ADF logging

Beginner programmers tend to litter their code with System.out.println() calls because that's the print statement used in the ubiquitous "Hello World" examples. As programmers gain experience, they tire of having to remove all of these statements before putting code into production and start using a proper logging framework.

There are several options for logging in Java—some of the most well-known are log4j and Logback. However, in an ADF application, it is recommended to use the ADFLogger.

Note

The ADFLogger can write its log output in Oracle Diagnostics Logging (ODL) format that can be read and analyzed by both the developer (in JDeveloper) and by a WebLogic administrator (using Oracle Enterprise Manager Grid Control). If you are running your application in GlassFish, your operations people do not have grid control. However, since ADFLogger offers all necessary logging functionality, it makes sense to use this logging framework just in case your application will some day be deployed...
