Answer 1

s是enctype吗?这个应该没问题
<html:form action="fileAction.do?method=upLoadFile" enctype="multipart/form-data" onsubmit="return Mycheck()">

Answer 2

看看你的异常
java.lang.IllegalArgumentException: Cannot invoke com.actionForm.FileActionForm.setFile - argument type mismatch 
argument type mismatch  参数类型不匹配
你去看看你的上传 所对应的类型是什么类型
上传文件用 对应的类型应该为FormFile 
类型自己去看看吧

Answer 3

setFile - argument type mismatch   form中应该是 FromFile吧 
   

Answer 4

我就是 用的 FormFile 也报这个错误很是郁闷
