We have noticed an application error, unable to create a session when connecting to Migrated MQ in our Test environment. The JMS pub/sub application connection is from Weblogic and current version of WMQ v7.0.1.1(the previous version was MQ v6.0.2.8 ) on Windows 2003, sp2. But it worked fine when it was connecting to the previous version of MQ. Are there any major application changes required, to connect to the new MQ 7.0. ( i haven't seen in one in IBM documentation for migration)
I am not a jms guy, so dont understand what exactly causing the issue.
Greatly appreciate any help/suggestions. Please see the error message below: (changed the actual names)
ERROR
xxxx.abc_xxxxxx_bridge.abc_xxxxx_bridge.jmscxn.wxyz.jms.JMSTopicConnection(770) - Error creating new map message: JMSCC0033: A synchronous method call is not permitted when a session is being used asynchronously: 'createMapMessage'
com.ibm.msg.client.jms.DetailedIllegalStateException: JMSCC0033: A synchronous method call is not permitted when a session is being used asynchronously: 'createMapMessage' The JMS specification does not permit the use of a session for synchronous methods when asynchronous message delivery is running. Create a separate session if you wish to use both synchronous methods and asynchronous delivery simultaneously.

Nothing related to com.ibm.mq.X appears in your exception - why is it thought something within MQ went wrong?
Did your application change at the same time as you upgraded MQ? |

No application changes were made before or after MQ upgrade. Guess MQ should have went wrong, because the same application was working fine with v6.0 until the migration. This is the new error we noticed only after the migration. no clues..  |

There are lots of clues, in the exceptions you pasted. There is no mention of com.ibm.mq but lots of mentions of other classes. Check with the owners of those classes. |

You cannot use the session used to receive a message in an MDB to create an outbound message and connection. You have to create an additional session (from the same connection) to send your response.
This is what the message is telling you. Have fun
