Hi all!
I have a following situation:
Two sistems need to be connected over MQSeries, it is kind of
synchronize communication over dynamic queues (20 sec for reply). My backend
sistem is Delphi application. Time is crucial here and the number of
messages is going to be very large, so i am wondering how to connect my
Delphi application to MQS Queues. Can anobody tell can i connect to MQS
through Web Service (threading sistem)!!!!??? Or it must be through dll
file, and what about multithreading then?

Can you help me?

Hi,

the problem seems to be that there is
no Delphi API for MQ Series like C/C++/Cobol/Perl and Java APIs ?
The only way to do this is through a
software layer which adapts to any of
the above APIs. I would check first,
if someone hasn't done that already
(check the support packs page or post a question in MQSeries API Thread on this site).

If there is no complete Delphi API (which is quite large task if you want to support
the full MQI API with the structures
and constants and so on) I suggest writing
a small C-DLL which provides you the
functionality you need, to call from Delphi.
This shouldn't be to hard to do, maybe a couple of days work.

Going through a webservice adapter (which are commercially available or you could roll your own using java) is probably wuite slow and I wouldn't really recommend it.
