问题
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).
Stack trace:
java.io.FileNotFoundException:
/uploads/cosc111fall2013/Assignment1/Program1.java (Permission denied)

The offending code:
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?
回答1:
The answer was to chmod 777 instead of 666.
