Can I write publish/subscribe model in straight MQSeries Java API, rather than JMS spec? I am talking MQSeries 5.3? thanks

You can write Pub/Sub applications in any programming environment that can populate an MQRFH2 header.
So, yes, you can do this in the WebSphere MQ API for Java.

Why go to all this trouble writing an RFH2 header in java base when it is so easy using the JMS interface ?  |

Because JMS requires a lot more classes added to the application, and can be slower...
Because JMS hides things that you may possibly need to see or adjust...
Because you are not otherwise using J2EE at all, so why include a piece of it?

As I understand it, the largest performance hit from JMS comes with MDBs. MDBs are around 30% slower than a straight listener - because the app server is so heavily involved.
But the performance report support packs should have much better and more reliable information.
