Configuring Logging in Glassfish

Calls to System.out.println are logged at the INFO level using the logger name javax.enterprise.system.stream.out. Calls to System.err.println are logged at the WARNING level using the logger name javax.enterprise.system.stream.err. To turn off the logs from these sources, specify the logger name with the value OFF in the Additional Properties area.
