public class SearchController extends HttpServlet{
    private static final long serialVersionUID = 1L;
    public void doPost(HttpServletRequest request, HttpServletResponse response)
                      throws IOException, ServletException{
        String searchWord = request.getParameter("searchWord");
        SearchManager searchManager = new SearchManager(searchWord);
        List searchResult = null;
        searchResult = searchManager.search();
        RequestDispatcher dispatcher = request.getRequestDispatcher("search.jsp");
        request.setAttribute("searchResult",searchResult);
        dispatcher.forward(request, response);
    }       public void doGet(HttpServletRequest request, HttpServletResponse response)
                   throws IOException, ServletException{
       doPost(request, response);
    }
}
jap 文件如下 ：
<%@page import="java.util.*"%>
<%@page import = "sample.dw.paper.lucene.search.SearchResultBean"%>
<FORM name = "lunce" method="post" id="searchForm" action="searchController">  
   <tbody>
      <tr>
         <td colspan = "3" >
          <input name = "searchWord" id = "searchWord" type = "test" size="60">
          <input id = "dosearch" type = "submit" value="search">
         </td>
      </tr>
   </tbody>
</FORM>
web.xm l如下
<?xml version="1.0" encoding="UTF-8"?>
<web-app>
<servlet>
        <servlet-name>SearchController</servlet-name>
        <servlet-class>SearchController</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>SearchController</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
</web-app>
Eclipse ＋ tomcat 
报404错误，description The requested resource (/sample.dw.paper.lucene/searchController) is not available.
用jsp调用servlet应该是没有错地。。

Answer 1

你的 url-pattern 设为了“/hello”，在 form 的 action 中也应为“/hello”啊，你给“searchController”去做了，所以就不对了～～<servlet-class>SearchController</servlet-class>，你的 SearchController 类没有包名吗？
