[FIXED] Tomcat failing to communicate with Artemis MQ

Issue

I wanted to schedule a message delay using JMS. For that I'm using JMS 2.0 with Artemis MQ and the message is scheduled successfully in compile time but when I deploy it in Tomcat and try to send the message with a delay it says:

java.lang.IllegalStateException: setDeliveryDelay requires JMS 2.0

I'm guessing that the Tomcat isn't able to communicate properly with the Artemis server I have setup. So I have two servers setup in my system: Tomcat and Artemis. Is it because Tomcat can't communicate with Artemis? If so, then why does my spring boot in-built Tomcat server detects Artemis but my standalone Tomcat doesn't?

My source code for the JMS message sender is:

@Service
public class TransferServiceImpl implements TransferService {

    @Autowired
    private JmsTemplate jmsTemplate;

    @Override
    public void transfertoJMS(Transaction transaction) {
        System.out.println("Sending a transaction.");

        jmsTemplate.setDeliveryDelay(20000);
        jmsTemplate.convertAndSend(destinationQueue, transaction);
    }
}

My pom.xml is:

Solution

You've got a conflict with two conflicting dependencies. The following dependency is for ActiveMQ 5.x(!):

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-broker</artifactId>
</dependency>

Spring is probably finding the JMS 1.0 spec from that dependency which is overriding the JMS 2.0 spec on your classpath and giving you that java.lang.IllegalStateException when spring looks for the necessary JMS interface to use when starting up the ConnectionFactory.

If you want an embedded broker, the spring-boot-starter-artemis already contains it, so you should be able to remove that activemq-broker dependency without a problem.
