再次请教大侠，我的文件上传功能为什么不能使用？

我安装的是ｊｄｏｎ２．５

上传文件时候，报错：

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: MultipartRequest()Not a directory: /home/bqlr/jive/upload/
com.jdon.picture.MultipartFormServ.doPost(MultipartFormServ.java:60)
javax.servlet.http.HttpServlet.service(HttpServlet.java:763)
javax.servlet.http.HttpServlet.service(HttpServlet.java:856)

请大侠指点迷津

谢谢
