From source file:com.datatorrent.lib.io.jms.JMSTestBase.java

public void produceMsg(String text) throws Exception {
    // Create a ConnectionFactory
    ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("vm://localhost");

    // Create a Connection
    Connection connection = connectionFactory.createConnection();
    connection.start();//from   w w  w  .ja  va 2  s.c  om

    // Create a Session
    Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);

    // Create the destination (Topic or Queue)
    Destination destination = session.createQueue("TEST.FOO");

    // Create a MessageProducer from the Session to the Topic or Queue
    MessageProducer producer = session.createProducer(destination);
    producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

    // Create a messages
    TextMessage message = session.createTextMessage(text);
    producer.send(message);

    // Clean up
