[rabbitmq-discuss] How to reuse and existing connection but have different channel

[cw storm]

I've added the channel.setConfirmListener(new ConfirmListener() and
imported com.rabbitmq.client.ConfirmListener but during java compilation,
it complains :

cannot find symbol
symbol  : method setConfirmListener(<anonymous
com.rabbitmq.client.ConfirmListener>)
location: interface com.rabbitmq.client.Channel
channel.setConfirmListener(new ConfirmListener()
