Download AMQ-standalone_test_program.zip. topic-receive.cpp is used as receiver to the topic. Run AMQ 7.8 instance. Publisher and Subscribers are also running in same host as broker. Publisher is using core protocol while C++ subscribers are amqp. Compile topic-receive.cpp $ g++ topic-receive.cpp -lqpid-proton-cpp -o topic-receive.out From two different terminal run two subscribers $ ./topic-receive.out RECEIVE: Opened receiver for source address 'exampleTopic' We should get  two subscribers to address exampleTopic. $ ./artemis queue stat|grep exampleTopic |0e92a161-75a1-4056-82ea-1fd36d13c31c|exampleTopic |1 |0 |0 |0 |0 |0 |MULTICAST | |d204890a-ef13-4acc-8544-102d94c04911|exampleTopic |1 |0 |0 |0 |0 |0 |MULTICAST |  Run Publisher.java from AMQ-standalone_test_program with arguments "admin localhost".
