Example 2 with QueueRequestor

use of javax.jms.QueueRequestor in project activemq-artemis by apache.

the class QueueRequestorExample method main.

public static void main(final String[] args) throws Exception {
    QueueConnection connection = null;
    InitialContext initialContext = null;
    try {
        // Step 1. Create an initial context to perform the JNDI lookup.
        initialContext = new InitialContext();
        // Step 2. Perfom a lookup on the queue
        Queue queue = (Queue) initialContext.lookup("queue/exampleQueue");
        // Step 3. Look-up the JMS queue connection factory
        QueueConnectionFactory cf = (QueueConnectionFactory) initialContext.lookup("ConnectionFactory");
        // Step 4. Create a TextReverserService which consumes messages from the queue and sends message with reversed
        // text
        TextReverserService reverserService = new TextReverserService(cf, queue);
        // Step 5. Create a JMS QueueConnection
        connection = cf.createQueueConnection();
        // Step 6. Start the connection
        connection.start();
        // Step 7. Create a JMS queue session with AUTO_ACKNOWLEDGE mode
        QueueSession session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
        // Step 8. Create a JMS queue requestor to send requests to the queue
        QueueRequestor queueRequestor = new QueueRequestor(session, queue);
        // Step 9. Create a JMS message to send as a request
        TextMessage request = session.createTextMessage("Hello, World!");
        // Step 10. Use the requestor to send the request and wait to receive a reply
        TextMessage reply = (TextMessage) queueRequestor.request(request);
        // Step 11. The reply's text contains the reversed request's text
        System.out.println("Send request: " + request.getText());
        System.out.println("Received reply:" + reply.getText());
        // Step.12 close the queue requestor

        reverserService.close();
    } finally {

            try {
                // Step 14. Be sure to close the JMS resources!
