and why does it say it can't find the com.ibm.mq.jmqi.local.LocalServer method when it clearly loads it in the verbose output?

I think this could be because the arguments found in the loaded class may be different to those you compiled against and so it cant find a method with the matching signature.
What does the bigger application look like? Does it reside in an application container?
As an aside, you may wish to put the lines of code that clean up rersources in a finally block. |

I totally second this statement.
I believe this sample code looks more or less like your big app code.

well certainly a full recompile of the 'big' app may be in order.
However, I did recompile the MQ specific classes against MQ 7 jars, jar'ed them up, prepended the jar to my classpath, and tried it again, but still no luck. |

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 Javadoc in the MQ package, with list of deprecated classes/functions, but doesn't specify if they were deprecated in MQ 7 or earlier |

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 case, many thanks to those that helped out and gave suggestions - they were very helpful! |

Can you please explain ?
and it will be helpful for rookies like me, if you could share the solution/fix - if it is a general concept and not directly related to your business.

sounds like what happened to us.
