kishore,
I just found this note and wanted to post the information that I had sent over to you, so that it will hopefully help the community -- sorry that you are seeing this twice
I don't have any Java code around OAQ, unfortunately, and have only seen it used at a couple of clients (Coca-Cola and UPM). There is very little documentation around this, but it does work reliably. I've worked primarily on the performance side - optimizing OAQ and OTM threads in order to increase the integration throughput.
However, I work with one of the engineers who designed the Coca-Cola OAQ integration, but he's usually working and isn't an active member of the forums.
I'll try to get more details from him and post them here.
Thanks,
Chris
