title: Logging to Oracle Application server log files
body: <p>I have an application that works fine on tomcat, but when I deployed it on Oracle Application Server, I get some errors.</p>
  
  <p>I need to log some values in my code but cannot do that... </p>
  
  <p>When I write <code>System.out.println("bla bla")</code> in my code, I couldn't see that msg on the log files</p>
  
  <p>Why that?</p>
  
  <p>NOTE, I am taking about application log files <a href="http://download.oracle.com/docs/cd/B32110_01/core.1013/b32196/log.htm#i1016126" rel="nofollow">http://download.oracle.com/docs/cd/B32110_01/core.1013/b32196/log.htm#i1016126</a></p>
