java.io.FileNotFoundException No such file or directory error but directory exists

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 hap开发者_C百科pening?

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

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.

Do you have traversal authority to all intervening path segments, and appropriate authority to the final file?
