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?

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
