How to set application logging properties

In development (for a NPA) to get the java logging to appear in the Application Log I set jvm args with


> -J-Dnetbeans.logger.console=true -J-ea 


This also displays in the IDE console and writes log messages to a file at build\testuserdir\var\log\messages.log. (What is -J-ea?)

But the format and filtering is not as I want. How can the properties of these log messages be configured?

I have tried my own properties file with


> -J-Djava.util.logging.config.file=logging.properties


but this stops the application console messages, and writes just to my new file location, and the IDE console.

Also how do I get the settings migrated within the install build so that log messages are enabled for the deployed application?
