java.util.logging: how to set level by logger package (or prefix)?

Question

My app uses many libraries and I'm using java.util.logging for logging. I'd like to be able to set different logging levels for each library by doing something like:

org.datanucleus.*.level = WARNING
com.google.apphosting.*.level = WARNING
com.myapp.*.level = FINE

Is is possible?

Answer 1

You shouldn't use "*". A sample logging.properties could be such as:

handlers=java.util.logging.ConsoleHandler
.level=ALL

java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter

org.datanucleus.level=WARNING
org.datanucleus.handler=java.util.logging.ConsoleHandler

com.myapp.level=FINE
com.myapp.handler=java.util.logging.ConsoleHandler

And if all "org" level should be logged as WARNING then

org.level=WARNING
org.handler=java.util.logging.ConsoleHandler
