log4j 问题，请兄弟们帮忙

log4j.appender.CONSOLE=org.org.apache.log4j.ConsoleAppender
                          ^
                          |
                      这两个org是什么意思？？

先謝謝大家的幫忙,改了還是顯示如果錯誤:
14:28:36,078 INFO [JkMain] Jk running ID=0 time=0/63 config=null
14:28:36,265 INFO [TilesRequestProcessor] Tiles definition factory found for re
quest processor ''.
ERROR: invalid console appender config detected, console stream is looping

invalid console appender config detected, console stream is looping--->死循环？

不用配什么target，console部分参照下面的配置就行了，console就是输出到控制台的。#### Use two appenders, one to log to console, another to log to a file
log4j.rootLogger=DEBUG, console, Rfile#### First appender writes to console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout# Pattern to output the caller's file name and line number.
log4j.appender.console.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

謝謝大家,我拷貝 wingtrace(暮寒.烟灰.风化物.天佑我的母亲) 的配置,還是顯示:
ERROR: invalid console appender config detected, console stream is looping 的錯誤

ERROR: invalid console appender config detected, console stream is looping

public class LogMgr {
private static LogMgr instance;
private LogMgr()
{
        PropertyConfigurator.configure(LogMgr.class.getResource("log4j.properties"));
}
public synchronized static LogMgr getInstance()
{
if (instance == null)
        {
            instance = new LogMgr();
        }
        return instance;
}
public Logger getLog(String arg0)
{
Logger logger = Logger.getLogger(arg0);
return logger;
}
}private Logger log=LogMgr.getInstance().getLog(AddClassAction.class.getName());
我的代碼侑問題嗎

晕，写这么冗余的代码，根本不用自己去写个什么LogMgr,纯粹多此一举。PropertyConfigurator.configure(LogMgr.class.getResource("log4j.properties"));随便丢在哪个你想初始化的地方。logger的获取和使用：给你看个例子：package log4jdemo;import org.apache.log4j.*;
class Test
{
//重点就下面这行,log4j自己提供了获取logger的静态方法，根本不用你自己去封装. private static final Logger logger = Logger.getLogger(Test.class);
public static void main(String[] args)
{
logger.info("Hello World!");
}
}

我想在系统启动时初试化
PropertyConfigurator.configure(LogMgr.class.getResource("log4j.properties"));
不用单体结构，不知道怎样配置，我用的是struts,我本来想做一个serverlet,配置到struts中，不知道怎样做．

java代码:package com.pigo.util;import java.io.*;

import javax.servlet.http.*;import org.apache.log4j.*;public class Log4jInitServlet extends HttpServlet {
    private static final String CONTENT_TYPE = "text/html; charset=GBK";    //Initialize global variables
    public void init() throws ServletException {
        //以下是log4j的初始化，可以把log4j.properties放到WEB-INF/class下让他自动初始化
        ServletContext sct = getServletContext();
        String prefix = sct.getRealPath("/");
        System.out.println("[....Log4j]: 初始化Log4j...");
        //下面的参数是从web.xml中寻找到的
        String file = getInitParameter("log4j_config");
        if (file != null) {
// 根据配置初始化log4j
            try {
                PropertyConfigurator.configure(loadproperties(prefix + file));
            } catch (Exception ex) {
                ex.printStackTrace();
            }
            PropertyConfigurator.configure(prefix + file);
            System.out.println("[....Log4j]: Log4j已加载...");
        } else {
            System.out.println("[....Log4j]: Log4j装载失败...");
        }    //Process the HTTP Get request
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws
            ServletException, IOException {
            response.setContentType(CONTENT_TYPE);
            PrintWriter out = response.getWriter();
            out.println("<html>");
            out.println("<head><title>Log4jInitServlet</title></head>");
            out.println("<body bgcolor=\"#ffffff\">");
            out.println("<p>The servlet has received a " + request.getMethod() +
                        ". This is the reply.</p>");
            out.println("</body>");
            out.println("</html>");
            out.close();
    }
            //Process the HTTP Post request
            public void doPost(HttpServletRequest request,
                               HttpServletResponse response) throws
            ServletException, IOException {
            doGet(request, response);
    }
            //Clean up resources
            public void destroy() {
    }
}
web.xml<servlet>
    <servlet-name>log4jinitservlet</servlet-name>
    <servlet-class>com.pigo.util.Log4jInitServlet</servlet-class>
    <init-param>
      <param-name>log4j_config</param-name>
      <param-value>/WEB-INF/log4j.properties</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>建议你先认真看一下log4j自带的文档。
