Problems transferring multiple files

Question

I'm trying to write a program to transfer multiple files from a client to a server, but I'm having trouble getting the server to distinguish between them.
I have tried both buffered streams, and straight input/output streams, and in both cases, the server doesn't seem to get any EOF, and keeps reading all data it reads into the first file. I can't figure out why EOF is never read (ie: ((read = bis.read(buffer)) != -1) never evaluates to -1). Can anybody see why that might be?
Client:
buffer = new byte[16384];
out    = serverSocket.getOutputStream();
bos    = new BufferedOutputStream(out);
objOut = new ObjectOutputStream(out);
objOut.writeInt(file.length);  // # of files to transfer
for (int i=0; i<file.length; i++) {
    try {
        fileIn = new FileInputStream(file.getAbsolutePath());
objOut.writeLong(file[i].length()); // file length (for dirty CRC check)
objOut.writeObject(file[i].getName()); // file name
objOut.flush(); // because otherwise the server hangs waiting
while ((read = fileIn.read(buffer)) > 0) {
bos.write(buffer, 0, read);
bos.flush();
catch (Exception e) {}
Server:
in = socket.getInputStream();
objIn = new ObjectInputStream(in);
bis = new BufferedInputStream(in);
fileCnt = objIn.readInt();  // # of files to be transferred
for (int i=0; i<fileCnt; i++) {
    totalLen = objIn.readLong();  // file length
    try { fileName = (String)objIn.readObject(); }  // file name
    catch (Exception e) {}
    try { toFile = new FileOutputStream(new File(fileName)); }
    catch (FileNotFoundException ex) {}
    while ((read = bis.read(buffer)) != -1) {
        toFile.write(buffer, 0, read);

Answer 1

the problem is you are not stoping the writing to file when you hit the end of one file.
At the server you should count the number of bytes that you write to the disk and should stop when the total count reach the file size.
Or you have to completly change your protocole to handle entire file as one unit.
Ex:-
public class MyFile implements java.io.Serializable{
String path;
private void writeObject(ObjectOutputStream oos){
   oos.defaultWriteObject();
   byte b[] = new byte[1024*128];
   int i = 0;
   FileInputStream fis = new FileInputStream(path);
   while ((i = fis.read(b)) >=0){
      oos.writeObject(trim(b,i));
   fis.close();
   oos.writeObject("EOF");
private byte[] trim(byte b[], int i){
    byte b2[] = new byte;
System.arraycopy(b,0,b2,0,i);
return b2;
// You should be able to write the read object method
