第三个是我的一个上传页面 uploadphoto.jsp页面
<%@page contentType="text/html; charset=GBK" import="java.util.HashMap"%>
<a onClick="javascript:window.open('jsp/uploadphoto.jsp','myfacewindow', 'height=100,width=440, top=350, left=400, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, status=no');" style="cursor:hand;">
<span class="STYLE2">上传</span></a> 推荐最佳比例为:(50px*50px)
<style>
<!--
body{
margin-left:0px;
margin-top:0px;
margin-right:0px;
margin-bottom:0px;
}
.STYLE1 {

}
.STYLE2 {

font-weight: bold;
}
-->
</style>
<html>
<title>上传图片</title>
<body>
</br>
<span class="STYLE2">商务客图片上传</span><br/>
<span class="STYLE1">请您选择您要上传的图片，图片推荐：50像素*50像素！使用.jpg .gif .bmp格式</span>

请问各位大侠，我这两个类可不可以连接到上传文件哦 我是的是Struts1.2, 是不是需要一个数据传输对像DTO层，从数据库中把它的值提取出来了，谢谢给位大侠帮我这个忙！
