Here's some code I use to send a file from a Java server to a Delphi client,
though it will work to send a file to a client written in any language
(assuming the client is implemented in a compatible manner):

                    BufferedOutputStream binOutput = new
BufferedOutputStream(socket.getOutputStream());
                    FileInputStream inputStream = new
FileInputStream(fileName); // read in the file
                    int numBytes = inputStream.available();
                    int bytesRead = 0;
                    while (bytesRead < numBytes)
                    {
                        int currBytesRead = inputStream.read(fileBuffer);
                        bytesRead += currBytesRead;
                        binOutput.write(fileBuffer, 0, currBytesRead);
                        binOutput.flush();
                    }
/* I use three 255 chars to signal to the client that the file is done.  I
am not sure if this works in all cases, but I have never had any problems
with it.  */
                    for (int i = 0; i < 3; i++)
                        binOutput.write(255);
                    binOutput.flush();


As I said, this is just the sending side.  I have never implemented the
receiving part in Java, though it would follow roughly the same logic.  See
the java.io package to pick which stream classes to use (probably some sort
f BufferedInputStream).
