How to initialise servlet?

Hi! I am very new to servlet and would appreciate your assistance in this problem.
I am using j2sdk1.3.1_08, Tomcat 4.1.27, Log4j 1.2.28

I would like to initialise log4j using servlet. Following are the codes I used. Somehow, this servlet does not get initialised as there are no logs generated. But if I run runLog.jsp following by test.jsp, it works. Do you know why?

------ runLog.jsp ---
<%@ page import="org.apache.log4j.*"%>

<%
Logger logger = Logger.getLogger(getClass());

String LogConfigFilePath = getServletContext().getRealPath("/")+"WEB-INF/classes/config/log4j.properties";
BasicConfigurator.resetConfiguration();
PropertyConfigurator.configure(LogConfigFilePath);

logger.info("runLog successful");
%>

------ WEB-INF/class/com/log/Log4jInit.java ----
package com.log;
import org.apache.log4j.*;
import javax.servlet.http.*;

public class Log4jInit extends HttpServlet {
public void init() {

String LogConfigFilePath = getServletContext().getRealPath("/") + "config//log4j.properties";

BasicConfigurator.resetConfiguration();
PropertyConfigurator.configure(LogConfigFilePath);

public void doGet(HttpServletRequest req, HttpServletResponse res) {}

}

--- web.xml ---
<servlet>
<servlet-name>log4j-init</servlet-name>
<servlet-class>com.log.Log4jInit</servlet-class>
<init-param>
<param-name>log4j</param-name>
<param-value>WEB-INF/classes/config/log4j.properties</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

--- test.jsp ---

<%@ page import="org.apache.log4j.*" %>

<% Logger logger = Logger.getLogger("test.jsp");
logger.info("befor say hi");
%>

<h3> Hi</h3>

<% logger.info("after say hi");%>

>------ WEB-INF/class/com/log/Log4jInit.java ----
 but do you have ?
WEB-INF/classes/com/log/Log4jInit.class

Also, show  us your servlet mapping element in your web.xml
Tuan_JeanAuthor Commented:
Yes. I do have WEB-INF/classes/com/log/Log4jInit.class


The servlet mappting is as follow:

--- web.xml ---
<servlet>
<servlet-name>log4j-init</servlet-name>
<servlet-class>com.log.Log4jInit</servlet-class>
<init-param>
<param-name>log4j</param-name>
<param-value>WEB-INF/classes/config/log4j.properties</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

HI Tuan_Jean.
Can you tell me what exactly you did to solve the proble, so that I could also know.
Thx for your help!
Tuan_JeanAuthor Commented:
This is what I used:

String LogConfigFilePath = getServletContext().getRealPath("/")
String file = getInitParameter("log4j");
