Question

The class example below MyAppender is called from the logback.xml file.

When the append() is called by logback i have no reference to the
class MyAppenderso i cannot attach any Observer or register a Listener

Does logback have some Listener the Swing gui can register or what should i do?

Have been reading the logback manual but i cannot figure this out.

public class MongoAppender extends AppenderBase<ILoggingEvent> {

  public MongoAppender () {
  }

  @Override
  public void start() {

    super.start();
  }

  public void append(ILoggingEvent event) {

    // Inserting log event into MongoDb
    // just got an error...
    // how do i send this error back to Swing Gui?
  }
}

Answer 1

In the append i did not make and call to the gui.
I ended up writing to the DB whatever needed to be saved.

This of course is cleaner and safer then having classes trying to
address each other.
