I am having difficulty getting a demo JMS application running using the Pub/Sub services of MQSeries.
When I subscribe or publish I get the following MQ errors (javax.jms.JMSException: MQJMS3011: Failed to publish message to MQ queue) and (javax.jms.JMSException: MQJMS3009: Failed to publish command to MQ queue). I also get a error on my console indicating that MQ was unable to (Unable to load message catalog - mqji)
I have installed the following components on NT:
1) MQSeries 5.2.1 for NT
2) MA88: MQSeries classes for Java and MQSeries classes for Java Message Service (latest version from supportpac site)
3) MA0C: MQSeries Publish/Subscribe. (latest version from supportpac site)
I have started the queue manager, and the broker and have verified that they are both running. It doesn't appear there are any problems there.
I have configured JNDI with the JMSAdmin tool with the following:
1) define tcf(TopicConnectionFactory) BROKERPUBQ(SYSTEM.BROKER.DEFAULT.STREAM) BROKERVER(V1) HOSTNAME(localhost) TRANSPORT(CLIENT) PORT(1414) BROKERQMGR(QM_install) QMANAGER(QM_install) CHANNEL(SYSTEM.DEF.SVRCONN) BROKERCONQ(SYSTEM.BROKER.CONTROL.QUEUE)
and a single topic
2) def t(Hot Deals) PERSISTENCE(PERS)
TARGCLIENT(JMS)
EXPIRY(APP)
ENCODING(NATIVE)
VERSION(1)
PRIORITY(APP)
TOPIC(Hot Deals)
Here's a sample of my subscriber ....
Properties env = new Properties();
// ... specify the JNDI properties specific to the vendor
//env.put(Context.SECURITY_PRINCIPAL, "guest");
//env.put(Context.SECURITY_CREDENTIALS, "guest");
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
env.put(Context.PROVIDER_URL, "file:/C:/jndi-provider");
InitialContext jndi = new InitialContext(env);
factory = (TopicConnectionFactory)jndi.lookup("TopicConnectionFactory");
connect = factory.createTopicConnection ();
connect.setClientID(username);
session = connect.createTopicSession(false,Session.AUTO_ACKNOWLEDGE);
hotDealsTopic = (Topic)jndi.lookup("Hot Deals");
>>>> Failure occurs when the following statement is invoked
subscriber = session.createDurableSubscriber(hotDealsTopic,
"Hot Deals Subscription");
>>>>>
subscriber.setMessageListener(this);
connect.start();
Any feedback would be welcome. I have been investigating this problem for a couple of days now, and I am now officially STUMPED. 
Many thanks for your time! |

Ah yes indeed ... here's what I get when I do that.
com.ibm.mq.MQException: Completion Code 2, Reason 2334
java.lang.Throwable(java.lang.String)
java.lang.Exception(java.lang.String)
com.ibm.mq.MQException(int, int, java.lang.Object)
void com.ibm.mq.MQQueue.put(com.ibm.mq.MQMessage, com.ibm.mq.MQPutMessageOptions)
void com.ibm.mq.jms.MQTopicPublisher.publish(javax.jms.Message, int, int, long)
void com.ibm.mq.jms.MQTopicPublisher.publish(javax.jms.Message)
void JMSPubSub.main(java.lang.String [])
Any thoughts?

I've noticed others with the same problem have fixed it by "upgrading" to the appropriate MA88 for their installation. I've dowloaded the latest from the supportPac site, and I have MQSeries 5.2.1 installed. Is there a different version of the supportPac that I should be using?
Also, I have now installed the CSD05 (PTF U200095) SupportPac to see if it would make a difference, and the result has NOT changed.
And again, to just reiterate, I've also installed ma0c (specifically ma0c_ntmq52.exe) for the pub/sub function. Again, no improvement. I wonder, should I step it back and try ma0c_nt.zip?
Thanks folks ... these things can be so frustrating. Days can just pass by without resolution! |

I've found the solution to my problem. I had installed the sun jdk 1.3. As it turns out, the prerequisites state that the IBM jdk is supported (but doesn't mention the sun jdk). Therefore, I installed the IBM jdk, and voila, it's working.
Many thanks for the input provided.
Cheers ...  |
