Tom Smith commented on LOG4J2-303:
----------------------------------
Sorry for the confusion. A text area writer is just a java.io.Writer subclass
we have written with a TextArea that is used to display text. The TextArea is
not important.
This is what I can do in Log4j 1.2 and not in Log4j2---I append a subclass of
java.io.Writer to the logger. Key points are in bold
import java.io.Writer;
final Writer taw = new Writer();// you can't actually do this-Writer is
abstract, so I use a subclass in the real code.
final WriterAppender wa = new WriterAppender(new
PatternLayout(simplePattern), taw);
final org.apache.log4j.Logger theLog =
org.apache.log4j.Logger.getLogger("com.dd");
theLog.addAppender(wa);
Done!
This is a nice simple way to add a non-file, non-console appender to a logger.
Can't do that in Log4j2
Best,
Tom

> Reporter: Tom Smith

> I have an app that uses a log4J 1.2 style WriterAppender to write to a JavaFX
> window that so it can display the output in various ways (console, table
> etc). I can't get the same functionality with Log4j2-- Is this a deliberate
> oversight because of the xml configuration system?
