serlet访问不了jsp,高手指点
这是完正的程序代码帮忙看看
package my_home;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;

public class news_add_get extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
String nesws_art=request.getParameter( "art ");
System.out.println(nesws_art);

}
//Clean up resources
public void destroy() {
}
}

服务器报错：StandardHost[localhost]: MAPPING configuration error for request URI
StandardHost[localhost]: Removing web application at context path /web_home

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN " "http://java.sun.com/dtd/web-app_2_3.dtd ">

<servlet>
<servlet-name> news_add_get </servlet-name>
<servlet-class> my_home.my_home.news_add_get </servlet-class>
</servlet>

<servlet-mapping>
<servlet-name> news_add_get </servlet-name>
<url-pattern> /news_add_get </url-pattern>
</servlet-mapping>
</web-app>
