COS文件上传组件在Struts1.X环境下的问题[SOS]
[SOS]紧急救援
问题是这样的：
我使用文件上传组件COS进行文件的上传操作，按照COS的例子，我也成功的做了一个Demo,但这个Demo是这样的.有两个JSP文件:
a.jsp(用于生成上传界面)
upload.jsp(内嵌了javaCode实现文件上传操作)
我想对他进行点改进，就是说：我实现文件上传的代码我想写在StrutsAction中，而不是嵌在一个JSP里面.具体我是怎么写的，请看下面的代码:
a.jsp的代码如下:
upload.jsp的代码如下:
通过上面的两个JSP文件，我成功的完成了我的上传操作!
但是，我把它移植到Struts的Action中就报错了。请继续往下看:
a-1.jsp的代码如下:
UploadActionForm.java的代码如下:
UploadAction的代码如下:
我请求这个页面的时候，控制台报出如下错误信息:
不知如何解决，请指教,
鞠躬!

a.jsp的代码如下:
<!-- 测试集成COS文件上传效果 --> <%@ page contentType="text/html; charset=GBK"%> <html> <body> <form name="form1" method="post" enctype="multipart/form-data" action="upload.jsp"> <input name="file1" type="file"><br> <input name="file2" type="file"><br> <input name="file3" type="file"><br> <input type="submit" name="Submit" value="上传"> </form> </body> </html>
upload.jsp的代码如下:

<%@ page import="com.oreilly.servlet.MultipartRequest" %>
<%@ page import="java.io.File" %>

<body>
<%
String saveDirectory = "c:\\upload";
//每个文件最大5m,最多3个文件
int maxPostSize = 3 * 5 * 1024 * 1024;
//response的编码为"gb2312",同时采用缺省的文件名冲突解决策略,实现上传
MultipartRequest multi = new MultipartRequest(request,saveDirectory,
maxPostSize, "gb2312");
//输出反馈信息
Enumeration file = multi.getFileNames();
while (file.hasMoreElements()) {
String name = (String) file.nextElement();

String fileName = multi.getFilesystemName(name);
String lastFileName = saveDirectory + "\\" + fileName;
out.println("文件已经上传到:" + lastFileName);

UploadActionForm.java的代码如下:
public class UploadActionForm extends ActionForm {
private FormFile file1 = null;
private FormFile file2 = null;
private FormFile file3 = null;

UploadAction的代码如下:
public class UploadAction extends Action {
