Howard Kushner,
Can you describe the relationship between JMS and WebSphereMQ, please?
I realize that your book may not cover MQ, but all the questions about this sparked my curiousity.

I do not know much about MQ Series except that its supposed to be a kind of messaging middleware. Consequently, it seems to me that
WebSphere support for JMS, as a J2EE-compliant App Server, would ether meet the same goals or present a competing, conflicting service.
Forgive me if my question to compare JMS and MQ makes little sense and thanks for straightening me out about it.
