Hi there, do any of you guys have a groovy script that works with jms and Websphere MQ?   I'm struggling with the concept..   Regards SP

    Hi  Stephanus,

     

    Please see my comments:

    >> If I open JMS (Configure JMS) I press green arrow on the configs, I get no message so I think its working.

    You should have the message that the Connection successfully tested. 

     

     

    >> Do you have a groovy script that I can use with HermesJMS?

    The script from the Working With JMS From Groovy Scripts article works for the WebSphere provider too, you just need to change the jmsEndpoint value.

     

    import com.eviware.soapui.impl.wsdl.submit.transports.jms.JMSConnectionHolder
import com.eviware.soapui.impl.wsdl.submit.transports.jms.util.HermesUtils
import com.eviware.soapui.impl.wsdl.submit.transports.jms.JMSEndpoint
import hermes.Hermes
import javax.jms.*


//Establishing the JMS connection
def jmsEndpoint = new JMSEndpoint("jms://activeMQSession::queue_testQ1::queue_testQ1");
def hermes = HermesUtils.getHermes( context.testCase.testSuite.project, jmsEndpoint.sessionName)
def jmsConnectionHolder = new JMSConnectionHolder( jmsEndpoint, hermes, false, null, null, null);

// Obtaining the session and queue
Session queueSession = jmsConnectionHolder.getSession();
Queue queueSend = jmsConnectionHolder.getQueue( jmsConnectionHolder.getJmsEndpoint().getSend() );
Queue queueBrowse = jmsConnectionHolder.getQueue( jmsConnectionHolder.getJmsEndpoint().getReceive() );

// Performing some actions
MessageProducer messageProducer = queueSession.createProducer( queueSend );
TextMessage textMessageSend = queueSession.createTextMessage();
textMessageSend.setText( "A JMS message sent from ReadyAPI.");
messageProducer.send( textMessageSend );
textMessageSend.setText( "Another JMS message sent from ReadyAPI.");
messageProducer.send( textMessageSend );

// Logging elements
QueueBrowser qb = queueSession.createBrowser(queueBrowse);
Enumeration en = qb.getEnumeration();
while(en.hasMoreElements())
{
    TextMessage tm = (TextMessage)en.nextElement();
    log.info tm.getText()
}
jmsConnectionHolder.closeAll() // Make sure to close the session and connection

     

    >> If I want to as JMS Destination to project I 'm getting an error. Check the Error attached.
    This error occurs when the session isn't properly configured in HermesJMS.

     

    >> I also added the Hermes JMS screen to show that it works with the config file.

    Can you see the queues content in HermesJMS for the configured session: https://www.screencast.com/t/xuQK0QtFlDC

     

    You can also open a new support case here: https://support.smartbear.com/message/?prod=ReadyAPI

Hi Stephanus,

 

Thank you for your post! Please find the sample script which sends a message:

import javax.jms.*
import java.util.Properties
import javax.naming.Context
import javax.naming.InitialContext

Properties props = new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
props.setProperty(Context.PROVIDER_URL, "file:/D:/Practice/IBM WebSphere MQ/"); 
props.setProperty("DestName", "DestName") // Destination name
Context ctx = new InitialContext(props);
QueueConnectionFactory connectionFactory = (QueueConnectionFactory) ctx.lookup("Factory");
Connection connection = connectionFactory.createQueueConnection("Username", "Password");
Session queueSession = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queueSend = (Queue) ctx.lookup("DestName");
MessageProducer messageProducer = queueSession.createProducer(queueSend);
TextMessage textMessageSend = queueSession.createTextMessage();
connection.start();
			
textMessageSend.setText("Your message text");
messageProducer.send(textMessageSend);

messageProducer.close();
queueSession.close();
connection.close();

 

Please find the sample script which sends a message to one queue and receives a message from another queue(without using JNDI names):

import com.ibm.msg.client.wmq.*;
import com.ibm.mq.jms.*;
import javax.jms.*;

MQQueueConnectionFactory qcf = new MQQueueConnectionFactory();

// Host and port settings have their usual meanings
qcf.setHostName ("localhost");
qcf.setPort (1414);

// Queue manager and channel — the W-MQ administrator should
//  supply these
qcf.setQueueManager ("TestQueueManager");
qcf.setChannel ("SYSTEM.DEF.SVRCONN");

// Although there are many possible values of transport type,
//  only 'client' and 'bindings' work in a Java client. Bindings
//  is a kind of in-memory transport and only works when the client
//  and the queue manager are on the same physical host. In most
//  cases we need 'client'. 
qcf.setTransportType (WMQConstants.WMQ_CM_BINDINGS);

