FileNotFoundException (Permission Denied)
提问by Mike Nitchie
All, I'm using commons-FileUpload to allow my students to upload their assignments to my server through the class website. It works just fine running tomcat/eclipse on my local machine. However, when testing it on my server I have through digitalocean.com I am getting a FileNotFoundException (PermissionDenied).
所有，我正在使用 commons-FileUpload 允许我的学生通过课堂网站将他们的作业上传到我的服务器。在我的本地机器上运行 tomcat/eclipse 运行良好。但是，当我通过 digitalocean.com 在我的服务器上测试它时，我收到了 FileNotFoundException (PermissionDenied)。

The offending code:
违规代码：
try {
for (FileItem fi : uploaded) {
fi.write(new File(saveDirectory + fileName + "_"
+ FilenameUtils.getName(fi.getName())));
}
} catch (Exception e) {
e.printStackTrace();
response.sendRedirect("/uploadFailed.jsp");
return;
}
I just chmodded the directories that the program writes to so they are all drw-rw-rw-. Any tips?
我只是修改了程序写入的目录，所以它们都是drw-rw-rw-. 有小费吗？

The answer was to chmod 777 instead of 666.
答案是 chmod 777 而不是 666。
