紧急求助！MyEclipse开发的JSP网站文件夹经常丢失

如题...
开完完成的网站，其中有一个目录是存储上传文件的文件夹。
用common-uploadFiles上传的文件。

但是现在发现，过几天我上传的文件夹就消失了...汗～这些文件在数据库中的数据依然存在
就是说除了这个文件夹其他的一切安好...

求教大虾们怎样解决？这可能是什么原因造成的呢？

附 -文件上传的那个Servlet：

package upload;

response.setCharacterEncoding("gb2312");
String uploadPath=this.getServletContext().getRealPath("")+"\\upload"; //上传文件的目录
Music file;
try {
file = upload(request, response, uploadPath);
musicDAO.addMusic(file);
PrintWriter out=response.getWriter();
out.println("<script language='javascript'>alert('感谢您的分享！');</script>");
out.println("<script language='javascript'>window.close();</script>");
} catch (Exception e) {
System.out.println("请确认文件格式或大小是否合法！");
response.sendRedirect("index.jsp");
}
}
//上传文件方法
public Music upload(HttpServletRequest request, HttpServletResponse response,String uploadPath)
throws Exception {
Music file=null;
String tempPath=uploadPath+"\\buffer"; // 临时文件目录
//初始化文件夹

if (!uploadFile.exists()) {
uploadFile.mkdirs();
}

}

// 创建表单工厂
DiskFileItemFactory factory = new DiskFileItemFactory();

// Set factory constraints
factory.setSizeThreshold(4096); // 设置缓冲区大小，这里是4kb

// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);

// Set overall request size constraint
upload.setSizeMax(10*1024*1024); // 设置最大文件尺寸，这里是10MB

List<FileItem> items = upload.parseRequest(request);// 得到form所有数据

while (i.hasNext()) {

//取得file外其他类型的参数

if(fi.getFieldName().equals("music_info")){
String music_info=fi.getString("gb2312").replace("\n", "<br/>");
file.setMusic_info(music_info);
}
}
String fileName = fi.getName();
if (fileName != null && CheckType.checkType(fileName)) {
file=new Music();
Date date=new Date();
//获取时间字符串用来做urlName
String urlName =date.toLocaleString().replace(":", "");
//创建存储到空间的文件
File savedFile = new File(uploadPath, urlName+".mp3");
//存储File的属性
String ip=request.getRemoteAddr();
file.setMusic_postip(ip);
file.setMusic_url(savedFile.getName());
//System.out.println("上传路径文件名："+fullFile.getName());
fi.write(savedFile);
}
}
return file;
}
}
