Would anyone please suggest me a solution to send/receive a large

clueless.

300 KB is not large.

What have you tried ?

It is relative straightforward.

Below is attached a very simple example.

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

public class Server {
    public static void main(String[] args) throws Exception {
       ServerSocket ss = new ServerSocket(9999);
       Socket s = ss.accept();
       InputStream is = s.getInputStream();
       OutputStream os = new FileOutputStream("C:\\z2.zip");
       byte[] b = new byte[10000];
       int n;
       while((n = is.read(b)) >= 0) {
          os.write(b, 0, n);
       }
       os.close();
       is.close();
    }
}

import java.net.*;

public class Client {
    public static void main(String[] args) throws Exception {
       Socket s = new Socket("localhost", 9999);
       OutputStream os = s.getOutputStream();
       InputStream is = new FileInputStream("C:\\z1.zip");
       byte[] b = new byte[10000];
       int n;
       while((n = is.read(b)) >= 0) {
          os.write(b, 0, n);
       }
       os.close();
       is.close();
    }
