I'm trying to redirect log4j output to a textarea but this one get filled at the end of the action since I'm using Platform.runLater
Is there any way I can do it with a different thread ?

AppFX.java

public class AppFX extends Application {





public static void main(String args) {

    ConfHandler.initConf();

    launch(args);

}



@Override

public void start(Stage primaryStage)throws IOException {

    primaryStage.getIcons().add(new Image("file:src/main/resources/images/frameIcon.png"));

    FXMLLoader loader = new FXMLLoader();

    String currentPath = System.getProperty("user.dir");

    loader.setLocation(new URL("file:\"+currentPath+"\src\main\resources\scenes\TestsFrame.fxml"));

    Parent content = loader.load();

    primaryStage.setTitle("IGED Tests");

    Scene scene = new Scene(content);

    primaryStage.setScene(scene);

    primaryStage.show();

    TextAreaAppender.setTextArea(((EaaSCleanerController)loader.getController()).getLogTextArea());

}}

TextAreaAppender.java

public class TextAreaAppender extends WriterAppender {

private static volatile TextArea textArea = null;



public static void setTextArea(final TextArea textArea) {

    TextAreaAppender.textArea = textArea;

}



@Override

public void append(final LoggingEvent loggingEvent) {

    final String message = this.layout.format(loggingEvent);

    try {

        Platform.runLater(new Runnable() {

            @Override

            public void run() {

                try {

                    if (textArea != null) {

                        if (textArea.getText().length() == 0) {

                            textArea.setText(message);

                        } else {

                            textArea.selectEnd();

                            textArea.insertText(textArea.getText().length(), message);

                        }

                    }

                } catch (final Throwable t) {

                    System.out.println("Unable to append log to textarea:" + t.getMessage());

                }

            }

        });

    } catch (final IllegalStateException e) {

    }

}}

log4j.properties

# Append the logs to the GUI

log4j.appender.gui=com.bp.nest.testauto.gui.TextAreaAppender

log4j.appender.gui.layout=org.apache.log4j.PatternLayout

log4j.appender.gui.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p - %m%n

You should put your actions on a separate thread. Then the logging can happen in parallel to your actions. You should never block the GUI-thread.
