Use loggers in an application

 

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

 

Overview

To create an application using Java logging, perform the following steps:

 

Procedure

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

2. If localized messages are used by the application, create a resource bundle, as described in Creating log resource bundles and message files.

3. In the application code, get a reference to a logger instance, as described in Use a logger.

4. Insert the appropriate message and trace logging statements in the application, as described in Use a logger.
