Answer 1

Struts 有自带的上传，下载的组建～
　　简单调用就行～

Answer 2

java.lang.IllegalArgumentException: Cannot invoke org.seacat.form.CopyfileForm.setFile1 - 是填充form的时候出错的吧。。看JSP或配置文件有没有问题。

Answer 3

看了啊 没什么问题, shuai45你说的主建 是哪个

Answer 4

是JSP的问题 但是还是出现个错误
java.lang.IllegalArgumentException: Path success.jsp does not start with a "/" character
