[rabbitmq-discuss] Issue in Java client while fetching channel

Wed Aug 5 02:24:44 BST 2009

Ben,

As per the java client documentation, channel is not thread safe and I have multiple threads that would publish messages to the Q. For each publish, I create a new channel and publish the message. 

Earlier I was not closing the channel and this lead to connection.createChannel() returning null object. Now as per java client document again, it is stated that if there are no channels available or if the current channel number is currently in use, then it would return null. Hence now I have closed the channel after each publish.

If you are aware of any other case where we may end up getting a null channel, then please let me know.

Why do have to close the channel after you publish each message?
