下面的代码是调用的：aftsearch.jsp
<%@ page contentType="text/html; charset=gb2312" %>
<%@ page import="java.util.*" %>
<%
request.setCharacterEncoding("GB2312");
String keyword=request.getParameter("keyword"); //接收关键字
String trace=getServletContext().getRealPath("/")+"xwxx\\news\\";//主体新闻存放路径
NEWS.newsSearch newsSearch=new NEWS.newsSearch();//初始化检索的bean
newsSearch.setFilePath(trace);//设置主体新闻路径
newsSearch.setKeyWord(keyword);//设置关键字
newsSearch.search();//检索
Vector news=newsSearch.getResult();//取到结果
%>
