FileNotFoundException thrown when the file does exists

Question

I\'m facing this strange problem.

I\'m trying to read a file that is located in another machine as a shared resource:

\\\\remote-machine\\dir\\MyFile         


        

Answer 1

I had a similar problem once. I think it has to do with the way java resolves remote files URI's. Try the following and see if it works:

File:////remote-machine/dir/MyFileHere.txt

I used the folowing example to verify the existence of a file in shared folders in my box and worked:

public static void main(String[] args) throws URISyntaxException{
    URI uri = new URI(args[0]); //args[0] = File:////remote-machine/dir/MyFileHere.txt
    File f = new File(uri);
    System.out.print(String.format("File %1$s Exists? %2$s", args[0],f.exists()));
}

Answer 2

Is the shared resource protected by a username and password? And if so, is your application engine running as that user? If your application engine is running as a Windows Service, the Windows service cannot be running as the "Local System Account". This account cannot access the network. You must configure your service to run as a user that has the rights to access the shared drive.

Answer 3

Have you checked the event logs on the server to see if it is being rejected? it could be that the program is running under a different user account than you think.

I'm not familiar with Java, but i know with some programs i've written i've had to allow Network Service to access the resources.

Actually i see that you have now ticked an answer as the correct one. oh and it was the same as my answer :) Cool!

Double check that the file is REALLY Called "MyFileHere.txt" and not "MyFileHere.txt.txt" If you are hiding the extention of the file this is an easy mistake to miss
