Problem with Sending files over Sockets

Question

Hi. I have a problem when I try to send files over sockets. When I send text files it works well but when I try to send .jpg or other kind of files it doesn't work well because some characters are wrong, I hope you can help me.
Here is my code:
//Sender code
import java.io.*;
import java.net.*;
class Servidor{
     Servidor(){
          try{
               String arch="art.jpg";
               ServerSocket serv=new ServerSocket(125);
               Socket socket=serv.accept();
               System.out.println("Conectado");
               int c;
               BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
               FileInputStream fis=new FileInputStream(arch);
               File f=new File(arch);
               bw.write(""+f.length());
               bw.newLine();
               bw.flush();
               System.out.println("Escribiendo");
               while((c=fis.read())!=-1){
                    bw.write(c);
               bw.flush();
               fis.close();
               System.out.println("Terminado");
               while(true){
          }catch(Exception e){
               System.out.println(e);
     public static void main(String arg[]){
          new Servidor();
//Client code
import java.io.*;
import java.net.*;
class Cliente{
     Cliente(){
          try{
               Socket socket=new Socket("localhost",125);
               System.out.println("Conectado");
               BufferedReader br=new BufferedReader(new InputStreamReader(socket.getInputStream()));
               long tam=Long.parseLong(br.readLine());
               long act=0;
               FileOutputStream fos=new FileOutputStream("resp.jpg");
               System.out.println("Recibiendo: "+tam);
               while(act<tam){
                    fos.write(br.read());
                    act++;
               System.out.println("Terminado: "+act+" / "+tam);
               fos.close();
          }catch(Exception e){
               System.out.println(e);
     public static void main(String arg[]){
          new Cliente();
}

I don't think you want BufferedReader and OutputStreamWriter, you want ByteArrayOutputStream and ByteArrayInputStream . The problem is that you are sending jpegs (binary data) as text.
