The JVM in which a WebLogic Server instance runs, sends messages to standard error and standard out. Server as well as application code write directly to these streams instead of using the logging mechanism. You can redirect the JVM output to all the registered log destinations, like the server terminal console and log file.
For more information, see Redirecting JVM Output.
Result
