java.io.FileNotFoundException No such file or directory error but directory exists
提问by Atma
I'm getting the filenotfoundexception on my apps directory but my directory clearly exists. I'm doing this on my local machine. I'm doing a very simple post to a servlet. Does anyone knw what could be happening?
我在我的应用程序目录中收到 filenotfoundexception，但我的目录显然存在。我在我的本地机器上这样做。我正在对 servlet 做一个非常简单的帖子。有谁知道会发生什么？
回答by Atma
it turns out this was due to my firewall (firestarter) blocking my servers ip address. I allowed the exception and everything worked.
原来这是由于我的防火墙（firestarter）阻止了我的服务器 IP 地址。我允许例外，一切正常。

A few of thoughts (hopefully you haven't tried them :-):
一些想法（希望你还没有尝试过:-)：
Do you have read access to the directory?
你有目录的读权限吗？
Try putting in something like:
尝试输入以下内容：
System.out.println("the directory = " + directory);
Assuming "directory" is the File variables that holds the directory.
假设“目录”是保存目录的文件变量。
Try putting in something like:
尝试输入以下内容：
System.out.println("the directory exists = " + directory.exists());
and making sure it returns true.
并确保它返回true。

Do you have traversal authority to all intervening path segments, and appropriate authority to the final file?
您是否拥有对所有中间路径段的遍历权限，以及对最终文件的适当权限？
