FileNotFound Exception in FileOutputStream

Question

I'm getting error of FileNotFound. Basically, I'm trying to upload file from client to server.

Please, help me with it.

This is client.java class package ftppackage;

import java.net.*; 
import java.io.*; 

public class Client { 

    public static void main (String [] args ) throws IOException { 
        Socket socket = new Socket("127.0.0.1",15123); 
        File transferFile = new File ("D:\\AsiaAd.wmv");
        byte [] bytearray = new byte [(int)transferFile.length()];
        FileInputStream fin = new FileInputStream(transferFile);
        BufferedInputStream bin = new BufferedInputStream(fin);
        bin.read(bytearray,0,bytearray.length);
        OutputStream os = socket.getOutputStream();
        System.out.println("Sending Files...");
        os.write(bytearray,0,bytearray.length);
        os.flush();
        socket.close();
        System.out.println("File transfer complete");
    }
} 

And this is my server.java class

package ftppackage;

import java.net.*;
import java.io.*;

public class Server {

    public static void main (String [] args ) throws IOException {
        int filesize=1022386;
        int bytesRead;
        int currentTot = 0;
        ServerSocket serverSocket = new ServerSocket(15123);
        Socket socket = serverSocket.accept();
        System.out.println("Accepted connection : " + socket);
        byte [] bytearray = new byte [filesize];
        InputStream is = socket.getInputStream();
        FileOutputStream fos = new FileOutputStream("E:\\0\\"); // it is creating new file not copying the one from client
        BufferedOutputStream bos = new BufferedOutputStream(fos);
        bytesRead = is.read(bytearray,0,bytearray.length);
        currentTot = bytesRead;
        do {
            bytesRead = is.read(bytearray, currentTot, (bytearray.length-currentTot));
            if(bytesRead >= 0)
                currentTot += bytesRead;
        } while(bytesRead > -1);
        bos.write(bytearray, 0 , currentTot);
        bos.flush();
        bos.close();
        socket.close();
    }
}

Plus, guide me how do add progress bar in it with percentage. I read about SwingWorker here but unable to implement it as I'm totally new with threading concepts. Thank you for considering my questions.

Answer 1

FileNotFoundException is something you will get if you point the File Object to some File which is not existing in that path. it means what ever the file you are trying to upload in not there in the specified path. SO make sure you give a valid path.
