帮个忙,TOMCAT4.1.29,加载LINSTER说类找不到.....

[cultra]

主要目的实在系统启动的时候加载一XML格式菜单

原始代码如下:
package com.elkstudio.sms.web;

import javax.servlet.ServletContextListener;
import javax.servlet.ServletContextEvent;
import java.util.HashMap;

//FJSMS IMPORT
import com.elkstudio.sms.dao.MenuXmlDao;
import com.elkstudio.sms.web.SmsWebKeys;
import javax.servlet.ServletContext;
import javax.servlet.ServletContextAttributeEvent;

/**

* <p>Copyright: Copyright (c) elk studio 2003</p>
* <p>Company: elk studio </p>
* @author please enter your name
* @version 1.0
*/

public class MenuManager implements ServletContextListener{

private ServletContext context = null;

/**
* Log a message to the servlet context application log.
*
* @param message Message to be logged
*/
private void log(String message) {

if (context != null)
context.log("ContextListener: " + message);
else
System.out.println("ContextListener: " + message);

}


public void contextInitialized(ServletContextEvent event) {
this.context = event.getServletContext();
if (context.getAttribute(SmsWebKeys.SYSMENU_LOCATOR) == null) {
System.err.println("ready to get mi..............");
HashMap mi = (HashMap) MenuXmlDao.getMenuItems(MenuXmlDao.loadDocument(
"/WEB-INF/sysmenu.xml"));
context.setAttribute(SmsWebKeys.
SYSMENU_LOCATOR, mi);
System.err.println("get mi ok!");
}
log("contextInitialized()");
}



public void contextDestroyed(ServletContextEvent event) {
this.context = event.getServletContext();
if (context.getAttribute(SmsWebKeys.SYSMENU_LOCATOR)!=null)
context.removeAttribute(SmsWebKeys.SYSMENU_LOCATOR);
}
}


错误如下:
