC's associated or stored with LoggingEvents? I need to create a
custom appender and I was hoping I could do the following:

// Set some custom fields to log
MDC.put("user", "joe");
MDC.put("id", "123");

cat.debug("User info: ");


// In custom appender class..bogus code for now..just an example

append(LoggingEvent evt) {

     System.out.println("user: " + evt.getMDC().get("user"));
     System.out.println("id: " + evt.getMDC().get("id"));

}

Is this possible? Or do I have still have to create custom LoggingEvent
class that have the fields I want?

Thanks,
- Tim
