HTTP Web Server

Question

Hi!
I have to make an http web server: in a browser, I write http://ServerName:port/file and the browser must display the file. The only problem now seems to be that I changed
This line gets the OutputStream of the client socket
out = new PrintWriter(new OutputStreamWriter(scliente.getOutputStream(),"8859_1"),true) ;And this thing sends the response to the browser:
out.println("HTTP/0.9 200 ok");
                out.println("Server: Nombre del Servidor/1.0");
                out.println("Date: " + new Date());
                out.println("Content-Type: text/html");
                out.println("Content-Length: " + file.length());
                out.println(System.getProperty("line.separator"));
                BufferedReader localFile= new BufferedReader(new FileReader(archivo));
                String line= "";
                do         
                    line = localFile.readLine();
                    if (line != null )
                        // sleep(500);
                        out.println(line);
                while (linea!= null);The thing is... That didn't work for displaying images and other file types, which is why I changed the previous code to:
out = scliente.getOutputStream();And the other part to:
byte[] contenido;
                int tamano;
                escribirEnCliente("HTTP/1.1 200 ok");
                escribirEnCliente("Server: Nombre del Servidor/1.0");
                escribirEnCliente("Date: " + new Date());
                escribirEnCliente("Content-Type: " + new MimetypesFileTypeMap().getContentType(archivo));
                escribirEnCliente("Content-Length: " + archivo.length());
                FileInputStream archivoLocal = new FileInputStream(archivo);
                tamano = archivoLocal.available();
                contenido = new byte[tamano];
                do         
                  tamano = archivoLocal.read(contenido);
                  out.write(contenido);
                while (tamano != -1);escribir en cliente is a procedure like this:
public void escribirEnCliente(String str)
            out.write(str.getBytes("8859_1"));
}This way, I thought, I could send all types of files, not only text files. But it doesn't work, it doesn't even load the page. Any suggestions?

...and in your do/while loop think what happens when read() does return -1. You still write the entire buffer. You should do something like this instead:
    while (true) {
        int count = in.read(buf);
        if (count == -1)
            break;
       out.write(buf, 0, count);
    }
