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:
| 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 |

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 ? |
