Hello @arthirajan , Can you pl add a line summarizing your issue? Are you getting this as an JMSException? Are you looking for explanation of this log?
I assume you are trying to create the same queue each time you start a new connection with session.createQueue(). This will get 400 response from broker for all but the first attempt. You can simply log this and continue.
FYI, typically, queue creation is an administrative activity done once. In this model, an administrator creates the queue and the application does JNDI lookup.
A sample implementation is here:
Obtaining JMS objects using JNDI.
