I want the Bytes opened as Bytes not Characters ?

Question

Hi,
Here is my assignment main points:
1. Get File:
I use file = fd.getSelectedFile(); to get the file content, and
String filename = file.getName(); to get the file name
Two things must be sent to the Server; the file name and the file content.
2. Sending the file to Server:
//Get a reference to the socket's output streams
DataOutputStream os = new DataOutputStream(socket.getOutputStream());
//Opens the requested file.
FileInputStream fis = null;
boolean fileExists = true;
try {
fis = new FileInputStream(file);
} catch (FileNotFoundException e) {
fileExists = false;
if (fileExists)
//Construct a 1K buffer to hold the bytes on their way to the socket
byte[] buffer= new byte[1024];
int bytes = 0;
//Copy requested file into the socket's output stream.
while((bytes = fis.read(buffer)) != -1)
os.write(buffer, 0, bytes);
// Close the file
fis.close();
*The file has been sent to the Server as a Byte Buffers through DataOutputStream
3. Open the file in Server side:
// Receive the file
InputStream is = client.getInputStream();
BufferedReader breader = new BufferedReader( new InputStreamReader(is));
// Read the file as String
String line;
StringBuffer builder = new StringBuffer();
while ( (line = breader.readLine()) != null){
builder.append(line);
builder.append(" ");
String text = builder.toString();
*The file has been opened as a text .
4. Print the File:
printText( text );
The file has been printed as a text .
Problems I faced are:
1. I dont know how to send the file name + file content, now I can just send the content of the file, I know that some modification must be done in 2. Sending the file to Server, but I don't know how?
2. I dont want to recieve the file in Server side as text, instead I want to recieve it as a bytes so I can print any type of file, how to do that?
Any Advice? or sample code ?
Thanks in advance.

I don't see the problem. Use DataOutputStream's writeUTF and DataInputStream's
readUTF for the filename and write and read bytes for the filecontent. Don't
use Readers or Writers.
