Java 使用XML的servlet

您好，我是Servlets新手，我正在尝试使用XML而不是注释编写应用程序。 下面是我的XmlServlet.java

package com.servlet.tutorial;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class XmlServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.getWriter().println("<p>Rahul is Rich</p>");
        // TODO Auto-generated method stub
    }

}

package com.servlet.tutorial；
导入java.io.IOException；
导入javax.servlet.ServletException；
导入javax.servlet.http.HttpServlet；
导入javax.servlet.http.HttpServletRequest；
导入javax.servlet.http.HttpServletResponse；
公共类XmlServlet扩展了HttpServlet{
受保护的void doGet（HttpServletRequest请求，HttpServletResponse响应）抛出ServletException，IOException{
response.getWriter（）.println（“Rahul是富的”
”；
//TODO自动生成的方法存根
}
}

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>SimpleServletProject</display-name>
   <servlet>
      <servlet-name>xmlServlet</servlet-name>
      <servlet-class>com.servlet.tutorial.XmlServlet</servlet-class>
  </servlet>
  <servlet-mapping>
      <servlet-name>xmlServlet</servlet-name>
      <url-pattern>xmlServletPath</url-pattern>
  </servlet-mapping>

</web-app>

我有个问题。当我尝试启动服务器时，出现了此错误
