java.io.FileNotFoundException没有此类文件或目录错误，但目录存在

Question

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?

Answer 1

it turns out this was due to my firewall (firestarter) blocking my servers ip address. I allowed the exception and everything worked.

Answer 2

A few of thoughts (hopefully you haven't tried them :-):

Do you have read access to the directory?

Try putting in something like:

System.out.println("the directory = " + directory);

Assuming "directory" is the File variables that holds the directory.

Try putting in something like:

System.out.println("the directory exists = " + directory.exists());

and making sure it returns true.

Answer 3

您是否对所有中间路径段具有遍历权限，并且对最终文件具有适当的权限？
