又有了点分，请教log4j的问题

[owowo]

我的 web.xml 里加入如下代码
<servlet>
<servlet-name>log4j-init</servlet-name>
<servlet-class>com.jstf.wlcb.util.Log4jInit</servlet-class>
<init-param>
<param-name>log4j</param-name>
<param-value>WEB-INF/log4j.properties</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>


log4j.properties 文件代码如下

log4j.rootLogger=INFO,A1,R

log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout

log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%c]-[%p] %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender

log4j.appender.R.File=C:/java/tomcat4.1/webapps/wlcb/sys.html

log4j.appender.R.MaxFileSize=5000KB

log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.HTMLLayout
log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c] [%p] - %m%n


Log4jInit.java 文件代码如下

package com.jstf.wlcb.util;

import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.log4j.*;

public class Log4jInit
extends HttpServlet {

public void init() throws ServletException {
String prefix = getServletContext().getRealPath("/");
String file = getInitParameter("log4j");

if (file != null) {
PropertyConfigurator.configure(prefix + file);
}

}

public void destroy() {
}
}

配置好后启动tomcat时报错，但是log4j使用正常，请教问题出在哪，如何解决？
