Unable to access ActiveMQ using JMS based code and amqp 1.0

Question

I'm trying to connect to an ActiveMQ broker using AMQP 1.0, but I want to use JMS within my application code. I'm interested in using JMS primarily because I want developers to be able to use API's that they are already familiar with.

I have ActiveMQ 5.14.0 running on localhost and the following code :

    public static void main(String[] args) throws JMSException, InterruptedException {

    Connection connection = null;
    try {
        // Producer
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("amqp://localhost:5672");

        connection = connectionFactory.createConnection();
        connection.start();     

        Session session = connection.createSession(false,
                                                   Session.AUTO_ACKNOWLEDGE);

        Topic topic = session.createTopic("customerTopic");     

        // Publish
        MessageProducer producer = session.createProducer(topic);
        for ( int i = 0; i < 10; i++) {
            Message msg = session.createTextMessage("Task : " + i);

            producer.send(msg);

        }
        session.close();
    } finally {
        if (connection != null) {
            connection.close();
        }

    }


}

The code always fails in the same way, with the following root cause in the stacktrace :

Caused by: org.apache.activemq.transport.InactivityIOException: Channel was inactive for too (>30000) long: tcp://127.0.0.1:5672

This happens on the connection.start() method call.

If I run the same code against the ActiveMQ tcp endpoint then it executes as expected.

My pom file dependencies are as follows ( and I suspect that this is the root of my problem as I find the documentation of dependencies extremely hard to follow )

<dependencies>
    <dependency>
        <groupId>org.apache.qpid</groupId>
        <artifactId>qpid-amqp-1-0-client-jms</artifactId>
        <version>0.32</version>
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-amqp</artifactId>
        <version>5.14.0</version>
    </dependency>

</dependencies>

My immediate question is "Why doesn't this work?".

My supplementary ( opinion based ) question is "Is it worthwhile trying to use the JMS abstraction above AMQP 1.0, or should I just abandon myself to learning the provider specific APIs?"

Answer 1

it is better to work with jndi

public static void main(String[] args) throws JMSException, InterruptedException, NamingException {
    Connection connection = null;
    try {
        Properties props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.qpid.jms.jndi.JmsInitialContextFactory");
        props.setProperty("connectionfactory.myFactoryLookup",
                "amqp://localhost:5672");
        props.put("topic." + "MyTOPIC", "customerTopic");
        InitialContext ic = new InitialContext(props);
        ConnectionFactory cf1 = (ConnectionFactory) ic.lookup("myFactoryLookup");
        Topic topic = (Topic) ic.lookup("MyTOPIC");
        connection = cf1.createConnection();
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        MessageProducer producer = session.createProducer(topic);
        connection.start();
        for (int i = 0; i < 10; i++) {
            Message msg = session.createTextMessage("Task : " + i);
            producer.send(msg);
        }
        session.close();
    } finally {
        if (connection != null) {
            connection.close();
        }
    }
}

replace

 <dependency>
    <groupId>org.apache.qpid</groupId>
    <artifactId>qpid-amqp-1-0-client-jms</artifactId>
    <version>0.32</version>
</dependency>

by

    <dependency>
        <groupId>org.apache.qpid</groupId>
        <artifactId>qpid-jms-client</artifactId>
        <version>0.9.0</version>
    </dependency>

on the broker side you need to add:

 <transportConnector name="amqp" uri="amqp://0.0.0.0:5672?transport.transformer=jms"/>
