how to groovy script with jms websphere

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,

 

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
    TTSUAENODE01CF/RefAddr/3/Encoding=String
    TTSUAENODE01CF/RefAddr/38/Encoding=String
    TTSUAENODE02CF/RefAddr/24/Encoding=String
    TTSUAENODE02CF/RefAddr/70/Encoding=String
    TTSUAENODE01CF/RefAddr/110/Type=XMSC_WMQ_SSL_KEY_RESETCOUNT

    TTSUAENODE02CF/RefAddr/110/Type=XMSC_WMQ_SSL_KEY_RESETCOUNT

    ...

      This error appears with both script samples..

        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();

    -----------------------------------------------------------------------
    | Failed to load the WebSphere MQ native JNI library: 'mqjbnd'.
    |
    | The JVM attempted to load the platform native library 'mqjbnd',
    | which was mapped to the filename: 'mqjbnd.dll'.
    |
    | When attempting to load the library, the JVM reported the error
    | message:
    | 'no mqjbnd in java.library.path'
    |
    | The JVM's bit-size is: '64'
    |
    | The library path which was used to locate this library was:

    | ********************************************************************'
    |
    | Check that the bit size of the JVM matches the bit size of the first
    | native library file located within this java.library.path directory
    | list.
    |
    | The native library 'mqjbnd' is used by the WebSphere MQ classes for
    | Java and WebSphere MQ classes for JMS when creating a connection to
    | the queue manager using a 'bindings' mode connection. A bindings
    | mode connection is a connection which uses the system's memory to
    | communicate with the queue manager, as opposed to a 'client' mode
    | connection which uses a TCP/IP socket.
    |
    | In order to communicate with a queue manager using a bindings mode
    | connection, the queue manager must be located on the same system as
    | the WebSphere MQ classes for Java/JMS. If this is not the case in
    | your environment, consider reconfiguring the application to utilise
    | client mode connections.
