Re: Summary of Network logging for Java desktop application

Bear in mind that java.util.logging has a working JMX MBean for dynamically
turning up/down the logging levels (point JConsole at your desktop app and
look at the MBeans tab to see what I mean), which can be enormously powerful
in a running app server (less so for a client-side app), and log4j's JMX
support appears to be essentially of alpha quality or nonexistent (Google
isn't clear on this point). I'm not sure why log4j has such spotty JMX
support, given it's (IMHO) better support in other areas of logging, but
c'est la vie.
