Question

I have created a GUI program that uses a class to perform some tasks.

I would like to add logging in both the JFrame and the class. Logs should be kept in a file and displayed in a JTextArea concurrently.

What is a convient solution for this?

Answer 1

Create a wrapper that

1. updates your JTextArea
2. logs via log4j, SLF4J or Apache Commons Logging or another logging framework

public void log(String msg) {
      appendToJTextArea(msg);
      LOG.info(msg);
 }
