网上想找现成的，可是找不到，没得法只好（修改源程序）自己动手做了一个。
在自己机子上测试成功，可以支持中文。

没想到下载的人会这么多。
我把测试代码发出来，简单三个文件。
jsp页面：
<%@ page contentType="text/html;charset=GBK"%>
<html>
<head>
<title>File Upload</title>
</head>
<body>
<font size=5 color=#FF0000> <b>文件上传----使用jspsmart upload组件</b> </font>
<br>
<form action="uploadfile" method="post" enctype="multipart/form-data">
