I think this code is working only on localhost, becuase you send the
serialized File object and not the content of file. The serialized File
object contain the path of file, so the length is correct. You must write
the content of file to IoSession. You can use FileChannel to load files to
ByteBuffer (the code is an example only, I don't tested this):
* File file = new File("any file name");
> FileInputStream fis = new FileInputStream(file);
> FileChannel channel = fis.getChannel();
> long readed = 0;
> while(readed != file.length()){
> ByteBuffer buffer = channel.map(MapMode.READ_ONLY, 0,
> 1024);
> buffer.rewind();
> readed += buffer.limit();
> session.write(buffer);
> } *
