ChannelFutureProgressListener interface not working as expected!

[Fahad Kalil]

Trustin,

Thanks for the reply..
I'm using on Windows enviroment, so now I know why it's not working as
expected!

I've checked some other threads and solved my problem using the well-known
ChannelFutureListener interface.

Bye,
Fahad
