i m having loggers.java as

package com.pronto.util;

import java.io.*;
import java.util.*;
import org.apache.log4j.*;

/**

public class Loggers {

  public static int DEBUG_LOG_LEVEL = 10000;
  public static int INFO_LOG_LEVEL = 20000;
  public static int ERROR_LOG_LEVEL = 40000;

  private static PrintWriter _printWriter = null;
  private static String _logFile = null;
  private static int _logLevel;
  private static Logger logger =
Logger.getLogger("com.pronto.web");

  public static TreeMap levels = new TreeMap();
  static {
    levels.put(String.valueOf(DEBUG_LOG_LEVEL),
"DEBUG");
    levels.put(String.valueOf(INFO_LOG_LEVEL),

    levels.put(String.valueOf(ERROR_LOG_LEVEL),
"ERROR");
    _logLevel = logger.getLevel().toInt();
	ConsoleAppender app
=(ConsoleAppender)logger.getAppender("Log");
   // RollingFileAppender app

   // _logFile = app.getFile();
  }

  public synchronized static void logMessage(Object

	  System.out.println("got into log message");
    /*if(logLevel == ERROR_LOG_LEVEL)
	  {
      logger.error(message);
	  }

    else
	  {*/
		System.out.println("got into debug message");
      logger.debug(message);
	  //}
  }

    if( logger.getLevel().toInt() != level ) {
      if(level == DEBUG_LOG_LEVEL)
        logger.setLevel(Level.DEBUG);

        logger.setLevel(Level.INFO);

      logMessage("Cleared out logfile",
logger.getLevel().toInt());
    }
    catch(Exception e) {
      logMessage("Error while Clearing logfile
"+e.getMessage(), ERROR_LOG_LEVEL);
    }
  }

  public static void writeFileToWriter(Writer out) {
    try {
      BufferedReader br = new BufferedReader(new
FileReader(_logFile));
      char[] buff = new char[2048];
      int bytesRead;

      while(-1 != (bytesRead = br.read(buff, 0,
buff.length))) {
        out.write(buff, 0, bytesRead);
      }
      br.close();
    }
    catch(Exception e) {
      Loggers.logMessage("Error while writing the file
to writer " +e.getMessage(),ERROR_LOG_LEVEL);
    }
  }

  public static int getLoggingLevel() {
    return _logLevel;
  }

  private Loggers() {
  }
  public static void main(String[] args) 
	{
		System.out.println("Hello World!");
		Loggers.logMessage("stupid..idiot",
Loggers.ERROR_LOG_LEVEL);
	}
}
	

i m calling that in actionform class as 

Loggers.logMessage("stupid..idiot",
Loggers.DEBUG_LOG_LEVEL);

tell me solution
