let's just say integration people are a rare species, no point in burning someone else down, the occasional freebie riders can easily be picked out of the crowed and get put in there place politely...

Just to play devils advocate for a little while....if money isn't a big issue...why not buy in the MQ skills in the form of a new employee? That way you would have onsite help whenever you needed it  |

Well, I look at forums as a place for Q&A, and there's no A without Q
So far as employees goes, it's a question of supply and demand. Supply of people with these skills is low, but demand is even lower. I've just inherited this system from another guy who was responsible for it. It is about 4 years old. This is something I'm putting in place to improve client relationship and improve support (items he apparently thought that important). Once this is done, we're back to really only needing our in-house support skills and limited programming skills. Actually, that's only half true. We've got a pretty decent amount of code working with the queues, in C, but strictly for the purpose of adding and removing messages. Nothing in this area. I'm getting the team training on MQ (and a bunch of other stuff), but it's not there now. |

That makes sense if the demand isn't there. This website is a truly valuable resource, especially when used correctly.
I think most of the rants and flames are directed towards those (thankfully few) people that post what are essentially very basic MQ questions without even attempting to get search results before hand....or even pick up the manual.
I am a long time MVS system programmer and I have to say that I find the MQ Manuals are some of the very best out there...more readable than many of the z/OS ones thats for sure! |

| Thanks for the long sample. I'll need to see if I can accomlish the same in VB or VB.Net as described in the other posting. Java is a no-no at my current client. |

Look at .NET. This means you can still use all the Java objects.
Just instantiate them in .NET (J#)
Enjoy  |
