[rabbitmq-discuss] How to configure reply queue?

[Rajasekhar P]

Hi Russell,

Here is the my listerner POJO , still am getting null response. I didnt do
any reply queue/corrID configuration.

      // receive messages
public Object handleMessage(String query) {
Test test = new Test("Pandit", "Pillai");
return test;
}

Producer -

Test response = (Test)this.rabbitTemplate.convertSendAndReceive(msg);
System.out.println("Response : " + response);

Result -
*Response : null*


Could you please help me . Thanks in advance.
