如何关闭此日志记录？

Question

How do I turn off this logging?

-Djava.util.logging.config.file=file:lib/logging.properties

If I put -Djava.util.logging.config.file=file:lib/logging.properties in VM argument properties, then NOTHING will log!

I think that you will find that DataNucleus JDO (if indeed you are using JDO) depends on the logging technology Apache Log4J.

I use JDO and define DataNucleus Log4J settings in files called "log4j.properties": one for production and one for app building using NetBeans.
