I am not a programmer, but need to build a native PTP code, eventually with a MQ TX MGr (I am assuming the MQ native allows TX use, but not the MQ JMS)

From this site:


http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=%2Fcom.ibm.mq.csqzaw.doc%2Fuj11050_.htm
I got hte following code:

// WebSphere MQ classes for Java sample application
//
// This sample runs as a Java Application using the command :- java MQSample
//
// @(#) javabase/samples/MQSample.java, java, j000 1.8 04/12/03 10:59:49

import com.ibm.mq.*;            // Include the WebSphere MQ classes for Java package


public class MQSample
{
  private String qManager = "your_Q_manager";  // define name of queue
                                               // manager to connect to.
  private MQQueueManager qMgr;                 // define a queue manager
                                               // object
  public static void main(String args[]) {
     new MQSample();
  }

  public MQSample() {
   try {

      // Create a connection to the queue manager

      qMgr = new MQQueueManager(qManager);

      // Set up the options on the queue we wish to open...
      // Note. All WebSphere MQ Options are prefixed with MQC in Java.

      int openOptions = MQC.MQOO_INPUT_AS_Q_DEF |
                        MQC.MQOO_OUTPUT ;

      // Now specify the queue that we wish to open,
      // and the open options...

      MQQueue system_default_local_queue =
              qMgr.accessQueue("SYSTEM.DEFAULT.LOCAL.QUEUE",
                               openOptions);

      // Define a simple WebSphere MQ message, and write some text in UTF format..

      MQMessage hello_world = new MQMessage();
      hello_world.writeUTF("Hello World!");

      // specify the message options...

      MQPutMessageOptions pmo = new MQPutMessageOptions(); // accept the // defaults,
                                                           // same as MQPMO_DEFAULT

      // put the message on the queue

      system_default_local_queue.put(hello_world,pmo);

      // get the message back again...
      // First define a WebSphere MQ message buffer to receive the message into..

      MQMessage retrievedMessage = new MQMessage();
      retrievedMessage.messageId = hello_world.messageId;

      // Set the get message options...

      MQGetMessageOptions gmo = new MQGetMessageOptions(); // accept the defaults
                                                           // same as  MQGMO_DEFAULT
      // get the message off the queue...

      system_default_local_queue.get(retrievedMessage, gmo);

      // And prove we have the message by displaying the UTF message text

      String msgText = retrievedMessage.readUTF();
      System.out.println("The message is: " + msgText);
      // Close the queue...
      system_default_local_queue.close();
      // Disconnect from the queue manager

      qMgr.disconnect();
    }
      // If an error has occurred in the above, try to identify what went wrong
      // Was it a WebSphere MQ error?
    catch (MQException ex)
    {
      System.out.println("A WebSphere MQ error occurred : Completion code " +
                         ex.completionCode + " Reason code " + ex.reasonCode);
    }
      // Was it a Java buffer space error?
    catch (java.io.IOException ex)
    {
      System.out.println("An error occurred whilst writing to the message buffer: " + ex);
    }
  }
} // end of sample


When I compile it, the compiler reports that several items have been deprecated. I have seen that issue with other MQ exapmles as well

Where can I get a current and up to date Native code example ?

Thanks

...

v6r0 = unsupport version of MQ.
Try http://pic.dhe.ibm.com/infocenter/wmqv7/v7r5/index.jsp

You will find Java sample code in a WMQ server installation that included the "samples" component.

I looked in that site, but could not find any example programs for JMS.

The closet I found was a page which discuses JMS extensions, but did not give a JMS example program that do not contain deprecated objects

Is there any place I can find a current example JMS program and how to compile and invoke it ?
