I'm new to MQSeries Java so please bear with me. I am trying to programmatically create a handful of queues in MQ depending up real time data I'm ingesting. I have been using the MQ Simulator for Java Developers in WSAD and also the "Embedded Messaging" and I'm obtaining the same results with both.
Here is my code:
MQQueueManager queueManager = new MQQueueManager("WAS_localhost_server1");
MQQueue myQueue = queueManager.accessQueue("DynamicQueue1", MQC.MQOO_OUTPUT, "DynamicQueue1", null, null);
The queueManager is connected but when I try to execute the "accessQueue" method I get this exception:
com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2196
I don't understand the "model queue" type which the api refers to with this method. I have tried several types of open options but nothing seems to work. I'm not using any security so this should help. I don't know if I need to get the JMSAdmin tool working but that is a whole other issue of things not working. Any help would be appreciated. |

Hi,
Your problem has nothing to do with the JMSAdmin tool because you are not using JMS!!!
Time to RTM.
Think of a model queue as a template. By default, when you create a queue manager, a default model queue is created called: 'SYSTEM.DEFAULT.LOCAL.QUEUE'
Therefore, your code should look like:
| Code: |
String inputQName = "SYSTEM.DEFAULT.MODEL.QUEUE";
String DynamicQName = "ABC.*";
String replyQName = null;
int openInputOptions= MQC.MQOO_INQUIRE + MQC.MQOO_FAIL_IF_QUIESCING + MQC.MQOO_INPUT_SHARED;
MQQueueManager _qMgr = new MQQueueManager(qMgrName);
MQQueue _inQ = _qMgr.accessQueue( inputQName,
openInputOptions,
null, // default q manager
DynamicQName, // dynamic q name
null ); // no alternate user id
replyQName = _inQ.name; // save this!!! |
Please download and read the WMQ Using Java manual.

Roger,
Thanks so much for replying. I have read and browsed 3 red books and couldn't find the information your gave me. Everything is working now. I will also read the WMQ Using Java you suggested.
Thanks for your help !! |

And as you are obviously in a Web Application Server (WAS) I would suggest you move to JMS and not base Java.
If you are using Websphere WAS 5.x the JMS configuration should take place in the Admin console (does not use JMSAdmin). Check for the right provider : Websphere MQ JMS. You need to specify the model queue / and default name pattern for temporary queues on the qcf / tcf
You will need a full MQ Server to be linked to WAS. The internal MQ is severely restricted and will not allow communication to outside qmgrs.
Enjoy  |
