请教一个jspsmartupload组件的问题

[wdslhr]

我用的是jspsmartUpload 组件，我将jspsmartupload 组件的class文件转成我的.java文件，并加入到了我的工程里。
我在处理当中前一小段是这样写的：
<%@page contentType="text/html;charset=gb2312" >
<%@ page import="com.jspsmart.upload.*"%>


<%
int count=0;

//定义目标目录
String destination="d:/";
System.out.println("111111111111");
SmartUpload mySmartUpload =new SmartUpload()
mySmartUpload.initialize(pageContext);

//文件上传
mySmartUpload.upload();
//获得文本的内容
//上传的情况统计
System.out.println("111111111111");
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(i); ///在这里报错了


报的错是：<2005-8-21 下午12时08分05秒 CST> <Error> <HTTP> <BEA-101020> <[ServletContext(id
=1923341,name=ctadmin,context-path=/ctadmin)] Servlet failed with Exception

请问我这里什么地方出了错呀？

偶以前用smartupload,有时候运行正常,有时候就出类似的错误,呵呵.觉得这个东西写的有问题,以后就没再用过.

不好意思，上面报错处写错是应该是
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(0); ///在这里报错了
