刚刚开始学习使用jsp，在上传图片的时候遇到了问题
我的主页代码
[code="java"]<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
|

[/code]
上传文件（do_upload.jsp）代码
[code="java"]
<%@page contentType="text/html;charset=gb2312" language="java"%>
<%@page import="java.util.*" %>
<%@page import="com.jspsmart.upload.*"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<title>do_upload</title>
<meta http-equiv="pragma" content="no-cache">

上传中....
<%
//上传附件
SmartUpload myUp=new SmartUpload();
myUp.initialize(this.getServletConfig(),request,response);
myUp.setAllowedFilesList("jpg,jpeg,bmp");
//myUp.service(request,response);
out.println("test1");
myUp.save("/upload");//文件保存到目录upload中
try{
myUp.upload();
}catch(Exception e)
{
e.printStackTrace();
}
File f=myUp.getFiles().getFile(0);
String fn=myUp.getFiles().getFile(0).getFieldName();
f.saveAs("/upload/"+fn,myUp.SAVE_VIRTUAL);
out.println(fn);
out.println("文件已经完成上传，请查看,看文件是否上传成功");
%>
[/code]
已经根据网上的文章改了很多次了，可是在上传的时候还是会有错误，请大家帮我看看，是哪里出问题了
错误代码如下：
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception

29: //myUp.service(request,response);
30: out.println("test1");
