jave web 批量上传
我的需求是这样的：Servlet+JSP 进行开发 只有一个<input type="file"/>，可以选择多个文件上传，服务器端接收这些文件，将它们的路径保存到数据库中。我在网上看了很多，要用到swfupload组件，可是我不会用这个组件（老外写的，看不懂）。请高手给指点一下，如果代码太多，可以发到我的邮箱里：jianghaodongok@yahoo.cn 如能解决问题，不胜感激。

<script type="text/javascript" language="javascript">
var uploaderMgr = new HttpUploaderMgr();
uploaderMgr.Load();//加载控件
window.onload = function()
{
uploaderMgr.Init();//初始化控件
//添加一个本地文件
uploaderMgr.AddFile("D:\\Soft\\QQ2010.exe");
uploaderMgr.PostFirst();
};
</script>
服务器返回消息：<input id="txtFilePath" type="text" size="50" />
<script type="text/javascript" language="javascript">
var uploaderMgr = new HttpUploaderSingleMgr();
uploaderMgr.Config["PostUrl"] = "http://localhost:8080/asp.net/upload.aspx";
uploaderMgr.Load();
//文件上传完成后执行的回调函数
uploaderMgr.CompleteHook = function(msg)
{
document.getElementById("txtFilePath").value = msg;
};
window.onload = function()
{
uploaderMgr.Init();
};
