Structured message reading problem in Netty.

[Dai Jun]

Hi manishr22,

I am also new to netty and not very sure of my opionion :). By using
pipeline, we should change the ChannelPipeline annotation of
DiscarServerHanlder from all to one, as shown in Timer example in
setion 1.7.2. of user guide.
BTW, would you post these runtime exceptions and client codes? I think
that will be helpful to understand your problem exactly.
