How to communicate with TIBCO EMS Server using Loadrunner?

Question

I am new to TIBCO and trying to communicate with EMS Server using loadrunner.

The communication between the client and server takes place generally over TCP.

I have following details with me:

URL: tcp://someserver.com:port
Username:
Password:
Queue Connection Factory: QueueConnectionFactory

Did any one try publishing messages on EMS Server with Loadrunner.

Please suggest on how can I start scripting?

Did you *try* anything ? Please show any research effort you made on this question — Rafalon, Oct 16 '17 at 08:58
i tried using soap request and imported xml(mesg), but it shows only endpoint url, where can i provide the target queue name? — Neha, Oct 16 '17 at 09:47
I dont know whether doing a soap request is a good approach.just trying. — Neha, Oct 16 '17 at 09:48
Can i use JMS protocol to send message to EMS as it is the extension to JMS — Neha, Oct 16 '17 at 10:20

I believe you should be using tibjmsnaming:// not tcp. and Keep the needed JMS/EMS libraries available in the Path.

you should be using WebServices template. I remember publishing messages to Load runner long back.

You have a number of paths to any JMS compliant target. Some use web services protocol. My preference is a small Java template virtual user leveraging the appropriate connection factory elements. Very likely your queue solution also has a C level interface which could be incorporated into a C template virtual user. You have options for a virtual user developed in Visual Studio (see documentation, advanced topics) using C++/C#/VB. If you have an existing client you may even be able to record a "push" and a "pop" from the queues with Winsock and manipulate the appropriate buffers for exercise - I have used this path with MQ in the past.

So, lots of options based upon your skills, your licensed virtual user types, etc...

After searching it on google and trying out with different protocols, i found out a simple way to publish message on EMS server.
As EMS is an extension of JMS(java messaging service) we have to use jms protocol to communicate with EMS.
Using a java vuser in VUGEN is the best option.
Below is the code you can paste in actions.java file.

public int action() throws Throwable {
        String serverUrl = "tcp://localhost:7222";
        String userName = "admin";
        String password = "admin";

        String queueName = "your queue name";

        try {
        System.out.println("Sending JMS message to server " + serverUrl + "...");

        QueueConnectionFactory factory = new TibjmsQueueConnectionFactory(serverUrl);
        QueueConnection connection = factory.createQueueConnection(userName, password);
        QueueSession session = connection.createQueueSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);

        // Use createQueue() to enable sending into dynamic queues.
        Queue senderQueue = session.createQueue(queueName);
        QueueSender sender = session.createSender(senderQueue);

        /* publish messages */

        TextMessage jmsMessage = session.createTextMessage("your message");
        //String text = (String) data.elementAt(i);
        //jmsMessage.setText(text);
        sender.send(jmsMessage);
        System.out.println("Sent message!");


        connection.close();
        } catch (JMSException e) {
        e.printStackTrace();
        System.exit(0);
    }
        return 0;
}//end of action

It's an old question but I found this snippet very helpful, thanks. Unfortunately, I keep on getting a compiling error on several lines, like following, maybe you can help again, I would really appreciate: `/Actions.java:29: error: cannot find symbol QueueConnectionFactory factory = new TibjmsQueueConnectionFactory(serverUrl);` — twinge, Nov 24 '21 at 16:27
I answer myself :) Those imports were missing: `import javax.jms.*; import com.tibco.tibjms.*;` — twinge, Nov 25 '21 at 15:55
