将此文件保存为testimageout.jsp文件。下一步要做的工作就是使用HTML标记：
<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*" %>
<%@ page import="java.util.*"%>
<%@ page import="java.text.*"%>
<%@ page import="java.io.*"%>
<jsp:useBean id="conn" scope="page" class="dbconn.DBResult"/>
<%
String path = request.getContextPath();
String basePath = request.getScheme() "://" request.getServerName()
":" request.getServerPort() path "/";
%>

<base href="<%=basePath%>">
