java.io.FileNotFoundException: (The system cannot find the path specified)

Question

I am new to Socket programming. I am trying to write a file on server, but my code throws an exception:

java.io.FileNotFoundException: Welcome-PC\IndiraSharing\hadoop.txt (The system cannot find the path specified)

Here is my code.

   Socket s;

   ServerSocket server = new ServerSocket(5555);

   String serveradd;
   serveradd=s.getInetAddress().getHostName();
  //  System.out.println("Server accepted client");
    InputStream input = s.getInputStream();
    BufferedReader inReader = new BufferedReader(new InputStreamReader(s.getInputStream()));
    BufferedWriter outReader = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
    String filename = inReader.readLine();
    if ( !filename.equals("") ){      

        outReader.write("READY\n");
        outReader.flush();
    } 

     FileOutputStream wr = new FileOutputStream(new File(serveradd+"\\IndiraSharing/" +     filename));
    byte[] buffer = new byte[s.getReceiveBufferSize()];
    int bytesReceived = 0;
    while((bytesReceived = input.read(buffer))>0)
    {
             wr.write(buffer,0,bytesReceived);
    }

Solution

The directory cannot be found. The message is confusing because it talks of "file" but in Java IO, a directory is a File too.

If you run:

File dir = new File(serveradd+"\\IndiraSharing")
System.out.println(dir.exists());

It will print:

false

You could try to create the directory structure:

dir.mkdirs();

Also, check the absolute path is what you are expecting:

System.out.println(dir.getAbsolutePath());
