Answer 1

包版本不对 参考 http://topic.csdn.net/u/20071022/15/1de77ef5-fc08-4bff-83f6-ea172c176277.html

Answer 2

commons-fileupload-1.0.jar  
commons-fileupload-1.1.jar  
commons-fileupload-1.2.jar
都试过了，还是一样的问题  

Answer 3

不管你用什么包，直接把包放进build path,看看有没有org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest
这个方法啊，我估计没有，那当然报错

Answer 4

  上传附件时那个form定义错误!
