This page describes how to use Java logging within an application.

To create an application using Java logging...

 

1. Create the necessary handler, formatter, and filter classes if we need our own log files.

2. If localized messages are used by the application, create a resource bundle

3. In the application code, get a reference to a logger instance.

4. Insert the appropriate message and trace logging statements in the application.
