Migrating from WebSphere MQ to Active MQ

Question

There was a similar question Procedure to migrate from IBM MQ to ActiveMQ and it was closed, but I will try anyway. Our customers want to migrate from WebSphere MQ to Active MQ. In above mentioned question it was said that as for JMS such migration in theory will consist in apps re-configuration. Our customers say that their apps use auto-generated .bindings file. So, is it possible to make apps work with Active MQ just by editing .binding file and putting active mq's .jars to java classpath, or some other configuration is required?

Answer 1

To check this , i tried the following

a) Create a WMQ bindings file use JMSAdmin. Once i created a QCF and Queue i was able to send a message via a JMS lookup and send a message.

b) For the AMQ set up to generate a .bindings file , IBM had some sample code to generate the bindings file.

Once this was done i used exactly the same code to send a message and the message was perfectly sent to both AMQ and WMQ

Here is the sample code that i was able to interoperate.

public void sendMessages() {

        ConnectionFactory connectionFactory;
        Connection con = null;
        Session session = null;
        MessageProducer producer = null;
        //create initial context properties
        Properties initialContextProperties = new Properties();
        initialContextProperties.put("java.naming.factory.initial", "com.sun.jndi.fscontext.RefFSContextFactory");
        initialContextProperties.put(Context.PROVIDER_URL, "file:/C:/JNDI-Directory/AMQ");
        initialContextProperties.setProperty("transport.jms.security.authentication", "none");

        try {
            InitialContext initialContext = new InitialContext(initialContextProperties);
            //create connection factory object
            //ivtQCF - created connection factory object in IBM-MQ
            connectionFactory = (ConnectionFactory) initialContext.lookup("confact2");
            con = connectionFactory.createConnection();
            con.start();
            session = con.createSession(false, Session.AUTO_ACKNOWLEDGE);
            //localq - created queue in IBM-MQ
            Destination destination = (Destination) initialContext.lookup("dest");
            producer = session.createProducer(destination);
            String msg = "SAMPLE MESSAGE PLACED TO QUEUE";
            TextMessage textMessage = session.createTextMessage(msg);
            producer.send(textMessage);
            con.close();
            session.close();
            producer.close();
        } catch (NamingException e) {
            throw new RuntimeException("Unable to send jms messages", e);
        } catch (JMSException e) {
            throw new RuntimeException("Unable to send jms messages", e);
        }
    }
