Structured message reading problem in Netty.

[Trustin Lee]

Hi Manish,

Looking from your code, you don't have a FrameDecoder or
ReplayingDecoder in a pipeline, which means you have a good chance to
receive only partial data, which leads to IndexOutOfBoundsException.
Did you have a chance to read the first chapter of the user guide?
There's good amount of explanation about this issue there.

You and other community members have exchanged quite a lot of
questions and answers so far.  My impression so far is that you just
want people to fix your code.  We could solve your problem just by
writing the fixed code for you, but it would be much better for you to
follow all the step demonstrated in the user guide.  Then you will
know what is wrong with your current code very easily.

Also, you might find the factorial example more useful than the
discard example for your case.
