Proton qpid java example

ActiveMQ is a multi protocol broker. It will inspect the initial handshake of clients to determine what protocol to use.

All you need to do is to connect a client into activemq's configured port and you should be able connect.

To run this example simply run the command mvn verify -Pexample, execute the compile.sh script and start the executable called ./hello

You don't need to do anything special to configure the ActiveMQ server to accept AMQP clients.

Just for the sake of documentation though we are setting the port of ActiveMQ on this example as 5672 which is the port qpid have by default.

This is totally optional and you don't need to follow this convention. You can use any port you chose including ActiveMQ's 61616 default port

     
         <acceptor name="proton-acceptor">tcp://localhost:5672</acceptor>
     
     

Example step-by-step

1. Create an amqp qpid 1.0 connection.

           connection= new Connection("localhost", 5672, null, null);
        

2. Create a session

           Session session = connection.createSession();
        

3. Create a sender

           Sender sender = session.createSender("testQueue");
        

4. send a simple message

           sender.send(new Message("I am an amqp message"));
        

5. create a moving receiver, this means the message will be removed from the queue

           Receiver rec = session.createMovingReceiver("testQueue");
        

6. set some credit so we can receive

          rec.setCredit(UnsignedInteger.valueOf(1), false);
        

7. receive the simple message

          Message m = rec.receive(5000);
                System.out.println("message = " + m.getPayload());
        

8. acknowledge the message

          rec.acknowledge(m);
        

9. close the connection

          connection.close();
