How do I setup a EAR and a Glassfish Server that it shows FINE level on the development server but the same ear shows INFO level on the productive machines?
In the moment I change config in the persistence.xml every time i deploy onto the productive machines. But s.t. i forget and the machine starts flooding the log files.
回答1:
You must put in the
<jvm-options>-Declipselink.logging.level=FINE</jvm-options>
into your config.xml java-config tag on your development machine.
And do NOT put in the logging level property into the persistence.xml.

You can also set the EclipseLink log level using System properties (or you could set the log level in code using a SessionCustomizer).
