Problem when trying to switch from netty to ZeroMQ( java.lang.ClassNotFoundException: backtype.storm.messaging.zmq)

[Sajith]

Hi all,

I'm trying to switch from netty yo ZeroMQ and my storm version is
0.9.2-SNAPSHOT. I copied zmq.jar to STORM_HOME/lib and the necessary libs
into /usr/local/lib. Then I sent storm.messaging.transport:
"backtype.storm.messaging.zmq"  in storm.yaml. But i still get the
following error when I submit a topology,

2014-05-05 01:58:41 b.s.d.worker [ERROR] Error on initialization of server

Can someone please tell me what have gone wrong or point me to a reference
on the correct way for switching the transport.
