Hi Devs,
When publishing to RabbitMQ from WSO2 EI 6.1.1 [1], if the queue size is
reached (RabbitMQ Publisher Confirms) then it throws an exception in EI. As
per [2], this throws an axis2 exception, but in the fault sequence, the
error code is 0 as [3]. Since the error code is not defined, is there a way
to differentiate the nacks when publishing messages to queue?
[1] -
<call>
<endpoint name="EP-Queue-Confirm" xmlns="http://ws.apache.org/ns/synapse
">
<address uri="rabbitmq:/AMQPProducer?rabbitmq.server.host.name
=localhost&rabbitmq.server.port=5672&rabbitmq.queue.name
=Q-SampleEsb&rabbitmq.queue.route.key=R-SampleEsb&
rabbitmq.exchange.name=Ex-SampleEsb&*rabbitmq.confirm.delivery=true*"/>
</endpoint>
</call>
