Problem send long to client connected with DatagramAcceptor

Hello,

I'm trying to send a CRC checksum back to a client connected to my 
server throguh a DatagramAcceptor using the following:

long crc = 1234;
ByteBuffer writeBuffer = ByteBuffer.allocate(8);
writeBuffer.putLong(0, crc);
session.write(writeBuffer, null);

The client (written in C) receives 8 bytes as expected, however the 
receive buffer is empty.

Any suggestions?

Cheers,
Cameron Ross.

 You forgot to flip your buffer before writing it. :)
 Thanks,
