Log4j is not catching exceptions

I am using google app engine and I am having trouble with log4j. Basically I am testing my app and the exceptions are being detected by the dashboard, but not log4j. I am using the following:

 catch (Exception e) {
       logger.warn("Exception Alert", e);
       e.printStackTrace();
   }

Is this the correct way to catch exceptions using Log4j? It works for some exceptions now. But not all. I want to catch a NumberFormatException (empty string) but this is isn't working.

Yes, it's correct but the logger should be initialized via LogFactory.getLog() and log level should be at least WARN. Also log4j should be on classpath and configured like in this examples.
