struts 里面 FormFile上传文件的问题
FormBean里面用了FormFile类型对应上传文件
用流的方式保存到文件,
但是我提交后一直出下面这个错误
action里面都没执行就抛异常了.
网页的enctype(这个单词可能写错了,我忘记了)="multipart/form-date"我也设置的
请问是什么原因.

你的属性在actionform里没有注册，不能进行反射啊
给你段代码，这样做可以
Hashtable hash=form.getMultipartRequestHandler().getFileElements();
Iterator i = hash.values().iterator();
FormFile formFile = null;
// 依次处理每一个文件：
while(i.hasNext()) {
formFile = (FormFile)i.next();
out = new java.io.FileOutputStream(new File(uploadpath + File.separator+filename));
out.write(formFile.getFileData());
}
}
form为actionformTop

应该是你actionform里属性和页面不对应，应该要搁个Formfile formfile=new FormFile();
formfile为你页面上那个对象的名字Top
