Ron,
How big is your buffer? Where do you manage offset and byte count?
You don't check what values did DataInputStream.read() returned.
You have to do a bit more management in order to read the whole file
into a byte array. Just google for 'reading a whole file in Java' or
better still 'copying files in Java'. That should show you, what needs
doing around buffers, offsets etc.
