FUSE Services Framework uses the Java logging utility, java.util.logging. Logging is configured in a logging configuration file that is written using the standard java.util.Properties format. To run logging on an application, you can specify logging programmatically or by defining a property at the command that points to the logging configuration file when you start the application.

FUSE Services Framework comes with a default logging.properties file, which is located in your InstallDir/etc directory. This file configures both the output destination for the log messages and the message level that is published. The default configuration sets the loggers to print message flagged with the WARNING level to the console. You can either use the default file without changing any of the configuration settings or you can change the configuration settings to suit your specific application.

FUSE Services Framework includes a logging feature that can be plugged into your client or your service to enable logging. Example 7.1 shows the configuration to enable the logging feature.
