WSO2 ESB AMQ Connection Error

Question

I am working with WSO2 ESB 4.7.0 and WSO2 MB 2.2.0.

I want to work with the concepts of publish and subscribe messages with JMS queues. For this I have made integration between WSO2 ESB and WSO2 MB by following the below link:

https://docs.wso2.com/display/MB220/Integrating+WSO2+ESB

I have followed all the steps mentioned in the document and tried to restart the ESB server but failed to start the server cause of the below error:

AMQConnection Unable to connect to broker at tcp://localhost:5672

How to overcome this error and start the ESB server successfully?

Need any further configuration in any of the files present in ESB.

This could be a port configuration issue.

The tutorial is mentioning to set the port of the two connection factories to 5673 in the JDNI.properties file of the ESB after applying a port offset for the Message Broker, yet you are getting an exception on port 5672 when trying to connect to the Message Broker. Make sure the two match.

In the Message Broker logs you should see something like this if you set the port offset to 1:

INFO {qpid.message.broker.listening} -  [Broker] BRK-1002 : Starting : Listening on TCP port 5673
