如果用的是STRUTS，下载 STRUTS 1.1 包
在STRUTS-EXAMPLES 的目录里面，有一个 struts-upload 的目录。
那里有源代码。自己看下就知道了！
用了enctype="multipart/form-data" 后，本页面的控件的值，在下个页面怎么取得啊
原来是request.getParameter("控件名")，不知道现在是什么啊？？？？？
struts - Uploader Exmple
bbs.ntsky.com
里面有下载模块,配制采用xml,自己写的上传类，bean也是公开的。
我现在已经用了jspsmartupload组件，但又遇到两个问题：
form用了enctype="multipart/form-data" 后，本页面的控件的值，在下个页面怎么取得啊，原来是request.getParameter("控件名")，不知道现在是什么啊？？？？？
还有用了jspsmartupload组件后，我的download是先上传再下载的，在下载时点取消的话，怎么对已经上传了的文件进行删除呢？
希望各位能回答
虽然用了jspsmartupload组件，还是有问题没解决。（我的download是先上传再下载的，在下载时点取消的话，有时文件被删除了，有时文件还在，好像是分奇偶的，很是莫名），不过就上传的问题是解决了，所以结贴了。
谢谢大家的踊跃回答！
