it was indeed a class problem - more specifically, a class loader problem. Seems that MQ7 has its own class loader? anyway, that class loader interferes with out application's class loader.
In any ... |

btw might there be a set of release notes specific to MQ 7 Java API? particularly any methods that might have been deprecated since MQ 6 (or just a list of changes between MQ 6 and MQ 7)
there is J ... |

well certainly a full recompile of the 'big' app may be in order.

well here's the odd thing - the same code works as a separate application, but within our code, it fails with the 2298.
I stole this sample app from another post here. run separately, it works fine ... |

I'll take a look at filemon but I can confirm that no MQ 6 jars are being used - only MQ 7 jar files.
My classpath is explicitly defined to only point to the 3 MQ jar files I mentioned earlier. No ... |

I can certainly set '-verbose' - but that ... |

MQ 5/6 had a class com.ibm.mq.MQException in the com.ibm.mq.jar file
Has this class been removed in MQ7? Since the MQ7 com.ibm.mq.jar file does not have that class. |
