Tom Smith commented on LOG4J2-303:
----------------------------------


Pinning together some snippets, this is what I want to do:

       
        final TextAreaWriter taw = new TextAreaWriter(ta);   // taw extends 
java.io.Writer and knows how to display text in JavaFX output windows.

        final WriterAppender wa =
                new WriterAppender(new PatternLayout(simplePattern), taw);
        final org.apache.log4j.Logger ddlog = 
org.apache.log4j.Logger.getLogger("com.dd");
        ddlog.addAppender(wa);


It seems that this is not possible in Log4j2.


You can write to a file or stdout but not to a Writer.  Or not without some 
serious conniptions I think.

Thanks,
Tom

> 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?