QueueConnection qc = qcf.createQueueConnection ();
// QueueConnection qc = qcf.createQueueConnection ("Username","password\$");  //set credentials
qc.start();

// Create a queue and a session
    Queue q = new MQQueue ("QueueName");
    Queue q1 = new MQQueue ("QueueName1");
    QueueSession s = qc.createQueueSession (false, Session.AUTO_ACKNOWLEDGE);

   // Create and send a TextMessage
    QueueSender qs = s.createSender (q);
    Message m = s.createTextMessage ("Hello, World!");
    qs.send (m);

  // Receive a TextMessage
    QueueReceiver qr = s.createReceiver(q1);
    qr.receive();

 

Don't forget to copy MQ client libraries to the <ReadyAPI_Install>/bin/ext folder and change values in bold to the applicable values. Please refer to the Requirements section in the JMS Manual Configuration article for details.

    Hi Natsya,

    thanks for the response.

    But can you please assist with the following:

     

    I'm now getting the following error:

    java.lang.LinkageError: loader constraint violation: loader (instance of sun/misc/Launcher$AppClassLoader) previously initiated loading for a different type with name "javax/jms/Destination"

    I've changed the "Destination" a few times... still no luck

     

    I've changed the script with the following:

     

    props.setProperty(Context.PROVIDER_URL, "file:/C:/.hermes/cfg/context/");
    props.setProperty("AIX.ESB.CRTNEWLEAD.IBMI.REQUEST", "AIX.ESB.CRTNEWLEAD.IBMI.REQUEST") // Destination name
    Context ctx = new InitialContext(props);
    QueueConnectionFactory connectionFactory = (QueueConnectionFactory) ctx.lookup("Factory");
    Connection connection = connectionFactory.createQueueConnection();
    Session queueSession = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);

    Queue queueSend = (Queue) ctx.lookup("AIX.ESB.CRTNEWLEAD.IBMI.REQUEST");

     

    The "JMS Administered Objects" file contains the following:

     

    #This file is used by the JNDI FSContext.
    #Thu Jan 04 06:29:49 CAT 2018

        Hi Stephanus,

         

        Sorry, the script may be not clear enough. Please see my configuration of WebSphere MQ attached.

         

        Also, note that we have sample scripts for Working With JMS From Groovy Scripts in our documentation. But, this example is for ActiveMQ provider.

    I have used the second code to connect to IBM MQ. But i am getting error as mentioned below when i run this through soapui.

    My code:

    import com.ibm.msg.client.wmq.*;
    import com.ibm.mq.jms.*;
    import javax.jms.*;

    //public void testMQConnectionMode() throws JMSException {
    // MQConnectionFactory qcf = new MQConnectionFactory();
    // assertThat(cf.getIntProperty(CommonConstants.WMQ_CONNECTION_MODE), is(equalTo(CommonConstants.WMQ_CM_BINDINGS)));
    // cf.setIntProperty(CommonConstants.WMQ_CONNECTION_MODE, CommonConstants.WMQ_CM_CLIENT);
    // assertThat(cf.getIntProperty(CommonConstants.WMQ_CONNECTION_MODE), is(equalTo(CommonConstants.WMQ_CM_CLIENT)));
    //}
    MQQueueConnectionFactory qcf = new MQQueueConnectionFactory();

    // Host and port settings have their usual meanings
    qcf.setHostName ("hostname");
    qcf.setPort (portno);

    // Queue manager and channel — the W-MQ administrator should
    // supply these
    qcf.setQueueManager ("Queuemanager");
    qcf.setChannel ("channelname");

    // Although there are many possible values of transport type,
    // only 'client' and 'bindings' work in a Java client. Bindings
    // is a kind of in-memory transport and only works when the client
    // and the queue manager are on the same physical host. In most
    // cases we need 'client'.
    qcf.setTransportType (WMQConstants.WMQ_CM_BINDINGS);

    QueueConnection qc = qcf.createQueueConnection ();
    // QueueConnection qc = qcf.createQueueConnection ("Username","password\$"); //set credentials
    qc.start();

    // Create a queue and a session
    Queue q = new MQQueue ("MQ");
    Queue q1 = new MQQueue ("MQ1");
    QueueSession s = qc.createQueueSession (false, Session.AUTO_ACKNOWLEDGE);

    // Create and send a TextMessage
    QueueSender qs = s.createSender (q);
    Message m = s.createTextMessage ("Hello, World!");
    qs.send (m);

    // Receive a TextMessage
    QueueReceiver qr = s.createReceiver(q1);
    qr.receive();
