So did you:
"To integrate an alternate logging implementation, you would provide an implementation of the LoggerPlugin interface and specify that it should be used by setting the org.jboss.logging.Logger.pluginClass system property to implementation class name."
Do I didn't because I misinterpretted the meaning of "system property" the documentation refers to. After following your directions, I was able to replace the default logger with the null logger and assume it will be straightforward to create my custom logger.
Thanks for the help.
