JSP生成HTML

1、JSP
<%@ page contentType="text/html; charset=gb2312"%>
<%@ page import="java.util.*"%>
<%@ page import="java.sql.*"%>
<%@ page import="java.io.*"%>
<%@ page import="org.apache.commons.fileupload.*" %>
<%@ page import="java.text.*" %>
<%@ page import="javax.servlet.*,javax.servlet.http.*"%>
<jsp:useBean id="conn" scope="page" class="DBLink.DBSQL"/>
<jsp:useBean id="ReadTemplates" scope="page" class="ball.news.ReadTemplates"/>
<jsp:useBean id="WriteHtml" scope="page" class="ball.news.WriteHtml"/>
<jsp:useBean id="ReplaceAll" scope="page" class="ball.news.ReplaceAll"/>

%>
<%out.println("新闻生成html成功了！");%>

2、WriteHtml
WriteHtml.java

package ball.news;
