+[tobyr] Hi Bill,
We include both logging files due to the implementation of Datanucleus. If you have log4j on your classpath (or if you have any jars which bundle the log4j classes), then Datanucleus will use the log4j logging system. If you don't have a configuration file for log4j, then none of the information will be displayed. That is why we include one by default. If you do not have log4j on your classpath, then the log4j system is not used, and neither is the log4j.properties file which we include. If you are sure that you do not have any log4j classes on your classpath, then you can safely remove the log4j.properties file, and control all of your logging via the logging.properties file. If you're using log4j, you can get rid of the logging.properties file. My recommendation would be to keep both files, and only update the one for the logging system that you're using. You don't need to keep both of them in sync unless you adjust the Datanucleus logging levels. Let me know if you have any questions - I know that this is somewhat confusing.
