Hi all,
I have written a sample message driven bean, which simple rollsback the message by calling setRollbackOnly() on the txnContext. What i'm trying to achieve is after 4 such rollbacks(i.e message is redelivered 4 times) , the system should move the message to another queue. For this i configured my queue with a backout queue name and backout threshold. The system rollsback the message and after 4 attempts it indeeds moves the message to the backout queue. The problem is while it rollsback the message it thows a weired JMSException as given below :
[1/28/04 16:50:28:421 GMT+05:30] 3650f550 SystemOut O Inside the JMS Exception block with jms message Rolling back the current transaction.
[1/28/04 16:50:33:421 GMT+05:30] 28957542 JMSExceptionL W WMSG0018E: Error on JMSConnection for MDB JMSTester , JMSDestination jms/jmsTesterQ : javax.jms.JMSException: MQJMS1016: an internal error has occurred. Please contact your system administrator. Detail: {0}
at com.ibm.mq.jms.services.ConfigEnvironment.newException(ConfigEnvironment.java:540)
at com.ibm.mq.jms.MQQueueAgentThread.run(MQQueueAgentThread.java:1583)
at java.lang.Thread.run(Thread.java:512)
The connection has been configured with XA option.
My environment is MQ 5.2 and websphere application server 5.0
The MQ documentation unfortunately does not say anything about MQJMS1016.
Any inputs etc. |

First, I'd suggest that you move forward from MQ 5.2 (which is no longer supported) to WMQ 5.3. You are probably using a version of the MA88 classes, and there have been a lot of changes that you don't have.
Second, this looks like the kind of exception that would throw an *.FDC file. Do you have anything in your mq\errors subdirectory? |

| Your FDCs are from December, and they are related to problems with endmqm. I don't think they have a thing to do with your current MDB problems. |

Hi,
I took inputs from the first reply (a possibility of jar being of older versions) and landed at this location
http://www.developer.ibm.com/tech/faq/results/0,1322,1%253A401%253A407%253A36%253Amqjava,00.html#q36
This link took me to the following page to download the jar files
https://www6.software.ibm.com/dl/wsmqcsd/wsmqcsd-p
where i finally downloaded
"WebSphere Embedded Messaging interim fixes for WebSphere Application Server V5.0.2"
I applied the new jar and surprisingly it worked, and the exceptions are not coming at the same time the messages gets redirected to the backout queue after N number of failure attempts.
Also i noticed that on 5.2 if you specify a backout queue name then i get the exception message, as soon as i remove the backout queue name from the queue deinition i exceptions stopped appearing.
Howver i could not fully understand why it worked cos the link says that the jars are for MQ ver 5.3
Could you pls given your inputs on that. Should i recommend this jar for the production environment too.
Thanks a lot for your inputs
Regards
Prash |

| I'm not sure that I'm 100% clear on what you've tried/haven't tried and why things are working/not working. However, I can tell you that MQ 5.2 went out of support and you shouldn't be recommending this to your customers in a production environment. They should be using WMQ 5.3. |
