If you’ve ever used the built-in logging facilities introduced in JDK 1.4, you’ve certainly faced a situation wherein you wanted to prevent log messages from appearing on the console. The quickest way to accomplish this is to change the logger settings in J2SE installation directory:

1. Locate file jreliblogging.properties.
2. Find the following configuration parameter:

   java.util.logging.ConsoleHandler.level = INFO                          

3. Replace it with the following string:

   java.util.logging.ConsoleHandler.level = OFF
