Log 4 j error in struts 1.2.8

Question

I am using struts1.2.8 with hibernate 3.
I am getting below error.
Is there any solution for this problem ?
private DailyRollingFileAppender cAeroAppender;
     java.util.Calendar cal=java.util.Calendar.getInstance(); // getting calendar instance
                    logger = Logger.getLogger(cal.getTime()+"");
strLogLevel=CAeroConstants.getProperty(CAeroConstants.PROPTYPE_CONFIG,CAeroConstants.CONFIGPROP_LOG_LEVEL);
                         logger.setLevel(Level.DEBUG);
                    else if ( strLogLevel.equalsIgnoreCase("DEBUG") ) {
                         logger.setLevel(Level.DEBUG);
                    else if ( strLogLevel.equalsIgnoreCase("ERROR") ) {
                         logger.setLevel(Level.ERROR);
                    cAeroAppender = new DailyRollingFileAppender(new SimpleLayout(),strLogPath+".log","'_'MM-dd-yyyy");
                    logger.addAppender(cAeroAppender);

It's not an error; it is merely a warning saying that the system is unable to find any log4j configuration. Create a log4j.properties and add it to the server classpath.
