I am an ActiveMQ begginer. My main looks like this:
public static void main(String[] args) throws Exception {
BrokerService broker = new BrokerService();
if(isProducer(args)){
broker.addConnector("tcp://localhost:8001");
broker.start();
// start producer...
}
else{
broker.addConnector("tcp://localhost:9000");
broker.addNetworkConnector("static:(tcp://localhost:8001)");
broker.start(); // Getting stuck here!!!
// start consumer
}
waitForever();
}
I start this application twice, once a a producer and once as a consumer. When I start the consumer, it gets stuck on the broker.start() line.
What am I missing?!
Basicly you start the broker once (embedding it into a jvm).
BrokerService broker = new BrokerService();
broker.setUseJmx(true);
broker.addConnector("tcp://localhost:61616");
broker.start();
Then you connect to the broker (this code is needed in both consumer and producer application):
url = "vm://localhost:61616" //if you are in same jvm
url2 = "tcp://localhost:61616" //if you are in diff jvm or other host
connectionFactory = new ActiveMQConnectionFactory(username,password,url);
connection = (ActiveMQConnection) connectionFactory.createConnection();
connection.start();
session = connection.createSession(transacted, ackMode);
Then setup a consumer
Destination queue = session.createQueue("queuename");
MessageConsumer consumer = session.createConsumer(queue);
consumer.setMessageListener(new MessageConsumer());
Setup a producer and send a message
MessageProducer producer = session.createProducer(queue);
ObjectMessage objectMessage = session.createObjectMessage();
objectMessage.setObject(object);
producer.send(objectMessage);
