title: Google App Engine - Can not find my logging messages
body: <p>I can not find the results of my logging calls.
  To log messages I tried both: </p>
  
  <pre><code>System.out.println("some message"); 
  </code></pre>
  
  <p>and </p>
  
  <pre><code>Logger logger = Logger.getLogger("MyLogger"); // Logger is java.util.logging.Logger 
  
  // ... 
  
  logger.info("some message"); 
  </code></pre>
  
  <p>I have deployed my app and after few tests I decided check out some 
  log messages. But there were no messages. I changed minimum severity 
  level to "Info" from default "Error", and only messages i've seen were 
  service messages like this: </p>

  <p>I would also be grateful if someone show a little snippet with logging some data (if it's works) - I suspect my problem may be the one of that stupid problems when somewhat incorrectly located comma can be the cause of situation.</p>
