Hi all!
I have to migrate a Java class that use MQ libraries to JMS, _without_ using any non-Sun libraries. I'm a JMS newbie.
Old _working_ code is:
| Code: |
MQQueueManager oQm=null;
MQQueue oQIn=null;
MQPutMessageOptions oPmo=null;
MQMessage oMsgIn=null;
int iOpenOptionsIn;
MQQueue oQOut=null;
MQGetMessageOptions oGmo=null;
MQMessage oMsgOut=null;
int iOpenOptionsOut;
String sHostOutputString = "";
oQm = new MQQueueManager(getSendQueueManagerName());
iOpenOptionsIn = MQC.MQOO_OUTPUT | MQC.MQOO_INQUIRE | MQC.MQOO_SET_IDENTITY_CONTEXT;
oQIn = oQm.accessQueue(getInQueueName(),iOpenOptionsIn);
oPmo = new MQPutMessageOptions();
oPmo.options = MQC.MQPMO_SET_IDENTITY_CONTEXT | MQC.MQPMO_FAIL_IF_QUIESCING;
oMsgIn = new MQMessage();
oMsgIn.messageType = MQC.MQMT_DATAGRAM;
oMsgIn.format = MQC.MQFMT_STRING; // "MQSTR"
oMsgIn.replyToQueueManagerName = getReceiveQueueMgrName();
oMsgIn.characterSet = 923;
oMsgIn.replyToQueueName = "returnQueue";
oQIn.put(oMsgIn,oPmo);
oQm.disconnect();
oMsgOut = new MQMessage();
oMsgOut.messageId = oMsgIn.messageId; /
oMsgOut.format = MQC.MQFMT_STRING; // "MQSTR"
oMsgOut.characterSet = 923;
oGmo = new MQGetMessageOptions();
oGmo.options = MQC.MQGMO_WAIT | MQC.MQGMO_FAIL_IF_QUIESCING;
iOpenOptionsOut = MQC.MQOO_INQUIRE | MQC.MQOO_INPUT_AS_Q_DEF;
oQOut = oQm.accessQueue(getOutQueueName(),
iOpenOptionsOut); //getOutQueueName returns the name of the queue
oQOut.get(oMsgOut,oGmo);
sHostOutputString = oMsgOut.readString(oMsgOut.getTotalMessageLength());
oQOut.close();
oQm.disconnect();

I tried to migrate to a class with this code:
| Code: |
Context context = new InitialContext ();
queueConnectionFactory = (QueueConnectionFactory) context.lookup("QCF");
queue = (Queue) context.lookup("Q");
queueConnection = queueConnectionFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);
queueConnection.start();
TextMessage message = queueSession.createTextMessage();
message.setText(sHostInputString);
QueueSender requestSender = queueSession.createSender(queue);
Queue replyQueue = queueSession.createQueue("QueueName");
QueueReceiver replyReceiver = queueSession.createReceiver(replyQueue);
message.setJMSReplyTo(replyQueue);
message.setJMSDeliveryMode(DeliveryMode.PERSISTENT);
requestSender.send(message);
Message responseMessageAsMessage = replyReceiver.receive(20000);
TextMessage responseMessage = (TextMessage) responseMessageAsMessage;
sHostOutputString = responseMessage.getText();
|
All seems to work until send operation. But I receive no response. I think that header message is not set correctly.
How can I "translate" operation like
| Code: |
iOpenOptionsIn = MQC.MQOO_OUTPUT | MQC.MQOO_INQUIRE | MQC.MQOO_SET_IDENTITY_CONTEXT;
...
oPmo.options = MQC.MQPMO_SET_IDENTITY_CONTEXT | MQC.MQPMO_FAIL_IF_QUIESCING;
|
in a "JMS-mode" without using com.ibm.mq package???
Thanks a lot, it is very important and also urgent for me
Ciao[/code] |

As to your question : You don't.
There is no setting of options as the JMS classes will do that for you.
Enjoy  |

After 8 years? I'm not surprised. Mr Google can find you fresher versions.

He should have found others. You don't get search engines the way you used to when I was a lad.....
