7.2. Simple Core Example

Here is a very simple program using the core messaging API to send and receive a message: 
ClientSessionFactory factory =  HornetQClient.createClientSessionFactory(
                                        new TransportConfiguration(
                                           InVMConnectorFactory.class.getName()));

ClientSession session = factory.createSession();

session.createQueue("example", "example", true);

ClientProducer producer = session.createProducer("example");

ClientMessage message = session.createMessage(true);

message.getBodyBuffer().writeString("Hello");

producer.send(message);

session.start();

ClientConsumer consumer = session.createConsumer("example");

ClientMessage msgReceived = consumer.receive();

System.out.println("message = " + msgReceived.getBodyBuffer().readString());

session.close();
