applicationContext.xml在Web.xml中启动时不能初始化的一个大问题！请指教！

这是我的web.xml配置文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>
org.apache.struts.action.ActionServlet
</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>

</init-param>

</parame-value>
</context-parame>
<lister>
<lister-class>
org.springframework.web.context.ContextLoaderListener
</lister-class>
</lister>

   

<welcome-file-list>
<welcome-file>use.jsp</welcome-file>
</welcome-file-list>
</web-app>

下面是我的一个baseAction在程序运行后的调用：


package com.test.struts.action;

import org.apache.commons.beanutils.BeanUtils;
import org.apache.struts.actions.DispatchAction;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

public class BaseAction extends DispatchAction
{
ApplicationContext ur=null;
public BaseAction()
{
super();
}

    public void copyProperties(Object to, Object from) throws Exception {
        BeanUtils.copyProperties(to, from);
    }
    public Object getBean(String name)
    {
    if (ur == null) {
ur = WebApplicationContextUtils.getRequiredWebApplicationContext(servlet.getServletContext());
    }
    return ur.getBean(name);
    }
但是在调用这个方法时就会出现如下错误：


HTTP Status 500 -
