If you have not already done so, prepare the broker distribution before running the example.
To run the example, simply type mvn verify from this directory, or mvn -PnoServer verify if you want to start and create the broker manually.
This example shows you how to use a QueueRequestor with ActiveMQ Artemis.
JMS is mainly used to send messages asynchronously so that the producer of a message is not waiting for the result of the message consumption. However, there are cases where it is necessary to have a synchronous behavior: the code sending a message requires a reply for this message before continuing its execution. A QueueRequestor facilitates this use case by providing a simple request/reply abstraction on top of JMS.
The example consists in two classes:
TextReverserService: A JMS MessageListener which consumes text messages and sends replies containing the reversed text.
QueueRequestorExample: A JMS Client which uses a QueueRequestor to send text requests to a queue and receive replies with the reversed text in a synchronous fashion.
