Hi All,

I’m looking for pointers to drop/publish a message to a Queue using JMS from AEM 6.5.

I referred an old post, but that doesn’t help- https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/jms-client-in-aem-using-weblogic-intialcontext/m-p/191107

Can anyone provide me input here?

Thanks,

Raju.

Hi,

Can you elaborate on what you are trying to accomplish? I am under the impression that you could use alternatives such as Sling Jobs https://techrevel.blog/2023/11/06/enhancing-efficiency-and-reliability-by-sling-jobs/

Check these for now:

Hi all,

I did figure out the way to integrate JMS with AEM as a Client application.

The first challenge was finding the right dependencies, after a struggle I managed to get the required jar files and created OSGI bundles out of those with few Import/Export packages changes.

Below is the dependent jars

<dependency>
    <groupId>com.ibm.mq</groupId>
    <artifactId>com.ibm.mq.allclient</artifactId>
    <version>9.4.1.0</version>
</dependency>
<dependency>
    <groupId>javax.jms</groupId>
    <artifactId>javax.jms-api</artifactId>
    <version>2.0.1</version>
</dependency>

Sample code to make a connection and post a message from our application.

The MQ Queue related details used in below code are from different team (they work on MQ Queue server side).

public class JmsMwssage {

    // Create variables for the connection to MQ
    //private static final String HOST = "_YOUR_HOSTNAME_"; // Host name or IP address
    private static  String HOST = ""; // Host name or IP address
    private static  int PORT = 0; // Listener port for your queue manager
    private static  String CHANNEL = ""; // Channel name
    private static  String QMGR = ""; // Queue manager name
    private static  String APP_USER = ""; // User name that application uses to connect to MQ
    private static  String APP_PASSWORD = ""; // Password that the application uses to connect to MQ
    private static  String QUEUE_NAME = ""; // Queue that the application uses to put and get messages to and from


    //public static void main(String[] args) {
    public static void sendMessage() {
        //Values from OSGI config
        HOST = “”;//Fetch your values from Config.
        PORT=“”;//Fetch your values from Config.
        CHANNEL=“”;//Fetch your values from Config
        QMGR=“”;//Fetch your values from Config
        // Variables
        JMSContext context = null;
        Destination destination = null;
        JMSProducer producer = null;

        try {
            // Create a connection factory
            JmsFactoryFactory ff = JmsFactoryFactory.getInstance(WMQ_PROVIDER);
            JmsConnectionFactory cf = ff.createConnectionFactory();

            // Set the properties
            cf.setStringProperty(WMQConstants.WMQ_HOST_NAME, HOST);
            cf.setIntProperty(WMQConstants.WMQ_PORT, PORT);
            cf.setStringProperty(WMQConstants.WMQ_CHANNEL, CHANNEL);
            cf.setIntProperty(WMQConstants.WMQ_CONNECTION_MODE, WMQConstants.WMQ_CM_CLIENT);
            cf.setStringProperty(WMQConstants.WMQ_QUEUE_MANAGER, QMGR);
            cf.setStringProperty(WMQConstants.WMQ_APPLICATIONNAME, "JmsPutGet (JMS)");
            cf.setBooleanProperty(WMQConstants.USER_AUTHENTICATION_MQCSP, true);
            cf.setStringProperty(WMQConstants.USERID, APP_USER);
            cf.setStringProperty(WMQConstants.PASSWORD, APP_PASSWORD);
            // Create JMS objects
            context = cf.createContext();
            destination = context.createQueue("queue:///" + QUEUE_NAME);
            producer = context.createProducer();
            producer.send(destination, message);
            System.out.println("Sent message:\n" + message);

            context.close();

        } catch (JMSException jmsex) {
            //Log your Exception here
        }
    }
}

Thanks,

Raju.
