How to disable log4j for applet?

[nikolaykuz]

There is line in the code

PropertyConfigurator.configure(properties);

If run my app as applet it generates this error/warning in Java Plugin Console. This is normal behavior because applet is not supposed to perform external io operations. But how I can disable log with out any warnings?

If I comment the code line still

AppletApp.init()
log4j:WARN No appenders could be found for logger (org.evogame.client.swing.AppletApp).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
basic: Applet initialized

Is this server or client? Client is not having a dependency on log4j. At server side, one option I can think of is, change the properties file to have ConsoleAppender instead of file appender and then turn the logging off.
log4j.appender.toLogFile=org.apache.log4j.ConsoleAppender. I have not tried this in applet so not sure if it will work.

It was a client. I just forget to eliminate this kind of lines:

private static final Logger LOG = LoggerFactory.getLogger(MyClass.class);
