Java EE: Sending messages to a message queue

Sending messages to a JMS queue consists of injecting a few resources to our code and making a few simple JMS API calls. The following example illustrates how to add messages to a message queue:

import javax.annotation.Resource;

import javax.jms.ConnectionFactory;

import javax.jms.JMSContext;

import javax.jms.JMSProducer;

import javax.jms.Queue;

public class MessageSender {

@Resource(mappedName = "jms/GlassFishBookConnectionFactory")

private static ConnectionFactory connectionFactory;

@Resource(mappedName = "jms/GlassFishBookQueue")

private static Queue queue;

public void produceMessages() {

JMSContext jmsContext = connectionFactory.createContext();

JMSProducer jmsProducer = jmsContext.createProducer();

String msg1 = "Testing, 1, 2, 3. Can you hear me?";

String msg2 = "Do you copy?";

String msg3 = "Good bye!";

System.out.println("Sending the following message: "

+ msg1);

jmsProducer.send(queue, msg1);

System.out.println("Sending the following message: "

+ msg2);

jmsProducer.send(queue, msg2);

System.out.println("Sending the following message: "

+ msg3);

jmsProducer.send(queue, msg3);

}

}
